Well ControlThe Basic Concept, in 5 Minutes

1. While drilling, mud is used to "sit on the formation pressuresencountered

2. Some formations encountered have abnormally high pressure 3. The BOP is used to temporarily retain pressure in the well. 4. .while mud is mixed to a heavier density to "sit on " the higher pressure

encountered 5. Need to pump the heavier mud down to the bottom of the well to "sit on"

the pressure while at the same time allowing only some of the light mudout of the well bore



Nomenclature, the LMRP and BOP Stack

1. The Lower Marine Riser Package (LMRP) is actually on the bottom of the

riser when it is disconnected 2. Blowout Preventer (BOP) stack refers to the bottom section (lower half)

and some people use it to refer to the stack in addition to the LMRP

BOP STACK



Overview of Drilling the Well

1) WellheadsDue to the unconsolidated formations on the sea bottom the foundation for thesubsea BOP stack must be constructed in progressive manner. The tool used tobuildup the foundation are successive strings of casing attached below the subseawellhead. The table below identifies the typical casing strings and holes drilled inorder to run these casing strings :

2) Installation Of 30" CasingThe drilling process begins with installation of the 30" casing. There are 2 basicmethods to spud a well - drill-in or jet-in the 30" casing. The method depends uponthe operator's drilling procedures and the hardness of the shallow formations.

a) Drill-In 30" Casing-In areas with hard, shallow sediments, a 36" hole is drilled and the 30" casing isrun and cemented. The first step in the drilling process is to set the temporaryguide base (TGB) this is some times called the mud mat. It has a large undersurface to help support the weight of the 30" casing and serves as anattachment point for the guidelines. After setting the TGB on the rigs spiderbeams and attaching guidelines, the TGB is run and landed on the seafloor withdrillpipe and a J-slot running tool. A utility tool or more often soft rope is thenused to center the 36'" bit between the guidelines while lowering it to the seabed. Drilling is conducted with returns to the sea floor. The 30 casing is made-up with the 30" wellhead housing on the top joint. As the 30" casing is runthrough the permanent guide base (PGB), supported on the spider beams, the30" housing is landed in the PGB and latched into it. The PGB and 30"structural pipe are then lowered on drillpipe to the ocean floor where the casing



is stabbed through the TGB and run in the hole until the gimbal on the PGBbottoms out on the TGB cone. The 30" casing is then cemented with returns tothe sea floor.

b) Jet-In 30" Casing-In areas where shallow sediments are soft, such as the Gulf of Mexico, the 30"casing is jetted in place. Generally, 150 to 300 ft of 30 casing is made-up with a30" wellhead housing welded on the last joint. The 30" cam actuated orthreaded running tool is made-up with all plugs removed into the 30" wellheadhousing. A bumper sub is usually placed directly above the 30" running tool.The 30" pipe is lowered through both the PGB and mud mat located on thespider beams. The 30" housing is landed and locked into the PGB. The PGB ispicked up so the mud mat can be attached with 4 - 8 ft posts to elevate the 30"wellhead out of the jetted cuttings. Guidelines are attached to the mud mat andthreaded through the PGB guideposts. With this assembly still resting on thespider beams, a jetting string is made-up and run inside the 30" casing. The jetstring consists of a mud motor backed up with stabilizers and drill collars. Thebit is usually located 12" to 18" up inside the bottom of the 30" casing.

c) Mud Mat-After the jetting string is run inside the 30" casing and the 30" housing runningtool is engaged, the entire assembly is run to the sea bed to begin the jettingoperation. The jetting operation is stopped when the mud mat lands on the seafloor and positive string weight is observed. The 30" housing running tool isthen released and retrieved along with the jetting string. Cementing is generallynot required as formation friction is sufficient to keep the 30" casing in place.

3) Installation of 20" Casing and High Pressure WellheadDrilling the hole for the 20" casing begins with running a 26" bit through the PGBand into the 30" casing.

a) Drilling Without Returns to the Surface-Drilling returns are usually taken onto the ocean floor unless conditions dictatethat returns must be conducted up to the rig. The bit is guided into the 30"casing by a utility guide frame or with rope and shackles. In areas susceptible toshallow gas, the hole may be drilled initially with a small diameter pilot bit andthen enlarged to 26". With a smaller diameter hole, less gas is allowed toescape if it should be encountered.

b) Drilling With Returns to the Rig-In situations requiring returns to the surface, such as when drilling on a multiwell template, a 30" pin connector is used. This is also called a 30" latch head.The 30" pin connector connects on to the bottom joint of riser and is lowered on



to the 30" wellhead where it latches. Dump valves are usually placed on the 30"latch head to allow flooding of the riser if it should be loaded with gas during akick. Due to the lack of suitable foundation under the 30" casing, the well cannot be closed in if a kick is encountered. The diverter is closed and the wellallowed to flow until it depletes itself. Diverting a kick is probably one of themost dangerous operations on a drilling rig. An alternate action is to disconnectthe pin connector rather than attempting to divert the kick. The 26" hole isdisplaced with gel-water and the bit pulled after the hole has reached therequired casing depth.

The 18 " 10,000 psi or 15,000 psi well head housing is installed on top of the20" casing. The wellhead is designed with load rings to land on and ribbedextensions to centralize it in the 30" wellhead. The wellhead is designed for therequired number of casing and tubing hangers to complete the well. Mostsystems allow the use of 3 or 4 hangers. The upper connection of the wellheadhousing is designed to latch the connector of the subsea blowout preventerstack. The Cameron wellhead and connector system use an AX gasket profile,while the Vetco system uses the VX connector gasket and Dril Quip uses the DXgasket. None of the gaskets are interchangeable.

The wellhead and 20" casing are lowered to the sea bed as an assembly withthe wellhead running tool on drill pipe latched into the wellhead. The shoe of the20" casing is guided into the 30" wellhead with breakaway guide arms or withrope and shackles. As the 20" high pressure wellhead lands in the 30" housing,it latches in place becoming rigidly attached to the 30" wellhead housing. The20" casing is cemented in place with returns taken to the sea floor.

After the 18 " wellhead is landed and cemented in place, the subsea BOPstack can be run and drilling the 17 " hole for 13 5/8" casing can commencewith the protection of a BOP stack.
