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.

A pressurizable assembly which comprises first and second assemblies. The first assembly has a plurality of cam grooves while the second assembly is size and shaped to intimately receive and mate with the first assembly. The second assembly has a connection member a plurality of radially mounted locking pin mechanisms for interacting with one of the plurality of spaced apart cam grooves. Axial movement of the second assembly, toward and away from the first assembly, causes the plurality of locking pin mechanisms to follow along the cam grooves to an intermediate locking position which locks the second assembly with the first assembly, while a subsequent axial movement of the second assembly, toward and away from the first assembly, causes the plurality of locking pin mechanisms to follow along the plurality of cam grooves and disengage the second assembly from the first assembly.

Provided is a keyed running tool for use with a slotted orientation apparatus. The keyed running tool, in one aspect, includes a housing, and two or more keys extending from the housing, the two or more keys movable between a radially retracted state and a radially extended state, wherein adjacent ones of the two or more keys are laterally offset from each other and radially offset from each other by Y degrees, wherein Y is 180 degrees or less.

Provided is a slotted orientation apparatus for use with a keyed running tool. The slotted orientation apparatus, in one aspect includes a tubular having a wall thickness (t), and a slot extending at least partially through the tubular, the slot having an angled portion coupled to an axial portion, wherein the slot radially extends around the tubular X degrees, wherein X is 180 degrees or less.

An apparatus for fitting to a wellbore, the apparatus including: a self-propelled downhole tool for deployment within the wellbore, and configured to propel itself along at least part of a length of the wellbore; and a lubricator for fitting to a wellhead of the wellbore via a valve system providing communication between the lubricator and the wellbore, and for housing the self-propelled downhole tool when in a stowed position, wherein the lubricator includes an input port for receiving data from a remote unit, the input port being in electrical communication with the self-propelled downhole tool when in the stowed position, and wherein the received data includes instructions for operating the self-propelled downhole tool, and associated self-propelled downhole tool, lubricator and method.

A rotary lock system includes a gear configured to be driven to rotate via an engine. The rotary lock system includes a rotatable starter component configured to engage the gear via an interface. The interface includes a circumferential gap to enable the gear to rotate through an angle before contacting and driving the rotatable starter component.

A downhole tool actuation system including: a tubing having a longitudinal axis and a main flowbore supportive of tubing pressure; an indexing mechanism in fluidic communication with the main flowbore, the indexing mechanism configured to count N number of tubing pressure cycles; a port isolation device movable between a blocking condition and an actuation condition, the port isolation device in the blocking condition for N−1 cycles of the indexing mechanism, and movable to the actuation condition at the Nth cycle of the indexing mechanism; and, a chamber sealed from the main flowbore in the blocking condition of the port isolation device, the chamber exposed to the tubing pressure in the actuation condition of the port isolation device. The downhole tool actuation system is configured to actuate a downhole tool upon exposure of the chamber to tubing pressure.

The disclosed device provides a high-accuracy plunger arrival detection system comprising a low-power magnetometer with high sensitivity and which is capable of sampling low or high intensity magnetic fields. The device processes gathered data from sensors, stores at least some processed data in memory, executes a trending algorithm which compares the magnetic field of the plunger to the ambient magnetic field or a predetermined set of initialization values, and generates an output which is relayed to a well controller. An output signal may be via hard wire, RF, wireless or other known means. In addition, the implementation of two sensing devices mounted in series and in spaced relation to each other, can provide for an actual plunger average velocity. An actual plunger average velocity, as opposed to approximate average velocity, can be used to better optimize well control and improve safety of the overall well production system.
