1 FLECS Concepts This section describes Halliburton’s FLECS system and how the FLECS CT application

relates to the FLECS System.

1.1 FLECS System Concepts

The FLECS system consists of two primary components. The FLECS display and the

FLECS card stack. The FLECS display has a 6.3 inch color display, a touch screen and a

keypad. The FLECS card stack contains a computer and hardware for interfacing with

instrumentation such as pressure transducers and optical encoders.

Software is written to run on the FLECS system. The software for coiled tubing is called

“FLECS CT”. This manual discusses the operational aspects of the FLECS CT

application.

1.2 FLECS Display

This section describes the components of the FLECS display and general information on

how to use the components.

There are two version of the FLECS Display deployed on Halliburton Coiled Tubing

equipment. The most common is the safe area display, used primarily for land units. The

safe area display is illustrated in this document. The second display is a modified version

of the safe area display, for use in hazardous area equipment.

The hazardous area display does not have a touch screen. Operation of the hazardous area

display is accomplished with keypad navigation. The same keypad navigation

functionality is implemented on the safe area display. Refer to Section 3 of this document

for more information on using Keypad Navigation.

1.2.1 FLECS Display Screen

The FLECS display has three major components. The display contains a color screen.

This screen is similar to the monitor on a desktop computer.

Figure 1 - FLECS Display with Screen Highlighted

6

1.2.2 FLECS Display Touch-screen

The safe area display has a touch-screen. A touch-screen enables the operator to take

action by pressing directly on the screen with a finger. The touch-screen is much like a

mouse found on desktop computers. Using a mouse one moves the cursor over objects on

screen and clicks to take some action. Touching an object illustrated on the FLECS

screen has the same effect as moving the mouse over an object and clicking.

Figure 2 - FLECS Display with Touch-Screen Highlighted

1.2.2.1 FLECS Display Touch-screen Extended Touchable Area

The touch-screen is slightly larger than the screen. To the left and right of the screen are

what appears to be five buttons. These buttons are part of the touch-screen. Touching in

these areas is like pressing a button on the FLECS keypad. This part of the touch-screen

is called the extended touchable area.

Figure 3 - FLECS Display with Extended Touchable Area Highlighted

1.2.3 FLECS Display Keypad

The FLECS display has a keypad for entering information and for operation without the

touch screen. The keys are located below and to the right of the screen.

7

Figure 4 - FLECS Display with Keypad Highlighted

Most of the keys on the keypad have two functions. The primary function of the button is

the larger character printed in the center of the button. The secondary function of the

buttons is printed in smaller text on the lower right corner of the button.

Figure 5 – Key with Primary and Shifted Function Illustrated

The secondary function of the button is called the “shifted” function. The keypad has a

shift button labeled “SHIFT LOC”. When the shift function is enabled the red dot on the

lower right corner of the shift button will be illuminated. When shift is enabled pressing a

button will cause the secondary character to be entered. Pressing the shift button changes

the state of the shift.

1.2.4 FLECS Display Power Indicator

To the left of the screen is a red light which indicates power is being supplied to the

FLECS Display.

8

Figure 6 – Power Indicator, Illuminated

2 FLECS CT Concepts This section describes fundamental concepts of operating a FLECS CT system. These

concepts apply throughout the FLECS CT application.

2.1 FLECS CT Interface Organization

The interface for FLECS CT is divided into two primary sections. These two parts are

called the “constantly visible” and the “context dependent” sections.

2.2 Constantly Visible Display

The right one third of the screen is called the constantly visible section of the screen. This

part of the screen provides information that is critical for coiled tubing operations. This

information will always be visible on screen. Figure 7 highlights the constantly visible

section of the display.

The constantly visible section of the display is divided into three parts. The top third

provides information related to the tubing weight. The middle third provides information

related to the depth, speed and direction of tubing movement. The bottom third provides

the tubing and wellhead pressure.

Figure 7 – FLECS CT Display with Constantly Visible Display Highlighted

9

2.3 Context Dependent Display

The left two thirds of the screen is called the context dependent section of the screen.

Figure 8 highlights the context dependent section of the display. This part of the screen

provides information from additional sensors. This section of the screen is also used to

display menus for configuring the FLECS CT system.

The information from additional sensors is only displayed when all configuration menus

are closed. This part of the screen works similar to a Microsoft Windows desktop

computer. On a computer running Windows, when all applications (Word, Outlook, etc)

are closed you see the “desktop”. The “desktop” for FLECS CT displays information

from additional sensors. The information from these additional sensors is covered up

when a menu is opened for another reason.

Figure 8 – FLECS CT Display with Context Dependent Display Highlighted

2.4 Context Menu

In the FLECS CT application there are some operations which are infrequently

performed. Because of the limited space available on the FLECS screen, infrequently

used operations are hidden in what is called a context menu.

Throughout the FLECS CT application the context menu is accessed by pressing the

lower left most part of the touch screen or by pressing the F1 key. The area which opens

the context menu in FLECS CT is highlighted in Figure 9. This is called the context

menu button.

10

Figure 9 – FLECS CT with Context Menu Button Highlighted

When a context menu is open, a second press to the context menu button closes the

context menu.

When using a desktop computer running Microsoft Windows a right click on an object

causes a context menu to be displayed. For example if you right click on a folder in

Windows, a menu with options specific to that folder is displayed.

One can think of the context menu in FLECS CT like a right click in Windows. When

you press the context menu button in FLECS CT relevant options will be presented.

