    摘要： An example whipstock assembly includes a whipstock providing a ramped surface and a longitudinal groove defined in the ramped surface. A lead mill is coupled to the whipstock with a shear bolt and having a slot defined therein, and a torque key is movable between an extended position, where the torque key is partially positioned within both the slot and the longitudinal groove, and a retracted position, where the torque key retracts into the slot. When the torque key is in the extended position, the torque key prevents the lead mill from rotating with respect to the whipstock.

    摘要： An apparatus comprises a housing (22) having an interior (30) and a first housing end. The apparatus includes a shaft (104) rotatably connected with the housing (22). The shaft (104) comprises a shaft extension (50) that extends from the interior of the housing (30) at the first housing end, and wherein the shaft extension (50) defines a first bearing surface. The apparatus includes a first thrust bearing (62) located axially between the first housing end and the first bearing shaft surface, for transferring a first axial load between the shaft (104) and the housing (22).

    摘要： A technique facilitates efficient data transfer during a drilling operation. The drilling operation involves deploying a drill string downhole and rotating a drill bit to cut a borehole into a subterranean formation. While the drill bit is on bottom, real-time sensor data is transmitted to a surface location or other suitable location via a data transmission system. The transmission of current or real-time sensor data is stopped when the drill bit is moved off bottom. While the drill bit is off bottom, previously recorded data is sent uphole.
