    摘要: Wellbore tool assembly to open collapsed tubing includes a chisel head having a first end configured to be positioned within an end of a collapsed tubing portion of a tubular member. The chisel head has a second end opposite the first end. The second end has an outer diameter smaller than an outer diameter of an uncollapsed tubing portion of the tubular member. The chisel head is configured to expand a diameter of the collapsed tubing portion responsive to a movement of the chisel head toward the collapsed tubing portion. The assembly includes a packer attached to the chisel head. The packer is configured to expand responsive to fluidic pressure and to further expand the diameter of the collapsed tubing portion.

    摘要: A packer assembly includes a tubing string disposed in a wellbore and a packer releasably coupled to the tubing string. The packer includes a housing releasably coupled to the tubing string, a packer slip, a flexible sealing element, a piston coupled to the housing, a locking member, and a mandrel disposed inside the housing. The piston moves to activate the packer slip and the flexible sealing element to set the packer on a wall of the wellbore. The locking member engages the piston to constrain movement of the piston to keep the packer set on the wall of the wellbore. The mandrel connects to the tubing string when the tubing string is released from the housing. The locking member is collapsible to disengage the piston to unset the packer slip and the flexible sealing element responsive to shear force applied by the mandrel to the locking member.

    摘要: A well tool for cementing a portion of a well includes a cement retainer assembly and a capsule connected to the cement retainer assembly. The cement retainer assembly is configured to be disposed within a wellbore, and includes a ported sub and a cement retainer. The ported sub includes a port to flow cement out of the cement retainer assembly and into an annulus of the wellbore. The capsule includes a body defining an interior chamber of the capsule, where the interior chamber is configured to retain a fluid, and the capsule is configured to be disposed at a location within the wellbore and downhole of the cement retainer assembly.

    摘要: A hollow milling-bit defines a first interior flow passage. A junk catcher sub is connected to the hollow milling-bit and positioned between the hollow milling-bit and the uphole end. A junk recovery tube is connected to the junk catcher sub and positioned between the junk catcher sub and the uphole end. A reverse circulation diverter sub is connected to the junk recovery tube and positioned between the junk recovery tube and the uphole end. The reverse circulation diverter sub includes a ball seat configured to receive a ball. The first recirculation passage fluidically connects the interior flow passage to an outer surface of the tool. The second recirculation passage fluidically connects the interior flow passage to an outer surface of the tool. A catch basket that defines openings is connected to a downhole end of the reverse circulation diverter sub and positioned in the third interior flow passage in-line.

    摘要: A method of plugging a formation fracture includes drilling, with a drill string configured to flow drilling fluid, a wellbore, where, at a downhole location, the drilling fluid is lost through a formation fracture. The method also includes deploying, through the drill string, a plugging assembly to the downhole location of the wellbore. The plugging assembly includes a flexible fiber sheet releasably coupled to a pumpable dart such that when the plugging assembly reaches the downhole location, the flexible fiber sheet is released from the dart to flow, with the drilling fluid, to the formation fracture to at least partially overlay the formation fracture. The method also includes adding, to the drilling fluid, lost circulation material configured to accumulate on a portion of the flexible fiber sheet to at least partially fluidically plug the formation fracture.

    摘要: An assembly and a method for maintaining and inspecting a wellbore are described. The assembly includes a body. Multiple magnetic wheel sub-assemblies are adjustably coupled to the body. The magnetic wheel sub-assemblies position the body within the wellbore and reposition relative to the body in response to a wellbore narrowing or a wellbore widening. The assembly includes a tool connection coupled to the body. The tool connection couples a well tool to the body. The assembly includes a control sub-assembly to control the magnetic wheel sub-assemblies and operate the well tool within the wellbore. The assembly includes a power sub-assembly to supply power to the control sub-assembly and the well tool. The assembly includes a backup retrieval mechanism coupled to the body. The backup retrieval mechanism couples to a retrieval tool.

    摘要: A first interval inflow control device and a second interval inflow control device are positioned on a production tubing string proximate to a first subterranean interval and a second subterranean interval, respectively. The inflow control devices each include a central bore, a sand screen surrounding an inner tube, a plurality of ports connect the annular space between an inner surface of the sand screen and an outer surface of the inner tube, and a sliding sleeve configured to translate between an open position and closed position. A first shifting tool is configured to engage with and axially translate the sliding sleeve of the first interval inflow control device and a second shifting tool is configured to engage with and axially translate the sliding sleeve of the second interval inflow control device. The second shifting tool has an outer diameter less than the bore of the first interval inflow control device.