3 Keypad Navigation The FLECS CT software can be operated using either the touch screen or buttons on the

keypad. For hazardous area units keypad navigation is the only method of interacting

with the FLECS CT system. For safe area units the operator may use both the touch

screen and keypad navigation.

3.1 FLECS CT Desktop

The term “FLECS CT Desktop” refers to the state in which all menus are closed and the

six custom inputs are visible in the context dependent section of the screen. The custom

inputs are visible only when all other menus are closed. See Section 2.3 for more

information on the context dependent section of the screen.

3.2 Key Hints

FLECS CT uses key hints to show the operator what button on the keypad is the same as

touching an item on screen.

3.2.1 Desktop Key Hints

In Figure 10 the FLECS CT desktop is illustrated. In this illustration key hints are turned

on. The square with the four arrows and the word “Enter” in the top right is the currently

selected square. When an arrow key is pressed the selected square moves in the direction

of the arrow. Pressing the enter key has the same effect as touching in the selected square.

11

In the bottom right of Figure 10 there are two small squares. The upper square contains

the text “F7” and a symbol. The lower square contains the text “F8” and a symbol. These

tabs indicate that touching the extended touchable area buttons to the right of the tab will

have some effect. They also indicate that a press of the F7 key is the same as touching on

the touch screen in the extended touchable area. See Section 1.2.2.1 for more information

on the Extended Touchable Area.

While at the desktop as illustrated in Figure 10, if key hints are not enabled pressing an

arrow key or the enter key does not have any effect. However, the function keys F7 and

F8 are operational even if key hints are not displayed.

Desktop key hints are automatically hidden from view if no key is pressed for 15

seconds.

Figure 10 - Desktop Key Hint Label Illustration

3.2.2 Key Hints in Menus

When a menu is opened and key hints are enabled a hint appears over each part of the

screen which could be pressed with the touch screen. Pressing the key indicated by the

key hint is the same as touching on the item with the touch screen.

In Figure 11 the button labeled “Load Pin Setup” has a key hint in the top right

containing the text “F6”. This key hint indicates that pressing the F6 key is the same as

touching on the Load Pin Setup button.

Keypad navigation works for menus even if key hints are disabled. Key hints are always

numbered beginning with F2. Generally the items on screen are assigned keys left to

right, then top to bottom.

12

Figure 11 - Key Hint Label Illustration

3.3 CTRL Key

The CTRL key is used to enable and disable key hints. Each press of the CTRL key

changes the state of key hints. If key hints are off and CTRL is pressed key hints will be

turned on. If key hints are on and CTRL is pressed key hints will be turned off.

4 Entering Calibration Points The FLECS CT application uses a common process for adding calibration points for load

pins and the pressure transducers. The process of deleting existing calibration points is

also common.

Beginning in version 1.1 it is no longer possible to modify an existing calibration. The

incorrect calibration point must be deleted and then a new point added.

This section discusses the process of adding and deleting calibration points.

4.1 Add Calibration Point

After pressing the “Add Point” button from either the Load Pin Setup or transducer setup

screen, the Add Calibration Point mA screen is displayed. The first screen, illustrated in

Figure 12, prompts for the mA value of the calibration point.

4.1.1 mA Value Entry

Enter the mA value of the new calibration point in the text field. This field accepts

numeric values with up to two decimal places. The field will not allow numbers which

are out of the valid range indicated by the Range Bar.

After entering the mA value touch the Next button. The Next button will not be enabled

unless a valid value is entered in the mA field. To cancel the Add Calibration Point

process, touch the Cancel button.

13

Figure 12 – Add Calibration Point mA

4.1.1.1 mA Valid Range Bar

The center of the Add Calibration Point screen displays the valid range for a calibration

point mA value. This range is displayed by the green bar. This bar is called the Range

Bar. The Range Bar is surrounded by a blue oval in Figure 13.

Figure 13 – Add Calibration Point mA – Range Bar Detail – No Existing Points

4.1.1.1.1 Minimum mA Value

In Figure 13 the minimum mA value which can be entered is indicated below the left end

of the Range Bar. This value is enclosed in a red rectangle.

4.1.1.1.2 Maximum mA Value

In Figure 13 the maximum mA value which can be entered is indicated below the right

end of the Range Bar. This value is enclosed in a green triangle.

4.1.1.1.3 Existing Point Ranges

14

The mA value of any existing calibration points will be illustrated on the Range Bar with

an Existing Point Range. An Existing Point Range is illustrated with a red bar. The

Existing Point Range will be illustrated on top of the green Range Bar.

For some sensors a minimum spacing between the mA values of calibration points is

required. In this case the red Existing Point Range illustrates the range of mA values not

allowed because they are too close to an existing calibration point.

Figure 14 illustrates the Add Calibration Point mA screen with one existing point at 6.0

mA. The red Existing Point Range is detailed by a green triangle.

Figure 14 – Add Calibration Point mA – Existing Point

4.1.1.1.4 Entered Point Indicator

When a value is entered in the mA field a representation of that value is illustrated on the

Range Bar. This is called the Entered Point Indicator. The Entered Point Indicator is

illustrated with a tall, orange bar. The Entered Point Indicator bar moves each time a new

mA value is entered. In Figure 15 the Entered Point Indicator is highlighted with a blue

oval.

15

Figure 15 – Add Calibration Point mA – Entered Point Indicator

If a mA value is entered which overlaps the Existing Point Range of another calibration

point a message will be displayed under the mA field. The Next button will be disabled.

This situation is illustrated in Figure 16.

