Abstract
A technique facilitates sidetracking by eliminating one or more trips downhole. The technique comprises delivering a sidetracking system downhole into a wellbore, and utilizing a component of the sidetracking system to grip a wall of the wellbore. The sidetracking system may comprise a whipstock assembly and a running/stinger assembly in which the stinger assembly is designed for disconnection from the whipstock assembly after delivery downhole. After disconnecting the stinger assembly, the sidetracking system enables delivery of cement slurry down through the stinger assembly to form a cement plug at a desired location.
