  • Patent number: 12006800
    Abstract: A gravel pack assembly for a borehole has first and second joints and a foil. The basepipes of the joints connect end-to-end, and both of the basepipes have filters for filtering fluid passage from a borehole into bores of the basepipes. Transport tubes are disposed along the first and second joint, and a jumper tube expands across the connected ends of the basepipes and connects the transport tubes together. The foil encloses an area across the connected ends. The foil has an external surface defining an annulus thereabout with the borehole. The foil has end rings abutting the filters of the joints. At least a section of the foil leaks fluid from the borehole to the area enclosed by the foil, and at least a filter portion of the assembly filters the leaked fluid from the area to at least one of the first and second bores.

  • Patent number: 12000219
    Abstract: A method of making-up tubular string components can include inputting to an image processor image data output from at least one camera, the image processor in response detecting positions of a tubular and a mark on another tubular, threading the tubulars with each other while inputting position data from the image processor to a controller, and the controller terminating the threading in response to the position of the mark relative to the position of the first tubular being within a predetermined range. Another method of making-up tubular string components can include, in response to inputting image data to an image processor, the image processor detecting longitudinal positions of two tubulars, threading the tubulars with each other, and a controller terminating the threading in response to the longitudinal position of one tubular relative to the longitudinal position of the other tubular being within a predetermined range.

  • Patent number: 11993999
    Abstract: A well barrier can include an annular seal element, an anti-extrusion backup having radially inward and radially outward portions, and a biasing device that exerts a biasing force against the radially outward portion of the anti-extrusion backup. A method of operating a well barrier can include setting the well barrier by decreasing a longitudinal distance between abutments of the well barrier, thereby compressing a seal element between the abutments, and unsetting the well barrier by increasing the longitudinal distance between the abutments and radially inwardly retracting an anti-extrusion backup positioned longitudinally between the seal element and one of the abutments. Another well barrier can include an annular seal element, an anti-extrusion backup, an abutment displaceable relative to the seal element to compress the seal element, a sleeve reciprocable relative to the abutment, and a biasing device that biases the sleeve toward the anti-extrusion backup.

  • Publication number: 20240167353
    Abstract: A downhole tool, such as a bridge plug, has a carrier disposed on the tool between the opposing cones. Slips are disposed adjacent to the tool between the carrier and the cones. One arrangement has a proximal end of each slip connected by a linkage configured to articulate the proximal end relative to the carrier, while a distal end of each slip is configured to engage the cone opposed thereto. The linkage can be a linkage hingedly connected between the slip's proximal end and the carrier. Alternatively, the linkage can be a leaf spring flexibly connected between the slip's proximal end and the carrier. Another arrangement has linkages hingedly connected to the carrier and hingedly connected toward opposing ends of each slip. The linkages articulate the slip relative to the carrier while the ends of the slip engage the opposing cones.

  • Patent number: 11988064
    Abstract: An apparatus can include a choke with a flow restrictor having at least two positions, a flow coefficient Cv of the choke with the flow restrictor in one position being less than with the flow restrictor in the other position, and an operational device that displaces the flow restrictor at a variable actuation rate, the actuation rate with the flow restrictor in one position being less than with the flow restrictor in the other position. A method can include displacing a flow restrictor, thereby decreasing a flow coefficient Cv of a choke, and decreasing a rate of change of the flow coefficient Cv in response to decreasing the flow coefficient Cv. A drilling system can include a choke with a flow restrictor, and a continuously variable transmission which causes an actuation rate to vary based on a position of the flow restrictor.

  • Patent number: 11867019
    Abstract: When cementing tubing in a borehole, a wet shoe track is created, and pressure testing of the tubing is performed. To do this, a wiper plug seats in a seat of an insert disposed in a first position in a flow bore of a tool. The insert is released and moved toward a second position in the flow bore in response to the first pressure applied against the seated wiper plug. A collar disposed on the wiper plug seats on a second seat disposed uphole of the first seat. The tubing is pressure tested by applying pressure down the tubing against the wiper plug with the collar seated in the second seat. Fluid communication is then established through the flow bore downhole of the wiper plug, the first seat, and the second seat by removing the collar from the wiper plug. This can create the wet shoe track.

  • Patent number: 11834917
    Abstract: A sleeve can be used as a stop collar on tubing. A fusible element disposed about the inside or outside surface of the collar can be accessed by electrodes via the at least one access point in the collar. An insulator insulates the fusible element from the collar, while the electrodes apply electric current to the fusible element. A fusible material of the fusible element is heated to melting in response to the applied electric current and affixes the collar to the tubing with a metallurgical bond formed from the melting and re-solidifying of the fusible material inside a space between the first circumferential surface of the collar and the opposing circumferential surface of the tubing. The fusible material can be heated to melting directly with the electric current, or an ignitable material activated with the electric current can melt the fusible material.

  • Patent number: 11815380
    Abstract: Near-Infrared (NIR) filter photometry is used to calculate component concentrations in multiphase flows. The disclosed methodology adapts the Beer-Lambert law for nonhomogeneous immiscible mixtures (such as oil and water) by modeling the fluid layer as a nonhomogeneous distribution of its components and deriving a mathematical relationship between measured absorbances, component path lengths, and non-homogeneity factors. The methodology is integrated into a multi-channel filter photometer to measure phase concentrations in oil-and-gas pipelines. The system is proven more accurate than current state of the art based on data from simulations, multiphase flow laboratories and field trials.
