Types & Variants
Permanent Whipstock
Run in the hole on the bottom of the drill string attached with a shear pin, with roughly 30 feet of tail pipe run below as an anchor. The assembly is landed near bottom, oriented by conventional methods, then landed on bottom and cemented in place.
Retrievable Whipstock
Run in the hole nearly to bottom; orientation is checked with a single-shot and the whipstock face is oriented as required before the tool is set on bottom. Depending on type, a ball may be dropped down the drill string to divert flow from the bottom of the whipstock to the drill bit.
