DOWNHOLE TOOL ACTUATORS AND INDEXING MECHANISMS
A downhole tool control apparatus includes a control assembly, a stroking assembly, and a pocket sleeve positioned in an outer sub. The control assembly and stroking assembly are independently slidable axially within the outer sub. The control assembly and stroking assembly slide depending on the flow rate of fluid through the downhole tool actuator. The stroking assembly includes a spline barrel having a spline projection positioned within a spline pocket formed in the pocket sleeve. The pocket sleeve and control assembly include one or more ratchet teeth positioned in the pocket sleeve such that as the flow rate is changed between a high and a low flow rate, the spline projection engages the ratchet teeth until an actuated cycle is completed, allowing the downhole tool actuator to move to an actuation position.
Downhole tools, multi-lateral intervention systems and methods to deploy a tubular into a lateral borehole of a multi-lateral well
The disclosed embodiments include downhole tools, multi-lateral intervention systems and methods to deploy a tubular into a lateral borehole of a multi-lateral well. A downhole tool includes a mandrel having an angulated interior profile along a first side of the mandrel. The downhole tool also includes a nose coupled to a second side of the mandrel. The downhole tool further includes a link having an angulated exterior profile along a first side of the link that is rotatably coupled to the first side of the mandrel. The link is rotatable from a first position to a second position, and wherein the nose tilts at an angle relative to the link while the link is at the second position.
Drill pipe string conveyed retrievable plug system
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.
Deploying Material to Limit Losses of Drilling Fluid in a Wellbore
Bottom hole assemblies for deploying fabric can include: a body configured to be attached to a drill pipe; a control tube disposed inside the body at a position controlled by engagement of a cam with a continuous guide path; a set tube, the set tube and the body together defining a pressure chamber with the body defining an inlet port extending between the interior cavity and pressure chamber, the set tube movable between a rolling position and a reaming position; a reamer assembly with at least one first articulated arm with extending between first attachment point on the body and the set tube; and a roller assembly with: at least one second articulated arm extending between the set tube and a second attachment point on the body; and a roller positioned at a joint of each second articulated arm.
Multiple Cycle Deployable and Retractable Downhole Scraper or Brush
Systems and methods of the present disclosure relate to wellbore scraping operations. A method comprises running a scraper tool into a wellbore with blades retracted; dropping a ball into an expandable seat of the scraper tool to build pressure; pumping fluid into the scraper tool to deploy a mandrel to compress a spring to rotate a j-slot to a second position from a first position to extend the blades; building pressure until the ball is released from the expandable seat; and moving the mandrel to a third position on the j-slot to lock the extended blades in place.
Quarter-Turn Anchor Catcher Having Anti-Rotation Sleeve and Allowing for High Annular Flow
An anchor catcher tool can support tubing in casing. The tool is a slimline tool that can be set and unset with a partial (quarter) turn of a mandrel using a setting mechanism, such as a J-slot and pin arrangement. Uphole and downhole cages of the tool carry opposing slips. When set, the slips engage opposing cone faces to wedge against the casing and prevent movement of the tool. Excluded gas can flow up the annulus to the surface through aligned longitudinal flow paths on the exterior of the tool's components. To do this, a sleeve floating on the mandrel has the cone faces thereon and is longitudinally engaged with cages, which float on the mandrel and carry the slips. The sleeve keeps longitudinal channels on the cages and longitudinal divisions of the cone faces aligned with one another to produce the flow paths for annular flow.
FISH RETRIEVAL FROM WELLBORE
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.
ROTATING STINGER VALVE FOR J-SLOT CONNECTOR
A petroleum well toolstring valve includes a drill pipe string conveyed J-slot running tool for a top stinger on a retrievable bridge plug. The J-slot running tool includes a J-slot sleeve with J-slots for disconnectably receiving the stinger. The top stinger includes a cylindrical stinger portion with J-slot connecting lugs. An internal plug is arranged between a central connector and stinger bores. A cylindrical neck on the stinger portion spans the internal plug in the axial direction. The cylindrical neck, when covered by the J-slot sleeve, forms an annular flow space connecting upper and lower radial ports and thus central bores. The stinger portion has a rotatable sleeve valve body arranged on a stinger valve stem portion. The sleeve valve body has a sleeve valve port arranged for being aligned with the lower stinger port when rotated into an open position. The rotatable sleeve valve body is connected to the lugs for being rotated by the drill pipe string for opening or closing the valve.

Testable indexing plug
A testable indexing plug includes a body having an outer surface, an inner surface defining a flow path, a first end, a second end, and an intermediate portion extending between the first end and the second end. A valve chamber extends from the first end into the intermediate portion. A valve member is arranged in the valve chamber. The valve member includes a first end portion, a second end portion including an opening, and an intermediate section including one or more ports fluidically connected with the opening. An indexing system shifts the valve member between a first position, wherein the one or more ports are arranged in the valve chamber and a second position, wherein the one or more ports are exposed outside of the valve chamber following a defined number of pressure applications to the valve member.
