Designed as a one-trip system for sidetracking operations, the Cougar Drilling Solutions Whipstock is an innovative product engineered to reduce the risk and cost of launching open hole sidetracks.
A hydraulically set, one-trip system helps to avoid the costly time and fees associated with mechanical bottom-hole designs. Our anchor and slip design enhances and increases wall contact, reducing the likelihood of slipping or rotating downhole while milling. Simple but sophisticated engineering allows for inexpensive transition between cement or conventional, and cased versus open hole applications.

The side track system is comprised of four major components:
The running tool is used to isolate clean fluid in the tool assembly from the drilling fluid in the drill string.
The bi-mill is used to lower the whipstock assembly down the wellbore to the desired depth. Once the whipstock assembly is in place, the anchor can be set hydraulically, at which point the bi-mill can be sheared away from the whipstock assembly. This will allow milling operations to begin. After milling the window, the bi-mill can be tripped out of the wellbore and drilling operations can continue.
The shear sub can be used to lower the whipstock assembly into the wellbore instead of the bi-mill. In doing this, a mud motor assembly can then be used to drill off the ramp and continue drilling operations.
The deflection ramp is designed to direct the drill string in the desired direction and kickoff at the designated depth. The deflection ramp also makes it possible to achieve a smooth transition from a vertical to a horizontal wellbore.
The spacer sub is used to distance the anchor away from the window exit above. This will allow the anchor to stay secured in the undisturbed formation below the window exit.
The anchor is used to secure the upper assembly from any movement that might occur during drilling operations.
