Torque Wrench 10-100 Mobile Bucking Unit

1© 2006 Weatherford. All rights reserved.

Mobile Bucking Unit

• Designed for making up and breaking out joints of drill-pipe ranging from 2 ½ to 10inch in tool joint diameter.


World First

• Weatherford’s world first TW 10-100 MBU is operating for BHPBilliton’s Stybarrow campaign on the Atwood Eagle.

• It was designed for BHPB as they saw a need to make up BHA assemblies offline in a safe environment on the pipe deck.

• Currently the unit is making up BHA to 70 feet in length

• Not solely used for BHA, it currently also makes up tools such as:

– Cement head stand, ready to rack back in derrick

– Well head running and retrieval tools

– B.O.P test plugs

– TIW valves

– X-overs and Jetting tools


MBU Key Features

• The equipment is stand alone and only requires a 440V power connection.

• It is transportable and is designed to be lifted on/off the rig when operations dictate. DNV certified

• The Tong is capable of producing 100 000ft/lbs of torque.

• Spinner is capable of a producing 3000ft/lbs of torque.

• Weatherford’s new 3 jaw clamping system, eliminating jaw slip and damage to tool joints.

• What separates this from other Bucking or CAM Units.

– Mobility

– Has the advantage of being loaded and unloaded from above, so its perfect for areas where you are tight on space.


Reliability

• Reliability– The 4 main components: Torque Wrench, Spinner, Electric Power Unit and

Control Cabinet are all components that are field proven on other Weatherford equipment.

– Designed and manufactured by Weatherford in Germany

– Backed by Weatherford Australia’s local operational and technical assistance.

– Currently 7 trained operators in Australia

– Supported by Weatherford’s QAQC program consisting of:

• Work Instructions

• Service Instructions

• Maintenance Registers and Spares Inventory

• Torque Connection Tracker sheet

• Level 1 and 2 competency training for operators

• Comprehensive Operators Manual


Safety

Safety:

– BHA tools can be loaded safely and securely with the use of a gantry or deck crane.

– It is operated by remote control allowing operator to maintain asafe distance from moving machinery.

– Emergency shut down devices fitted to the unit that allows quickshut down of hydraulics in the event of a spill.

– MBU base frame incorporates a spill containment area.

– Hazardous operations on the rig floor are reduced:

• Use of manual rig tongs

• Eliminates heavy stabilizers and 36” hole openers swinging around on tuggers.


Real Results

• Results from the Stybarrow campaign have been collated and the results are showing significant savings in critical path time.

• Comparisons were made to the previous well centre and it was calculated that on average each connection would save 15mins andeach Cement Head stand approx 60mins critical path time.

• It was also calculated that an additional 75% of this figure would be saved again in breaking out connections.

• The following slide shows the type and number of connections that were made in a 37 day period, when you add the 15hrs of makeup time saved with an additional 11hrs of breakout time the MBU hassaved more than 25hrs of rig time.

• Already saving one days rig rate of $350 000 USD.


Recorded Connections for Well Centre C


Comparison

• The previous example displayed how quickly 1 days operating costs can be saved using the MBU

• The following example shows the savings that have been gained from the beginning of the installation of the MBU

• Since this time the MBU has in excess of 300 connections for make up only. (period from 15th Oct 06 –6th Aug 07)

• The following slides display the number of total connections recorded as well as Cement Head assemblies.


Total Connections

• Based on this data the MBU has saved the StybarrowCampaign a total of 131hrs of critical path time in less than 10 months.

SAVING - 1.92 Million USD
