Our whipstock systems increase project effectiveness.

The hydraulic-set PathMaster™ and WindowMaster™ G2 whipstock systems allow the use of hydraulically-activated anchor and packer systems with proven, one-trip whipstock systems. These systems offer a secure hydraulic communication link to below the whipstock, which enables whipstock anchoring devices to be hydraulically activated and set and the casing window milled in one trip.

Window milling performance is identical to the nonhydraulic versions of the PathMaster and WindowMaster G2 whipstock systems. When run with retrievable anchors, whipstock retrieval is also the same. Full-gauge mills provide a drift window and rathole. Short whipstock ramp provides quick kickoff, and shorter overall BHA allows system to pass through high doglegs.

Only one drillpipe trip is required to mill the casing exit and drill the pilot hole. Systems are retrievable for multiple-zone applications, and they allow MWD, UBHO, or gyro into packer for orientation. Patented METAL MUNCHER™ cutting technology produces faster, cleaner cuts.

The PathMaster whipstock system combines the one-trip and retrievable features of the field-proven WindowMaster whipstock with a shorter whipstock ramp and full-gauge mills. This system provides a quicker kickoff with a higher build rate in short-radius drilling applications. Shorter whipstock length and a compact milling assembly form a significantly shorter window-exit BHA capable of passing through higher doglegs in the wellbore.

The WindowMaster G2™ whipstock system combines a one-trip capability with a full-drift OD window mill. The full-drift window mill requires less rathole to be drilled, which saves rig time. The WindowMaster G2 system can be run in hole oriented to the new hole direction, anchored in place and a window completely milled, all in one trip. This state-of-the art system saves substantial rig time by eliminating at least two round trips with drillpipe, which are required by conventional window-cutting systems.

In addition, the milling BHA eliminates the risks of mill connection and body failure during milling. Orientation can be performed with MWD, UBHO or gyro into the packer profile. The system uses METAL MUNCHER cutting technology and TorqueMaster™ packer technology for high-pressure/high-temperature applications.

The WindowMaster whipstock system is the first true one-trip window-cutting system with an extended whipstock face for reduced dogleg severity. The system can be run in hole, oriented to the new hole direction, anchored in place, and a window completely milled, all in one trip. This system saves substantial rig time by eliminating at least two round trips with drillpipe, which are required by conventional window-cutting systems.
