Modular Whipstock Sidetracking System Saves 47 h on Deepwater GOM Well

Sidetracking operation mills clean, usable window and drills through 63 ft of salt in one trip

An operator drilling in the Gulf of Mexico (GOM) needed to produce a clean, usable window in one trip and drill a minimum 63 ft of rathole in the subsea salt formation. Using the TrackMaster Select system, the operator milled a clean, usable window in 7 h while building the angle in the rathole section from 3.16° to 4.3° to obtain accurate MWD high-side data with the directional assembly.
