摘要： A whipstock assembly including a main body defining an axial direction extending through the main body, a circumferential direction, and a radial direction transverse to the axial direction, and a ramp body pivotally coupled to the main body, the ramp body defining a ramp surface that is oriented transverse to the radial direction, and where the ramp body is movable between a retracted position and an extended position, where the ramp surface is further from the main body in the axial direction in the extended position as compared to the retracted position and the ramp body is rotatable with respect to the main body about the circumferential direction.

摘要： A wellbore assembly includes a cable and a wellbore tool. The wellbore tool is coupled to the downhole end of the cable. The wellbore tool includes a housing, one or more sensors, a packer, and a controller. The one or more sensors are coupled to the housing or to the cable or both. The sensors detect one or more parameters of the wellbore tool or the cable or both. The controller is coupled to the housing. The controller is electrically coupled to one or more sensors and is operationally coupled to the packer. The controller determines, with the wellbore tool parted from the cable and based on information received from the one or more sensors, an indication of the wellbore tool in free fall. The controller activates, based on the determination, the packer to expand the packer and set the wellbore tool on a wall of the wellbore.

摘要： A smart jarring system for freeing stuck equipment downhole is disclosed. The smart jarring system comprises a set of jars, at least one laser source and at least one laser receiver that corresponds to the at least one laser source. The laser receiver intercepts a laser beam that is emitted from the laser source. This interception helps determine when the set of jars fired and in which direction the set of jars fired. The smart jarring system further comprises one or more sensors selected from the group consisting of vibration sensors, temperature sensors, and torque/tensile sensors. These sensors are configured to diagnose downhole conditions and help free the stuck equipment downhole.

摘要： Techniques for removing a tubular from a wellbore include running a downhole tool on a downhole conveyance into a wellbore formed from a terranean surface into a subterranean formation; activating a piston sub-assembly to repeatedly move pistons to contact a portion of a casing installed in the wellbore to at least de-bond a cement layer installed between the portion of the casing and the subterranean formation from the portion of the casing; activating a cutting sub-assembly to move a cutting blade to cut through the portion of the casing adjacent the de-bonded portion of the cement layer; activating a hanger sub-assembly to move a set of slips into contacting engagement with the cut portion of the casing; and running the downhole tool on the downhole conveyance out of the wellbore with the cut portion of the casing engaged with the set of slips.
