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 reorienting 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.
