The Baker Hughes WindowMaster G2™ whipstock system requires only one trip with drillpipe to complete a window and drill a pilot hole. It features a full-drift outside diameter window mill that requires less rathole to be drilled, which saves valuable rig time. This state-of-the art system saves substantial rig time by eliminating at least two round trips with drillpipe that are required by conventional window-cutting systems.

The WindowMaster G2 system can be run in hole, oriented to the new hole direction, anchored in place, and completely mill a window, all in one trip. Orientation can be performed with measurement-while-drilling, universal bottomhole orientation, or gyro into packer profile. In addition, the milling bottomhole assembly eliminates the risks of mill connection and body failure during milling. The system is retrievable when run with the TorqueMaster™ bottom trip anchor or TorqueMaster packer in conjunction with a retrievable anchor. Two retrieving-tool options ensure retrievability in a wide variety of hole conditions. The WindowMaster G2 window mill incorporates Baker Hughes METAL MUNCHER™ cutting structures. METAL MUNCHER technology enables the operator to mill the window quickly and efficiently without sacrificing window quality, and apply minimum weight and torque to the workstring. The resulting cuttings are small and easily circulated out of hole. The WindowMaster G2 whipstock system is compatible with the Baker Hughes PathMAKER™ formation mill, which provides exceptional milling and drilling performance in hard formations. When used together, the WindowMaster G2 whipstock system and PathMAKER formation mill can provide several hundred feet of rathole if required to fit large rotary steerable drilling assemblies out of the casing.
