A method and a lateral entry guide tool for deploying a work string in a wellbore defining a window and a lateral wellbore extending from the window are described. The work string and the tool are run through the wellbore to a distance above the window. A locator subassembly is activated to detect the window. The tool is run through the wellbore in a downhole direction from the distance above the window past the window. After the locator subassembly indicates that the tool is past the window, a window entry depth is determined based a depth at which the window was detected. The work string is pulled back to position the tool at the window entry depth. A positioning subassembly is activated. The work string is run through the window while adjusting and calibrating the positioning subassembly as the work string pass through the window into the lateral wellbore.

A tool for building a wellbore includes a tool body with a flow passage extending axially therethrough, a piston chamber formed radially through the tool body that intersects the flow passage of the tool body, a piston disposed in the piston chamber, at least one actuation element that exerts a force between the piston and the piston chamber, and a sleeve disposed within the flow passage of the tool body that includes at least one cutout. When the sleeve is in a first position within the tool body, the cutout is axially offset from the piston, and when the sleeve is in a second position, the cutout is axially aligned with the piston.

A method to produce in-situ steam comprising the steps of producing a laser beam in a steam generator segment positioned in a wellbore in a formation; introducing the laser beam to an activated carbon container, where the activated carbon container comprises activated carbon; increasing a temperature of the activated carbon with the laser beam to produce a hot activated carbon; introducing water to the activated carbon container through a water supply line; producing steam in the activated carbon container when the water contacts the hot activated carbon; increasing pressure in the activated carbon container as steam is produced until a pressure set point of an inter-container valve is reached; releasing steam through the inter-container valve to a steam container; increasing a pressure in the steam container until a release set point of one or more release valves is reached; and releasing steam through the release valve to the formation.

The disclosure presents apparatuses and systems to reduce drag and friction forces on a drill string located downhole a borehole. The drill string can have two or more movement isolators to allow a movement sensitive tool to be movement isolated from other portions of the drill string that have powered movement. The other drill string portions can be powered by a surface equipment or by a downhole movement motor attached to the drill string, such as a rotational mud motor, an agitator, a jar motor, or a rotary steerable. Portions of the drill string located further downhole than the movement sensitive tool can utilize a movement motor attached to the drill string to provide movement to reduce drag and friction force where the movement isolators can reduce the movement force experienced by the movement sensitive tool.

A dual clutch travel joint system includes an inner-mandrel and an outer-mandrel. The inner-mandrel includes a first connector on a downhole portion of the inner-mandrel and a second connector on an uphole portion of the inner-mandrel. The outer-mandrel includes a third connector that is positionable to mate with the first connector to apply torque to the inner-mandrel while the inner-mandrel is in a tension arrangement with the outer-mandrel within a wellbore. Additionally, the outer-mandrel includes a fourth connector positionable to mate with the second connector to apply torque to the inner-mandrel while the inner-mandrel is in a compression arrangement with the outer-mandrel within the wellbore.

An improved swivel with increased sealing capability at fluid pressures up to 20 ksi and at fluid temperatures as high as 250° F. and as low as 35° F. The swivel may be relatively compact, being less than 8 feet in overall length and can operate unpressurized with axial loads of at high as 1,400,000 lbs. The swivel may comprise a swivel mandrel rotationally coupled with a swivel housing. Rotational bearings units can be securely held using cartridge carriers. A pressure seal may be formed between the swivel mandrel and swivel housing via a redundant seal stack.
