摘要： A method for securing a downhole assembly to a casing string disposed within a wellbore includes moving, in a first direction, at least a portion of the downhole assembly within a passageway of a landing nipple that forms a portion of the casing string; exchanging a wireless signal between a first communication device that is coupled to the downhole assembly and a second communication device that forms a portion of the nipple; and preventing further movement of the downhole assembly, relative to the nipple, in the first direction in response to the exchange of the wireless signal and when the first communication device is spaced from the second communication device in the first direction.

摘要： A buoyancy assist tool has an outer case and a sleeve disposed in the outer case. The sleeve is movable from first to second positions in the outer case. A permeable membrane is attached to the movable sleeve at a lower end thereof. A rupture disk is mounted in the outer case. Fluid flow through the permeable membrane detaches the sleeve from the outer case and moves the sleeve from the first to the second position. In the second position, the sleeve creates an open bore for the passage of downhole tools therethrough.

摘要： An array of sensors provided on the outside of a tubular string for measuring a property within the tubular string. The array of sensors may include a plurality of connected sensors, wherein at least one of the plurality of connected sensors is at least partially encompassed in a shroud. A snorkel line may extend from the shroud, the snorkel line capable of coupling with a sensor port in a tubular of the tubular string. The snorkel line may establish fluid communication between one of the sensors at least partially encompassed in the shroud and a corresponding sensor port of a tubular in the tubular string.

摘要： A wellbore isolation device is provided which includes a tubular body having an external surface and an inner bore formed longitudinally through the tubular body. The tubular body has an expanding section transitionable from an initial configuration to an expanded configuration. One or more fins project radially from the external surface of the expanding section. The fins are anchorable into surrounding surfaces when the expanding section transitions to the expanded configuration. A plugging element is positioned, after the expanding section is in the expanded configuration, to restrict fluid communication through the inner bore.

摘要： A system and method for performing subterranean operations. The system may comprise an expandable liner hanger positioned within a casing string, wherein the expandable liner hanger comprises a spiked portion having one or more anchoring ridges, each of the one or more anchoring ridges extending in a circular ring along an outer perimeter of the expandable liner hanger, and one or more weep holes are positioned in a space between adjacent ones of the one or more anchoring ridges. The method for coupling a liner to a casing string of a cased wellbore in a subterranean formation may comprise coupling an expandable liner hanger to the liner, inserting the liner and the expandable liner hanger downhole through the casing string, and expanding the plurality of anchoring ridges.

摘要： An apparatus that is usable with a well includes a tubular assembly and an expansion tool. The tubular assembly has a radially contracted state and includes a restriction. The restriction is adapted to catch an object that is deployed into the well to form a fluid barrier when caught by the restriction. The expansion tool is deployed downhole with the tubular assembly inside a tubing string. The expansion tool is adapted to deform the tubular assembly to anchor the tubular assembly to the tubing string.

摘要： Drilling tools are frequently subject to rotation with respect to the central drilling axis caused by torque. A mechanical linkage can be configured to apply force that is proportional to the weight-on-bit on the borehole surface while transmitting axial loads used to generate weight-on-bit. The device can be used to manage drill string twist that could lead to drilling dysfunctions.

摘要： A downhole tool for applying a force to a component in a borehole penetrating a subsurface formation includes an acoustic transducer configured to receive an acoustic signal. The tool also includes a spring having a spring force, a spring force retention device defining a perimeter having a gap and in mechanical communication with the component where the spring force retention device being configured to retain the spring force, and a gap member configured to be disposed in the gap. The tool further includes a force generator coupled to the gap member and in operable communication with the acoustic receiver and configured to operate in response to receiving the acoustic signal to withdraw the gap member from the gap to cause the spring force retention device to release the spring force thereby applying the spring force to the component.

摘要： A method of performing an operation in a well having a conduit includes deploying a tube liner having a lay-flat state into a tubular structure positioned in the well. Fluid is injected into the tube liner to radially expand the tube liner to conform to a tubular wall surface of the tubular structure and thereby provide a protected portion of the conduit within the tubular structure.

摘要： The present disclosure relates generally to equipment utilized and operations performed in conjunction with a subterranean well and, more particularly, to an improved liner hanger system. A downhole expandable liner hanger positionable in a subterranean wellbore may comprise an expansion element. The expansion element may comprise a tubular body. The expansion element may comprise one or more annular seals bonded to the tubular body. The expansion element may comprise a first spike extending from the tubular body. The expansion element may comprise a second spike extending from the tubular body. The downhole expandable liner hanger may further comprise a first slip ring, wherein the first slip ring is disposed around the tubular body of the expansion element between the first spike and the second spike, wherein the first slip ring is configured to expand radially as the expansion element expands.
