Level IV Multi Lateral Whipstock
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)
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
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.