Figure 16 – Add Calibration Point mA– Invalid Point Entered

4.1.2 Value Entry

After confirming the mA value FLECS CT prompts for the value corresponding to the

entered mA value. For load pins the requested value will be a weight. For pressure

transducers the requested value will be a pressure. The display value is requested in the

selected units for the sensor.

After entering a value press the Finish button. Press cancel to exit the add calibration

point process without changing the sensor calibration.

The display value field will not allow entry of a value outside the valid range.

16

Figure 17 illustrates the screen used to enter the display value corresponding to the mA

value previously entered. In this example the calibration point is being added for a

pressure transducer.

Figure 17 – Add Calibration Point Value

4.1.2.1 Value Range Bar

The center of the Add Calibration Point screen displays the valid range for a calibration

point value. This range is displayed by the green bar. This bar is called the Display Value

Range Bar. The Display Value Range Bar is surrounded by a blue oval in Figure 18.

Figure 18 – Add Calibration Point Value

4.1.2.1.1 Minimum Display Value

In Figure 18 the minimum display value which can be entered is indicated below the left

end of the Range Bar. This value is enclosed in a red square.

4.1.2.1.2 Maximum Display Value

In Figure 18 the maximum display value which can be entered is indicated below the

right end of the Range Bar. This value is enclosed in a green triangle.

17

4.1.2.1.3 Existing Points

The valid range indicated by the range bar is calculated with respect to other existing

calibration points. The example in Figure 18 illustrates the display range bar for a

pressure transducer which had no existing calibration points. Because no other calibration

points existed the display value corresponding to the mA value could be anywhere

between 0 and 20,000 PSI.

4.1.2.1.4 Entered Point Indicator

When a value is entered in the display value field a representation of that value is

illustrated on the Range Bar. This is called the Entered Point Indicator. The Entered Point

Indicator is illustrated with a tall orange bar. The Entered Point Indicator bar moves each

time a new mA value is entered. In Figure 19 the Entered Point Indicator is highlighted

with a blue oval.

Figure 19 – Add Calibration Point Value – Entered Point Indicator

4.2 Delete Calibration Point

After touching on an existing calibration point the Delete Point button will be enabled.

Press the Delete Point button to delete the point. Press cancel to exit this screen without

modifying the sensor calibration.

18

Figure 20 - Delete Calibration Point Confirmation

5 Sensor and Actuator Connection Selection The FLECS CT system uses a common interface for setting where a sensor or actuator is

connected to the FLECS controller. Because this screen is common to all of the devices,

it is discussed generally in this section rather than duplicating the information several

times.

This section describes how to use the connection screens found in FLECS CT.

5.1 Overview

The connection selection page is divided into two parts. The top part indicates the

currently selected input or output. The bottom part enables the operator to change which

input or output the device is connected to.

5.1.1 Current Selection

When the FLECS CT software is initially installed the inputs and outputs used for sensors

and outputs used for actuators will not be set. Under this condition the input selection

screen will look similar to Figure 21.

19

Figure 21 - Connection Selection - Input Not Set

The top half of the display indicates that an input has not been assigned to the sensor yet.

Once an input has been selected the top half of the connection selection screen will show

which input is selected. This is illustrated in Figure 22.

Figure 22 - Connection Selection - Input Selected

5.1.2 Changing the Selection

To change which input or output is used use the arrow buttons to increase or decrease the

selection. The newly selected input or output is in the box between the two arrow buttons.

If the new selected input is already in use by this or another device, the apply button will

be disabled and the message “Analog Input Is In Use” will appear.

When the desired input is selected and it is available, press the apply button to make the

change effective. When the change is made, the top half of the screen will change to

show the newly selected input.

20

6 Weight Display The Weight display is the top one third of the Constantly Visible section of the screen.

The Weight display provides the current weight, the units the weight is displayed in and

the status of the load limiting system.

This section discusses general capabilities of the weight display system in FLECS CT

and describes the interface used for managing all aspects of the weight display.

Figure 23 – Weight Display

6.1 FLECS CT Weight Measurement

The FLECS CT system supports measurement of tubing weight using either one or two

load pins. Each configured load pin has an independent calibration table1. A load pin

calibration table must have at least two calibration points to be a valid calibration. A load

pin calibration table can consist of up to fifteen points.

When only one load pin is configured the force applied to the single load pin is doubled

to calculate the display weight. This is based on the assumption that exactly fifty percent

of the load is applied to the single installed pin.

When two load pins are configured the sum of the force applied to each pin is used for

the display weight.

6.2 Current Weight

The majority of the Weight display is used for display of the current tubing weight. In

Figure 24 the current weight has a red box around surrounding it. The weight is displayed

in the units selected on the Weight Display Configuration screen. The currently selected

unit has a blue oval around it in Figure 24.

Figure 24 – Weight Display, Current Weight & Units Highlighted

1 A calibration table relates the signal from a transducer to a display value. For example the most basic

calibration for a load pin might consist of two points: (4.00 mA, -17000 lbs) & (20.00 mA, 53000 lbs).

21

A value for the weight is displayed only if one or two load pins are configured and each

configured load pin has an input selected and a valid calibration table.

6.3 Limiting System Status

Just below the Current Weight display is the Load Limiting Status. The Load Limiting

status area is circled with a blue oval in Figure 25. The Load Limiting system is

discussed in Section 9 - Limiting System (Page 44).

Figure 25 – Weight Display – Load Limiting Status Highlighted

6.4 Weight Display Configuration

A touch in the Weight constantly visible area will open the Weight Display Configuration

menu. The Weight Display Configuration menu is displayed in the context dependent

section of the screen.

