A specialized valve allows a whipstock to be oriented quickly with a measurement-while-drilling (MWD) tool. The apparatus permits the proper "set" of a mechanical packer without fear of shearing the releasable attachment device currently used in the industry and permits an operator to "bottom hole wash. This was made possible thanks to the recent partnership between SPT and its local distributor company, Goryzonty . The neutralizer causes the. The next major advance was in the 1970s, when downhole drilling motors (aka mud motors, driven by the hydraulic power of drilling mud circulated. Sidetracking with hydraulic anchor whipstock system, that can be used in both open hole and cased wellbores. Drilling in this deep water field was conducted from a drill ship. (2) Oriented perforating for production engineering. • The unique lug technology protects the whipstockThe rock may be of sufficient strength that the drill bit will cut through the steel of the whipstock rather than the surrounding rock. Thread 18 is also intended to schematically represent the possibility for attachment of various orientation tools of the type known in the art. The utility model relates to the field of drilling, maintenance and workover of oil and gas wells, namely, it is used for re-entry of a technological tool into a sidetrack of a multilateral well during its operation or workover. A method and apparatus is disclosed which allows running in a whipstock packer in combination with a setting assembly, which also includes instrumentation to sense the depth, as well as orientation of the anchor orientation groove on the packer. The Whipstock needs to be positioned so that the window is milled across the joint of the casing and a coupling or connection. Referring now to FIGS. This tool doesn’t need the collar azimuth, making it an absolute measurement without operator dependence. Abstract. The geothermal anchor packer is designed to fix the whipstock orientation and to pressure isolate the lower casing from the upper casing. Adjustable-gauge stabilizers, known as “2D rotary systems,” have become quite popular to run with the rotary and PDM assemblies to control inclination. A whipstock inside the existing casing was essential to start in the desired location. The present invention, in one embodiment, discloses a whipstock system having an orientation device; a flexion member releasably secured to the orientation device; co-acting lower and upper body members, the lower body member interconnected with the flexion member; a connecting bar which connects the upper and lower body members. Alternatively, an MWD tool also could provide the orientation along with the other directional measurements during drilling operation. Publication Publication Date Title. The whipstock then has a very sharp slope at the bottom of the whipstock which would act to shove the mill to the side. Then all tools above the whipstock 50 are withdrawn from the well as the coil tubing 17 is wound back onto the reel 18.
