Abstract
A tool for running and retrieving a whipstock in a subterranean wellbore includes a tool body that has one end that is adapted to be connected to a pipe. The tool body includes a rail defined thereon that is adapted to selectively engage a slot defined on the whipstock. The pipe is in fluid communication with a bore defined in the tool body. The tool body includes a latch assembly for releasably connecting to the whipstock. The latch assembly is adapted to be moved when pressure is applied to the tool bore through the pipe thereby enabling the connection and disconnection of the latch assembly from the whipstock.
