Abstract: A sealing assembly is disclosed, the sealing assembly comprising a plurality of components including an upper sealing element and a lower sealing element, the sealing assembly configured to encircle a tubular string positioned within a casing of a wellbore. The sealing assembly is configured to be actuatable to extend sealing elements between the tubular string and an inner surface of the casing to form a fluid seal between the tubular element and the inner surface of the casing.

Abstract: An actuation assembly positionable within a wellbore may comprise a primary piston coupled to a first spring. The primary piston may be positionable in a first position in which it is coupled to a release latch for restraining the release latch from actuating a ball valve mechanism. The actuation assembly may also include a locking piston coupled to a second spring and a locking mechanism positioned between the primary piston and the locking piston. The locking mechanism may be moveable between a restrained position and an unrestrained position, wherein in the restrained position the locking mechanism prevents the primary piston from moving a predetermined amount in a first direction in response to an application of pressure from a surface of the wellbore that is greater than a predetermined amount of pressure.

Abstract: An actuation system for remotely transitioning a downhole wellbore tool between distinct operational configurations includes a sensor that can detect a downhole pressure in a tubular string extending into a wellbore and an electronic decoder that monitors the pressure the tubular string until a target pressure profile is detected. When the target pressure profile is detected, the decoder issues a command to an actuation mechanism, causing the downhole wellbore tool to transition between the distinct operational configurations. The target pressure profile may be transmitted from the surface location by operating a pump to produce specific downhole pressure levels for specific time intervals. The specific downhole pressures do not need to be applied directly to the downhole wellbore tool, and thus the each of a plurality of various downhole wellbore tools may be operated independently without interfering with one another.

Abstract: A system and method for opening and closing a barrier valve. The system may comprise a plurality of production tubing sections, a barrier valve, and an actuation module attached to the barrier valve. The method may comprise attaching an actuation module to one of one or more production tubing sections, disposing the actuation module, the barrier valve, and the one or more production tubing sections into an annulus, moving the mandrel with the first piston or the second piston, and moving a ball within the barrier valve to a closed position.

Abstract: A downhole tool having an indexing apparatus for actuating the downhole tool from the surface by applying a pre-determined number of hydraulic pressure signals to the downhole tool. The downhole having an outer tubing that has an outer surface and an inner surface, the inner surface defining an inner region of the outer tubing. The downhole tool includes a sliding sleeve positioned within the inner region of the outer tubing, the sliding sleeve being slideable relative to the outer tubing. The sliding sleeve including a first magnet and a second magnet that are positioned in an opposing orientation relative to one another for providing a reference point detectable via a magnetometer at a surface of a wellbore. An indexing position of the downhole tool being determined by comparing a location of the reference point on the sliding sleeve to a location of a fixed point on the outer tubing.