Figure 26 - Weight Display Configuration Menu

6.4.1 Load Pin Setup

The Load Pin Setup button opens the Load Pin Setup menu. From the Load Pin Setup

menu the number of pins to be used, the input each pin is connected to and the calibration

tables for each pin are configured.

6.4.1.1 No Pins Configured

When the FLECS CT software is initially installed or after all existing load pins are

deleted the load pin setup screen displays a message indicating no pins exist. Use the

22

context menu to add one or two load pins as appropriate. See Section 2.4 for more

information on the context menu.

Figure 27 - Load Pin Setup - No Pins Configured

6.4.1.2 Pin Selection

After one load pin has been added the load pin setup screen changes to look like that in

Figure 28. There is a single tab on the left side of the screen labeled “Pin 1”. Because

there is not a second side tab labeled “Pin 2” we know only one pin has been added to the

system.

All of the information in the Calibration and Input tabs applies to Pin 1.

Figure 28 - Load Pin Setup - Single Pin

When a second load pin has been added a second side tab appears. The new tab is labeled

“Pin 2”. The currently selected load pin has a white background. In Figure 29 Pin 1 is

selected. The information in the Calibration and Input tabs applies to Pin 1.

23

Figure 29 - Load Pin Setup - Two Pins - Pin 1 Selected

In Figure 30 Pin 2 is selected. The information in the Calibration and Input tabs applies to

Pin 2.

Figure 30 - Load Pin Setup - Two Pins - Pin 2 Selected

6.4.1.3 Add Load Pin

To add a pin to the system, select the Add Pin button from the Load Pin Setup context

menu.

When a pin is added the pin does not have an input selected and no calibration points

exist for the pin.

6.4.1.4 Input Tab

Use the input tab of the load pin setup screen to see the currently selected input and

change the selected input. See Section 5 for more information on how to use this screen.

The information on the input tab applies to the currently selected load pin.

24

6.4.1.5 Calibration Tab

The calibration tab of the load pin setup screen displays the currently entered calibration

points. Also it provides buttons to add new calibration points and delete existing points.

Figure 31 illustrates the calibration tab before any calibration points have been entered.

Figure 31 - Load Pin Setup - Calibration Tab

In Figure 32 the calibration tab is illustrated with several calibration points entered. The

points in the table are for illustration only and are not necessarily the calibration points to

be used on a unit. Note that when there are more points in the list than can be displayed

on the screen, there will be a scroll bar on the right of the calibration point list.

The Add New Point button is only enabled if there are less than 15 points in the list. The

delete button is only enabled when a point is selected. Touch on a point in the list to

select it.

Figure 32 - Load Pin Setup - Calibration Tab with Points

25

6.4.1.6 Add Load Pin Calibration Point

Touch on the Add Point button to add a calibration point to the currently selected pin.

Refer to Section 4.1 - Add Calibration Point (Page 12) for instructions on adding

calibration points.

When 15 calibration points already exist the Add Point button will be disabled.

6.4.1.7 Delete Existing Calibration Point

To delete an existing calibration point, touch on the row of the calibration point to be

deleted in the calibration point list. This will select the point to be deleted. Press the

delete point button, read and acknowledge the confirmation screen.

6.4.1.8 Delete Load Pin

Select the pin to be deleted using the Pin Selection buttons on the left of the Load Pin

Setup menu. From the context menu press the Delete Pin button. Read and acknowledge

the confirmation screen.

When a pin is deleted from the system the calibration table is cleared, the input is made

available for use by other sensor setup menus and the pin is removed from the system.

Note: Once a pin has been deleted the information deleted with the pin cannot be

recovered.

6.4.2 Load Pin Status

The top section of the Weight Display Configuration menu provides the status of

configured load pins. There is a button for each pin which may be configured. These

buttons are called the pin status selection buttons. The pin status selection buttons are

labeled Pin 1 and Pin 2. Below the pin status selection buttons is an area where messages

related to the state of the selected pin will be displayed; this is referred to as the pin

status.

When no pins have been added to the system or all existing pins have been deleted both

buttons will be gray. The pin status below the buttons will read “NO PINS

CONFIGURED”.

After a pin has been added to the system one of the pin status selection buttons will

appear with black text. When two pins have been added to the system both buttons will

appear with black text.

The pin status information applies to the selected pin. If the input has not been selected

for the sensor the pin status will read “INPUT NOT CONFIGURED”. When the input

has been selected for a sensor the pin status area will display the signal currently being

received from the load pin.

26

Figure 33 illustrates the Load Pin Status area with no load pins configured. Note that

neither Pin 1 nor Pin 2 is selected and the text for each pin is grayed out. The text in the

pin status area reads “NO PINS CONFIGURED”.

6.4.3 Zero Weight

In the center of the Weight Display Configuration screen is a button labeled “Zero

Weight”. This button begins the process of applying an offset to the weight display. An

offset is used to hide forces associated with the system that are not applied to the tubing.

To zero the weight display, touch the Zero Weight button. After touching the Zero

Weight button a confirmation screen will be displayed. This screen displays information

regarding the action that will be taken on confirmation. Dependent upon the conditions of

the injector, reel and tubing this confirmation will display different messages. Always

carefully read the zero weight confirmation.

27

To confirm that the offset should be applied press the Confirm button from the context

menu. Alternately to cancel the Zero Weight process, press the Cancel button.

Figure 37 illustrates the Zero Weight Confirmation screen under normal conditions. The

weight to be offset was less than 2,000 pounds and the depth was not more than 50 feet.

