    摘要: An electric motor-actuated tractor (e-Tractor) apparatus and method for use in downhole operations. The apparatus includes a power subassembly, a tractor subassembly and one or more gripper subassemblies and can be: run in a single or multiple e-Tractor configuration; run in either intermittent-motion tractoring mode or continuous-motion tractoring mode with the ability to switch between the two modes; used to generate both distal and proximal longitudinal forces to move the run-in string into or out of the wellbore; repeatedly activated and deactivated without run-in string manipulation or hydraulic pressure; and combined with tensiometer and other sensor package options to provide real-time data to the surface to optimize tractoring operations. The apparatus and method are well-suited for application in an c-coil conveyed workover or completion system, and for use in extended reach laterals in horizontal wells.

    摘要: A tool includes an internal assembly configured to be positioned at least partially within a body. The tool also includes a collet configured to be positioned at least partially within the body and axially-adjacent to the internal assembly. The collet includes a plurality of fingers that are circumferentially-offset from one another. At least one of the fingers includes a protrusion that extends adially-outward and is configured to be positioned at least partially within a recess formed in an inner surface of the body to secure the collet in place with respect to the body. The tool also includes a collet pin configured to be positioned at least partially within the body, axially-adjacent to the internal assembly, and at least partially within the collet. The collet pin is configured to contact the internal assembly to secure the internal assembly in place within the body.

    摘要: A logging system for a tubular includes: a rail system comprising a plurality of rails and mounted to a surface of the tubular; a logging tool carrier connected to the rail system; and a logging tool disposed on the logging tool carrier. The logging tool is deployed on the logging tool carrier connected to the rail system along the tubular to a targeted position along the tubular and then retrieved from the wellbore. During deployment of the logging tool, the logging tool acquires a plurality of logging data.

    摘要: Downhole tractor control systems and methods to maintain a load of a downhole tractor are disclosed. A method to maintain a load of a downhole tractor includes identifying a reduction of power of a first set of motors of a plurality of motors of the downhole tractor, determining whether the reduction of power of the first set of motors is below a first threshold, and increasing, in response to the determination, a first power limit of a second set of motors of the plurality of motors to a maximum acceptable power limit of the second set of motors while maintaining the load of the downhole tractor.

    摘要: A drill pipe string conveyed retrievable plug system has a central through bore. The plug system includes a drill pipe string; a control section; a running tool with a connector at a lower end of a drill pipe string with the control section, and a top connector on a mechanical plug section with a bridge plug. The mechanical plug section includes a mandrel with the through bore, a ball valve arranged for closing the through bore, and a packer sleeve on the mandrel with slips and a packer element. The control section includes an electric supply, an electric control unit, and sensors connected to the electric control unit. The mechanical plug section includes a motor controlled by the electrical control unit. The motor is arranged to turn a selector ring to a selected first rotational position so as for allowing a piston sleeve to slide to an axial first stop position in order for opening to fluid channels through the mandrel from the through bore to the packer sleeve. The pressure in the through bore can be set to the pressure of the packer sleeve in a surrounding casing.

    摘要: An apparatus includes a housing, engagement slips, a tubular, a taper tap, a pin, and a slip activation member. The housing includes a profile that defines a path including a first end and a second end. The engagement slips are attached to the housing. The tubular passes through an opening of the housing. The taper tap is rotatable and connected to the housing. The pin is connected to the tubular and received by the profile of the housing. The tubular is translatable with respect to the housing based on the pin translating along the path defined by the profile. The slip activation member is connected to the tubular. The slip activation member is configured to move each of the engagement slips radially outward with respect to the housing when the pin translates to the second end of the path.
