An underreamer is designed to pass through a down-hole restriction, open up below the restriction, clean the hole to full gauge, and then close up for retrieval through the restriction. The restriction is typically in the production-tubing string in the form of nipple profiles, mandrels, and other completion accessories.An underreamer is designed to pass through a down-hole restriction, open up below the restriction, clean the hole to full gauge, and then close up for retrieval through the restriction.

ID concave, the whipstock can remain in place, eliminating the retrieval procedure andout the pilot hole so that the pipe can be pulled through. The pipe is usually pulled through from the side of the crossing opposite the drill rig. Pilot Hole Pilot hole reaming is the key to a successful directional drilling project. It is as important to an HDD pipeline as backfill placement is to an open-cut pipeline.A system and method facilitate sidetracking by eliminating one or more trips downhole. A sidetracking system includes a whipstock assembly and a stinger assembly. The stinger assembly has a stinger which extends at least partially through the whipstock assembly. The stinger is coupled to a sub of the sidetracking system by a releasable latch mechanism, such as a shear pin or collet.

There are two techniques to placeJun 30, 2011 Directional drilling can also be used to drill multilateral wells. Multilaterals are additional wells drilled from a parent wellbore as illustrated in Figure 1-11. Multilaterals can be as simple as an open hole sidetrack or it can be more complicated with a junction that is cased and has pressure isolation and reentry capabilities.