Figure 37 – Zero Weight Confirmation - Normal

Figure 38 illustrates the Zero Weight Confirmation screen under the conditions that the

offset to be applied is greater than 2000 pounds. A large deviation from zero at the

surface may cause problems during the job if an offset is used to temporarily cover up a

problem. Verify all equipment is ready for operation before proceeding.

Figure 38 - Zero Weight Confirmation - Large Offset

Figure 39 illustrates the Zero Weight Confirmation screen under the conditions that the

depth was greater than 50 feet. Attempting to zero the weight with tubing in hole may

cause the weight display to hide some the weight of some tubing in the hole. Additionally

an offset sampled with tubing in hole may not be accurate due to well conditions.

7 Depth & Speed Display The Depth & Speed display is the middle (vertically) one third of the Constantly Visible

section of the screen. The Depth & Speed display provides the current depth, speed and

direction of tubing movement. Also provided by the Depth & Speed display is the status

of the speed and depth limiting systems.

29

This section discusses general capabilities of the Depth & Speed display system in

FLECS CT and describes the interface used for managing all aspects of the Depth &

Speed display.

Figure 41 – Depth & Speed Display

7.1 FLECS CT Depth Measurement

The FLECS CT system measures depth using an encoder. The encoder is connected to a

wheel which contacts the tubing. The FLECS CT system is capable of using encoders of

different resolutions and wheels of different circumferences.

The Halliburton standard encoder has a resolution of 500 pulses per revolution. The

Halliburton standard wheel has a circumference of 2.000 feet.

7.2 Current Depth

The large number in the top half of the Depth & Speed display indicates the current

depth. Depth increases as the direction of tubing movement is in hole. The depth will

become negative when tubing moves above the point at which the depth was set to zero.

The unit the depth is currently displayed in is indicated in the above and right of the

current depth.

The depth is not displayed if the encoder does not have a valid calibration.

In Figure 42 the current depth is circled by a blue oval. The current units indicator is

enclosed in a green triangle.

Figure 42 – Depth & Speed Display – Depth & Units Highlighted

30

7.3 Speed

The speed indicator is in the lower right corner of the Depth & Speed display. The speed

is always a positive number. The direction of pipe movement is indicated by the

Direction Indicator.

At speeds less than 10 ft/min in either direction the speed will be displayed to one-tenth

of a foot per minute accuracy. When the speed is greater than 10 ft/min the speed is

displayed to one foot per minute accuracy.

7.4 Direction Indicator

The direction of tubing movement is indicated by a graphic just under the speed label in

the lower left corner of the Depth & Speed display. This is called the Direction Indicator.

When the tubing is moving out of hole the Direction Indicator appears as an upward

pointing arrow. In Figure 43 the Direction Indicator is highlighted by a red rectangle and

the direction of tubing movement is out of hole.

Figure 43 – Depth & Speed Display – Out of Hole

When the tubing is moving in hole the Direction Indicator appears as a downward

pointing arrow. In Figure 44 the Direction Indicator is highlighted by a blue oval and the

direction of movement is in hole.

Configuration screen opens the Limiting System configuration menu. See Section 9 -

Limiting System (Page 44) for Limiting System documentation.

7.6.7 Close

In the context menu for the Depth & Speed Display Configuration screen is a button

labeled Close. This button closes the Depth & Speed Display Configuration menu. When

the Depth & Speed Display Configuration menu is closed the Custom Inputs will be

displayed.

8 Pressure Display The pressure display is the bottom one third of the constantly visible section of the

screen. The pressure display provides the tubing and wellhead pressures. In Figure 55 the

pressure display is highlighted in a red rectangle.

37

This section discusses the general capabilities of the pressure display and describes the

interface used for managing all aspects of the pressure display.

Figure 55 – Pressure Display

8.1 FLECS CT Pressure Measurement

The FLECS CT system measures pressure using pressure transducers. The standard

pressure transducer is a 0 – 15,000 PSI transducer with a 4-20 mA output. The FLECS

CT system is capable of using analog output pressure transducers with other pressure

ranges, up to 20,000 PSI.

8.2 Tubing Pressure

The top half of the pressure display provides the tubing pressure. The current pressure is

displayed in large black text in the top half of the pressure display. The selected unit for

the tubing pressure is displayed above the tubing pressure on the right side of the pressure

display.

In Figure 56 the tubing pressure is enclosed in a blue oval. The selected unit is

highlighted by a green triangle.

38

Figure 56 – Pressure Display – Tubing Pressure

8.3 Wellhead Pressure

The bottom half of the pressure display provides the wellhead pressure. The current

pressure is displayed in large black text in the bottom half of the pressure display. The

selected unit for the wellhead pressure is displayed above the wellhead pressure on the

right side of the pressure display.

In Figure 57 the wellhead pressure is enclosed in a red rectangle. The selected unit is

highlighted by a blue oval.

Figure 57 – Pressure Display – Wellhead Pressure

8.4 Pressure Display Configuration

A touch in the pressure display opens the Pressure Display Configuration menu. The

Pressure Display Configuration screen is displayed in the context dependent section of

the screen. Figure 58 illustrates the Pressure Display Configuration menu.

Configuration of the tubing and wellhead pressure transducers use similar screens. Only

configuration of the tubing pressure transducer is illustrated in this document.

39

Figure 58 – Pressure Display Configuration

8.4.1 Tubing Pressure Transducer Status

Just below the Tubing Pressure text at the top of the screen the tubing pressure transducer

status is displayed. In Figure 59 the Tubing Status area is circled by a blue oval.

