A string includes a pipe that is connected to an expansion mechanism and a retrieval tool that is connected to the pipe above the expansion mechanism. The retrieval tool includes a carrier that can selectively latch on an expandable liner and one or more actuators. The retrieval tool can ensure latching of the carrier while the expandable liner is above the Blow-out Preventer. The retrieval tool can prevent accidental latching of the carrier on the expandable liner during the expansion of the liner. By manipulating the pipe, the retrieval tool can force the carrier's release from the expandable liner.

A resource exploration and recovery system includes a first system and a second system extending into a wellbore. The second system includes a completion having a casing defining a wellbore internal diameter. A chemical injection tubing extends from the first system into the completion. The chemical injection tubing includes a terminal end portion. A chemical introduction system is arranged at the first system and is fluidically connected to the chemical injection tubing. The chemical introduction system is operable to deliver a chemical into the chemical injection tubing. A chemical injector assembly is mounted to the terminal end portion. The chemical injection system includes an anchor and a chemical injector valve.

A method includes positioning a casing into a wellbore. Cement is pumped through the casing to cement the casing in the wellbore. A casing hanger is positioned within a casing head spool that is part of a surface wellhead assembly at an uphole end of the wellbore. The casing hanger is attached to an uphole end of the casing. A production tubing string including a plurality of production tubing segments is positioned within the casing within the wellbore. An uphole end of the production tubing string is attached to a lower end of a rotating inner mandrel of a production tubing hanger. The production tubing hanger is configured be positioned within a tubing head spool positioned above the casing head spool within the surface wellhead assembly. The rotating inner mandrel is configured to rotate within a non-rotating housing of the production tubing hanger. The production tubing string is rotated by rotating a landing joint including a production tubing segment attached to an upper end of the rotating inner mandrel. While rotating the production tubing string, cement is pumped through the production tubing string to at least partially cement the production tubing string within the wellbore.

A gravel pack system includes a liner assembly and a deployment assembly. The liner assembly includes a sand control screen. The deployment assembly facilitates rotation of the liner assembly and circulation through the liner assembly while running the liner assembly into a wellbore using a work string. The deployment assembly includes a crossover tool that is operated to facilitate gravel packing without manipulation of the work string. The deployment assembly also includes a setting tool for setting a packer and/or a sand barrier at the top of the liner assembly.

A wellbore isolation assembly includes an outer component and an inner component. The outer component is disposed at a first location in a wellbore. The inner component is disposed at a second location in the wellbore. The inner component is moved from the second location into engagement with the outer component at the first location to form a barrier within the wellbore. When deployed in the wellbore, the barrier inhibits passage of fluids. The wellbore isolation assembly is then retrieved from the wellbore.

A wellhead system includes a wellhead including a position sensor disposed in an inner surface of the wellhead, and a wellhead component to be installed in the wellhead, the wellhead component including a position indicator disposed in an outer surface of the wellhead component, wherein the position sensor is configured to transmit a position signal in response to the wellhead component entering into a predetermined aligned position in the wellhead.

A tool is provided for expanding the casing at one or more locations for arresting surface casing vent flow in an abandoned well. A setting tool is run into the bore having an expansion element supported thereon. The setting tool imparts a large axial force to radially expand the expansion element for plastically deforming the casing. A single use, pleated ring crushable expansion element can be actuated and left downhole. The pleated ring tool can be pre-charged with a highly viscous fluid, semi solid for transport, but plastic under load. A multi-use expansion element can be actuated, released, moved and actuated again at successive locations.
