Patent

CA 2182535

A one-trip whipstock milling system is disclosed which allows for setting of a packer or plug which is run in as part of the bottomhole assembly, in conjunc- tion with orientation instrumentation, a whipstock, and a one-trip milling system connected to the whipstock. The assembly is run-in the hole together and inserted to the desired depth. With the orientation of the whipstock known from the down- hole instrumentation, the preferred embodiment involves pressurization of the well- bore to actuate the packer assembly. Having set the packer at the proper orienta- tion and depth, the milling immediately begins and continues in a continuous effort until the window is fully milled, at which point the milling equipment and orienta- tion equipment are withdrawn from the wellbore.