Figure 59 – Pressure Display Configuration – Tubing Status

40

Figure 60 – Pressure Display Configuration – Tubing Display Unit

8.4.3 Tubing Pressure Zero

In the top right of the Pressure Display Configuration menu is a large button labeled

“Zero”. This button is used to apply an offset to the tubing pressure. The zero button is

highlighted by a green triangle in Figure 61.

Figure 61 – Pressure Display Configuration – Zero

Before performing the zero process for a pressure transducer ensure that the transducer is

exposed to atmospheric pressure. Touch on the zero button to begin the zero process. The

Confirm Zero Transducer screen will be displayed indicating what action is going to take

place upon confirmation. The Confirm Zero Transducer screen is illustrated in Figure 62.

Read the message carefully. To confirm and execute the zero process, press Zero

Pressure. To cancel press the Cancel button.

41

Figure 62 – Confirm Zero Pressure

A safety feature is integrated into FLECS CT which prevents the pressure display from

differing from the actual pressure on the transducer because of a large offset. This

condition could occur if the transducer was exposed to pressure when a zero process was

executed. This feature also prevents the zero process from being executed if the

transducer signal is below the reasonable operating range for the transducer.

When the signal from a pressure transducer is more than 4.50 mA the Cannot Zero

Transducer message will be displayed. The only option is to touch Cancel and correct the

condition causing the high transducer signal. Figure 63 illustrates the message displayed

under these conditions.

Figure 63 – Cannot Zero Pressure – High Signal

When the signal from a pressure transducer is less than 3.5 mA but greater than 0.5 mA

the Cannot Zero Transducer message will be displayed. The only option is to touch

Cancel and correct the condition causing the low transducer signal. Figure 64 illustrates

the message displayed under these conditions.

42

Figure 64 – Cannot Zero Pressure – Low Signal

When the signal from a pressure transducer is less than 0.5 mA Cannot Zero Transducer

message will be displayed. The only option is to touch Cancel and correct the condition

causing the low transducer signal. Figure 65 illustrates the message displayed under these

conditions.

9 Limiting System The Limiting System monitors several aspects of the coiled tubing unit. When conditions

exceed a predefined threshold the CT unit is stopped.

The Limiting System consists of three components. The first component is the set of

sensors used to measure the state of the CT unit. The load pin(s) are used to measure the

state of the forces applied to the tubing. The encoder is used to measure the depth, speed

and direction of the tubing.

The second component of the Limiting System is the FLECS controller. The FLECS

controller observes the state of the system using the sensors described above. Ten times

per second the FLECS controller evaluates each limit to determine if the state of the CT

unit is still within the limits established by the operator.

45

If the FLECS controller determines the CT unit has exceeded the limits the third

component of the Limiting System is used to stop the injector. A pair of electrically

controlled valves simultaneously stop the injector and set the injector brake.

The Limiting System is designed to quickly react to an emergency situation. The

Limiting System is not designed to reduce operator workload. The injector experiences

high loads when rapidly stopping the motion of tubing. Configuration of the Limiting

System resulting in frequently exceeded limits will reduce the lifespan of some

components of the injector.

The Limiting System consists of six individual limits. The operation of each individual

limit is described in Sections 9.2 and 9.3.

9.1 Limit States

The way the FLECS CT controller conveys information about each limit is by displaying

the state of the limit. Each of the limits moves between one of the five states as a result of

actions taken by the operator and signals received by sensors.

The remainder of this section describes what each of the five states means and how the

state is illustrated on the FLECS display. Also discussed are the actions the FLECS CT

controller takes when a limit is in the state.

The information in this section is generalized. For details specific to each limit see the

section discussing the relevant limit.

The state of each limit is illustrated in the constantly visible display related to the limit. In

each section describing a limit state an illustration of each limit in the described state is

provided.

9.1.1 Off

The Off state indicates the operator has turned the limit off. While off the limit state will

be illustrated with black text on a red background. The text for the limit will contain the

word “Off”.

The FLECS CT application does not evaluate the limit when in the off state. The FLECS

controller will not automatically turn a limit on under any conditions. Limits must be

turned on by the operator.

46

Figure 69 – All Limits Off

9.1.2 On

The On state will be illustrated with green text on a white background. The text for the

limit state will contain the word “On”.

The FLECS CT application monitors the sensors associated with the limit. The signal

from the sensor indicates that the limit is within the currently established threshold.

Figure 70 – All Limits On

47

9.1.3 Warn

The Warn state will be illustrated with black text on a yellow background. The yellow

background will fill the entire constantly visible display associated with the limit. The

text for the limit state will contain the word “Warn”.

The FLECS CT application monitors the sensors associated with the limit. The FLECS

CT application has determined that the limit is close to the established threshold. Action

should be taken to prevent the limit from tripping.

Not all limits will enter the warning state before enter the tripped state. If the conditions

of the CT unit are changing rapidly even limits with a warning state may move directly

from On to Tripped without warning.

Figure 71 – Warn State

9.1.4 System Disabled

The System Disabled state is illustrated with black text on a white background. The text

for the limit state will contain the word “Off”.

The FLECS CT application monitors the sensors associated with the limit. The FLECS

CT application has determined that a rapid shutdown of the injector would be unsafe

under current conditions. The limit will not trip even if the threshold for the limit is

exceeded.

All limits will exit System Disabled state regardless of the speed if the depth is less than

100 feet.

