A valve assembly for an inflatable packer includes an opening valve configured to actuate into an open position in response to a first pressure within a tubular string, so as to permit fluid flow from the tubular string, through the valve assembly, and into an inflatable packer element. The valve assembly also includes a closing valve configured to actuate into a closed position so as to prevent fluid flow from the tubular string, through the valve assembly, and into the inflatable packer element in response to a second pressure within the inflatable packer element. The valve assembly also includes a contingency valve configured to actuate into a closed position so as to prevent fluid flow from the tubular string, through the valve assembly, and into the inflatable packer element in response to a third pressure in the tubular string.

A cement plug system includes a first plug configured to catch a first obstruction member and actuatable from a locked configuration to an unlocked configuration in response to an axial force transmitted to the first plug by the first obstruction member, and a second plug adjacent to the first plug and configured to catch a second obstruction member, the second plug having a pass-through configuration in which the first obstruction member passes through the second plug, and a catching configuration in which the second plug catches the second obstruction member, the first obstruction member is at least as large as the second obstruction member. The second plug actuates from the pass-through configuration to the catching configuration in response to the first plug shifting from the locked configuration to the unlocked configuration, and the first plug in the unlocked configuration separates from the second plug.

A downhole tool and method, of which the downhole tool includes a housing defining a charge chamber and a hydraulic chamber, the hydraulic chamber containing a hydraulic fluid, and a piston disposed in the hydraulic chamber. The piston prevents the hydraulic fluid from communicating with the charge chamber, and is in communication with the hydraulic fluid and the charge chamber. The tool also includes one or more charges disposed in the charge chamber. The one or more charges are configured to ignite and thereby expand a gas in the charge chamber. The tool further includes a fluid-metering device coupled to the housing. The fluid-metering device is configured to control a rate at which the hydraulic fluid is pressed out of the hydraulic chamber.

A stop collar includes an annular body and a gripping member. The body includes an outer surface and an inner surface. The body defines a window extending from the outer surface to the inner surface. A portion of the inner surface has a diameter that decreases proceeding toward an axial end of the body. The gripping member is positioned at least partially within the body and in contact with the inner surface. The gripping member is at least partially aligned with the window when the stop collar is in a first state. The gripping member moves toward the axial end of the body when the stop collar actuates into a second state. A diameter of the gripping member decreases as the gripping member moves toward the axial end of the body.

A plug assembly, an anchor tool for a plug, and methods for deploying a plug in a wellbore, of which the anchor tool includes a body, engaging members coupled with the body and configured to expand outward from the body, and a sliding sleeve positioned at least partially around the body. When the sliding sleeve is in a first position, the sliding sleeve covers the engaging members and restrains the engaging members from expanding, and when the sliding sleeve is in a second position, the sliding sleeve uncovers the engaging members and permits the engaging members to expand. The anchor tool also includes a friction-inducing member positioned around the body, and a shearable member coupled with the friction-inducing member and the body. The shearable member restrains the friction-inducing member, causing the friction-inducing member to maintain the sliding sleeve in the first position, until the shearable member is sheared.
