Multi Lateral Definitions Level I Open Hole Side Track / Casing Landed Above Laterals / No Casing or Liners in Legs / All Legs Are Open Hole Side Tracks Below the Mother Bore Level II Cased and Cemented Mother Bore / Open Hole Lateral(s) From Mother Bore / Liners Run in All Laterals / Liners Are Not Cemented and Not Supported By Liner Hangers / Liners are Dropped Off In Open Hole
Multi Lateral Level Definitions Level III Cased and Cemented Mother Bore / Open Hole Lateral Leg Number One Below Mother Bore / No Liner in Lower Leg / Open Hole Lateral Leg Number Two From Mother Bore With Liner In Place Supported or Hung in Mother Bore Level IV Cased and Cemented Mother Bore / Open Hole Lateral Leg Number 1 Below Mother Bore Has Liner That Is Cemented and Supported By Liner Hanger / Open Hole Leg Number Two and All Additional Legs Have Liner Cemented and Tied Back to Mother Bore / Leak Off Pressure Integrity at Junction
Multi Lateral Level Definitions Level V Same Configuration as a Level IV Junction / Pressure Integrity is Achieved With Completion Equipment Level VI A Down Hole Splitter Is Used To Create To Create Two Distinct Wells That Are Drilled, Cased and Completed From a Single Surface Conductor or Mother Bore / Full Pressure Integrity in Both Legs
ML System Overview - allows several exits from original mother bore (typically three or four exits / tri or quad laterals from one Latch In Coupling) - system components are simple design and economical - exits are achieved through composite / fiberglass or steel casing - exits are achieved using conventional bits through composite casings or one trip tri mills through steel casings - reduction of consumable costs by re-use of anchors and lower whipstock assemblies - reduction of total trips - ability to re-orient / re-set deflectors in windows for positive access to all laterals - all windows can be oriented vertically and directionally from one single datum landing point - several components are reusable lowering direct system cost - the system incorporates simple proven whipstock and casing exit technology - the liner is run, released and the whipstock assembly recovered in one trip on some Level II ML operations (typically CBM operations)

Latch in Coupling and Latch in Sub The Command Fishing Services Inc. Flush Type Latch In Orientation Coupling and Latch In Sub allow the operator to design a multi lateral well bore from vertical, high angle or horizontal well bores. The system incorporates a flush ID mule shoe latch in coupling that is installed in the casing string just below the exit depth(s). There can be multiple flush type latch in couplings installed in the casing string if multiple exits are required at substantially different depths. A single latch in coupling can be installed and multiple exits can be achieved by spacing out the latch in assembly to the required depths. Once the flush type latch in coupling is cemented in place an initial run is made to gauge, scrape and brush the casing string to clean up and remove any cementing debris, the latch in sub is latched into the coupling and a survey is taken to establish the direction of the latch in coupling. Upon completion of the clean up / survey run all the subsequent exit operations can be achieved by spacing out and orienting the latch in sub and whipstock assembly at surface to achieve the desired depth and exit direction. The first whipstock assembly is made up with the latch in sub and required space out installed, the whipstock is oriented at surface (the whipstock face is off set to the latch in sub) to achieve the proper exit direction when the latch in sub is latched into the flush type latch in coupling. The whipstock assembly is run in the well, the whipstock assembly is latched into the flush type coupling and the running / milling tools are sheared off the whipstock. The window is milled or drilled out as required and the lateral is completed.
Latch in Coupling and Latch in Sub The whipstock assembly is then recovered and the next exit is achieved by spacing out and re- orienting the whipstock assembly to the required exit depth and direction. The process is repeated for all addition exits. Exit operations can be done through traditional steel casings with milling tools or through Command Fishing Services Inc. Composite Exit System where a composite casing is used at the exit depth and exit operations can be accomplished using mills or standard PDC bits and drilling assemblies.

Typical Operations Sequence For A Two Leg Level IV Well Profile In 7” OD Casing Establishing Leg Number One 1) Drill 17.1/2” surface hole. 2) Run and cement 13.3/8” casing. 3) Drill 12.1/4” hole. 4) Run and cement 9.5/8” casing. 5) Drill 8.1/2” vertical hole, continue drilling 8.1/2” build section to approximately 90 degrees hole angle in the target formation. 6) Run 7” steel casing as required for space out to lateral exit depth. 7) Install Command Fishing Services Inc. Latch in Coupling and continue with steel casing to surface (position latch in coupling approximately five meters below the exit depth of lateral leg number two). 8) Circulate, clean up and cement the 7” casing. 9) Wait on cement. 10) Pick up directional drilling assembly. 11) Run in and drill horizontal leg number one out the bottom of the 7” casing. 12) Pull out with directional drilling assembly. 13) Make up standard liner assembly with standard guide shoe, float collar, 4.1/2” liner, liner setting collar, PBR (Polish Bore Receptacle) liner hanger packer. 14) Run and position 4.1/2” liner as required with overlap into the 7” casing.