If the limit is turned on the limit will be restored to On or Warn state when system

conditions indicate that a rapid shutdown of the injector is safe. If the FLECS CT

48

application determines that the potential consequences of a rapid shutdown of the injector

are less serious than not taking this action the FLECS CT application will restore the

limits to the On or Warn state.

All limits which are on when a limit system test begins will be set to System Disabled

state until the test is ended.

Figure 72 – System Disabled State

9.1.5 Tripped

The Tripped state is illustrated with black text on a red background. The red background

will fill the entire constantly visible display associated with the limit. The text for the

limit state will contain the word “Limit”.

The FLECS CT application determined that the threshold for the limit has been exceeded.

The FLECS CT application uses the limiting system valves to dump injector pressure and

set the injector brake.

See Section 9.5 - Resetting Tripped Limits (Page 61) for details on resetting tripped

limits.

49

Figure 73 – Tripped State

9.2 Weight Limits

There are three limits related to the weight. This section provides details on the operation

of each limit.

Each of the Weight Limits requires all components of the Load Limiting system to be

operating correctly to be effective.

9.2.1 Pull Limit

The Pull Limit compares the current weight to a threshold set by the operator. When the

weight is within 1500 pounds of the threshold the limit will enter Warn state. When the

weight exceeds the threshold the limit will enter Tripped state.

The Pull Limit will enter System Disabled state if the out of hole speed exceeds 50 feet

per minute. When the out of hole speed drops below 50 feet per minute the Pull Limit

will exit System Disabled State. When the depth is less than 100 feet the Pull Limit will

exit System Disabled State regardless of tubing speed.

FLECS CT will not allow the Pull Limit to be enabled if the load pin configuration is

invalid or if the primary encoder has not been configured. See Section 6.4.1 - Load Pin

Setup (Page 21) for more information on configuring load pins. See Section 7.6.1 -

Encoder Setup (Page 32) for more information on the primary encoder setup.

All calculations related to the Pull Limit are performed in pounds regardless of the

display unit.

50




9.2.2 Snub Limit

The Snub Limit compares the current weight to a threshold set by the operator. When the

weight is within 1500 pounds of the threshold the limit will enter Warn state. When the

weight exceeds the threshold the limit will enter Tripped state.

The Snub Limit will enter System Disabled state if the out of hole speed exceeds 50 feet

per minute. When the out of hole speed drops below 50 feet per minute the Snub Limit

will enter the relevant state based on the comparison of current weight to Snub Limit

threshold. When the depth is less than 100 feet the Snub Limit will exit System Disabled

State regardless of tubing speed.

FLECS CT will not allow the Snub Limit to be enabled if the load pin configuration is




All calculations related to the Snub Limit are performed in pounds regardless of the

display unit.




9.2.3 Tag Limit

The Tag Limit monitors the rate of change of the current weight. If the weight changes by

more than 800 pounds in one tenth of a second the Tag Limit enters the Tripped state.

There is no Warn state for the tag limit.

The Tag Limit will enter System Disabled state if the out of hole speed exceeds 50 feet

per minute. When the out of hole speed drops below 50 feet per minute the Tag Limit

will enter the relevant state based on the comparison of current weight to Tag Limit

threshold. When the depth is less than 100 feet the Tag Limit will exit System Disabled


FLECS CT will not allow the Tag Limit to be enabled if the load pin configuration is




All calculations related to the Tag Limit are performed in pounds regardless of the

display unit.

51




9.3 Depth & Speed Limits

There are three limits related to the depth and speed. This section provides details on the

operation of each limit.

Each of the Depth & Speed Limits requires all components of the Load Limiting system

to be operating correctly to be effective.

9.3.1 Pull Out Limit

The Pull Out Limit monitors the current depth and speed. The Pull Out limit will enter

System Disabled state when the direction is out of hole and the speed exceeds 50 feet per

minute.

The Pull Out Limit exits System Disabled state regardless of speed when the depth is less

than 100 ft.

The Pull Out Limit enters the Warn state under two conditions. The Warn state will be

entered when the time to zero depth is less than sixty seconds and the direction is out of

hole. The Warn state will also be entered when the depth is 25 feet or less and the

direction is out of hole, regardless of the speed.

The Pull Out Limit enters the Tripped state under two conditions. The Tripped state will

be entered when the time to zero depth is less than 10 seconds and the direction is out of

hole. The Tripped state will also be entered when the depth is 10 feet or less and the

direction is out of hole, regardless of the speed.

FLECS CT will not allow the Pull Out Limit to be enabled if the load pin configuration is







FLECS CT will not allow the Pull Out Limit to be enabled if the load pin configuration is




9.3.2 Speed Out of Hole Limit

The Speed Out of Hole limit compares the current speed to a threshold set by the

operator. When the direction is out of hole and the speed is within 15 feet per minute of

52

the threshold the limit will enter Warn state. When the direction is out of hole and the

speed exceeds the threshold the limit will enter Tripped state.

The Speed Out of Hole Limit will enter System Disabled state if the out of hole speed

exceeds 50 feet per minute. When the out of hole speed drops below 50 feet per minute

the limit will enter the relevant state based on the comparison of current speed to limit

threshold. When the depth is less than 100 feet the Speed Out of Hole Limit will exit

System Disabled State regardless of tubing speed.

FLECS CT will not allow the limit to be enabled if the load pin configuration is invalid

or if the primary encoder has not been configured. See Section 6.4.1 - Load Pin Setup

(Page 21) for more information on configuring load pins. See Section 7.6.1 - Encoder

Setup (Page 32) for more information on the primary encoder setup.

All calculations related to the Speed Out of Hole Limit are performed in feet per minute

regardless of the display unit.




