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.