9.3.3 Speed In Hole Limit

The Speed In Hole limit compares the current speed to a threshold set by the operator.

When the direction is in hole and the speed is within 15 feet per minute of the threshold

the limit will enter Warn state. When the direction is in hole and the speed exceeds the

threshold the limit will enter Tripped state.

The Speed In Hole Limit will enter System Disabled state if the out of hole speed exceeds

50 feet per minute. When the out of hole speed drops below 50 feet per minute the limit

will enter the relevant state based on the comparison of current speed to limit threshold.

When the depth is less than 100 feet the Speed In Hole Limit will exit System Disabled


FLECS CT will not allow the limit to be enabled if the load pin configuration is invalid

or if the primary encoder has not been configured. See Section 6.4.1 - Load Pin Setup

(Page 21) for more information on configuring load pins. See Section 7.6.1 - Encoder

Setup (Page 32) for more information on the primary encoder setup.

All calculations related to the Speed In Hole Limit are performed in feet per minute

regardless of the display unit.




53

9.4 Limit Setup

The Limit Setup menus can be accessed with two different methods. Both the Weight

Display Configuration and Depth & Speed Display Configuration menus have a Limiting

Setup button. See Sections 6.4.5 (Page 28) and 7.6.6 (Page 36) for more information on

accessing the Limit Setup screen.

There are four sections in Limit Setup menu. The sections of the Limit Configuration

menu are referred to as “tabs.” Each tab of the Limit Setup menu provides options for

configuration a specific part of the Limiting System.

Figure 74 illustrates the tabs with Output tab currently selected. The currently selected

tab has a white background. The other two tabs are illustrated with a gray background.

To change to another tab touch the desired tab. Not all tabs are visible on the screen. Use

the left and right arrow buttons to scroll through the available tabs.

FLECS CT will not allow changing from the output tab until the digital output has been

9.4.2 Weight Tab

The Weight Tab is used to enable or disable the Pull, Snub and Tag limits and to set the

thresholds for the Pull and Snub limits. The Weight tab is divided into three sections, one

for each of the limits. The labels on the left side of the screen indicate which limit the

information displayed in the section applies to. Figure 76 illustrates the Weight tab.

Notice the three blue squares to the right of each limit name. Each of these is called a

checkbox. A checkbox is much like an on off switch. When a limit is turned on a check

mark will appear in the middle of each box. In Figure 76 the Snub Limit is on because

there is a check mark in the box. When a limit is off there is no check mark in the

checkbox. In Figure 76 the Pull Limit is off. To change the state of a check box touch on

the checkbox.

10.1 Shutdown

Prior to turning the power to the FLECS controller off the Shutdown process must be

performed. The shutdown process allows the FLECS CT application to properly prepare

for the power to be switched off. Failure to perform a System Shutdown prior to

switching the power off can cause the FLECS CT application to malfunction and cause

damage FLECS hardware.

To begin the System Shutdown process press the System Shutdown button on the System

Menu.

After a touch on the System Shutdown button the FLECS CT application displays a

confirmation dialog. When the FLECS CT application begins the shutdown process the

FLECS Controller discontinues any services it normally provides.

65

To cancel the System Shutdown process touch on the Cancel button. To confirm the

System Shutdown process touch on the Shutdown button.

The System Shutdown takes up to a minute to complete. It is critical that the power to the

FLECS controller never be interrupted while the FLECS CT application is shutting down.

Interruption of the power while shutting down can cause the FLECS CT application to

become inoperative and damage FLECS hardware. When the System Shutdown process

begins the FLECS display will indicate that the Shutdown Process is in progress.

Figure 90 – System Shutdown In Progress

After the System Shutdown process completes FLECS CT will show the message

illustrated in Figure 91. Do not turn off the power to the FLECS controller until this

message is displayed.

The first of two KIPS calibration menus will be displayed. The objective of these two

screens is to use the up and down arrows to move the needle on the KIPS gauge until it

rests on the target weight.

The target weight is surrounded by a blue oval in Figure 94. This is the weight the needle

on the KIPS gauge should point to before continuing.

67

The up arrows make the needle move in the clockwise direction, towards a higher pull

value. The down arrows make the needle move in the counter-clockwise direction,

towards a higher snub value.

The arrows on the left side of the menu make the needle move a large amount with one

touch. Use these two arrows to get the needle close to the target weight. The arrows on

the right side of the menu move the needle a small amount. Use these arrows to make

small adjustments to the needle until it rests on the target weight.

When the needle is as close to the target weight as possible touch on the Next button to

move to the second KIPS calibration menu. Use the up and down arrows to move the

needle to the target weight. Then touch the Done button to complete the process.

12 Custom Inputs Custom Inputs are used for displaying inputs from additional sensors connected to the

FLECS controller. FLECS CT supports four types of sensors: Current (4-20 mA) inputs,

frequency inputs, magnetic pickup inputs, and encoders. The FLECS application can also

display the totalized values for frequency, mag-pickup and encoder inputs.

When all menus and context dependent menus are closed, the context dependent section

of the screen is divided into six parts. The operator can configure each of the six parts as

any of the four supported custom input types. The red rectangle encloses the six custom

inputs in Figure 102.

Figure 102 - Custom Inputs Highlighted

When configured, the Custom Input will display either three or six information fields

related to the Custom Input. In Figure 103 the Custom Input on the left has been

configured as a Current and the units have been selected as MPa. The operator has

configured the screen on the right as a Total, so it includes a rate in the upper half and the

totalized rate in the lower half.
