Abstract: A liner hanger system enables installation of a liner hanger by means of a full bore casing to surface and provides pressure integrity between the casing's inner and outer sides. The liner hanger system comprises a liner hanger, along with an associated liner, coupled to a tieback casing string. The liner hanger and liner are deployed downhole connected to a tieback casing string. Once the liner has been lowered to the position of interest, first the liner hanger is anchored and cemented in position, and then, a packer is set to seal the lower annulus of the liner. The liner hanger system enables operations that used to require a plurality of trips, to be performed in a single trip. It does so without introducing any unwanted limitation to the inner diameter at any point between the wellhead and the end of the liner, and while also allowing for potential decoupling and removal of the tieback casing string from the liner hanger if desired.

Abstract: A multi-zone, one trip completion system for a wellbore is described. A plurality of isolation packers is installed in borehole to isolate a plurality of zones of the annulus between a tubing string and a wellbore. Each tubing string section is positioned in a zone and comprises a selectively openable stimulation port to provide stimulation fluid to its zone and a selectively openable production port to receive fluid from its zone. The system also comprises a circulation system with a plurality of circulation tubes and circulation tube valves, being configurable in a plurality of configurations to selectively connect, via a circulation flow path, the central bore or the borehole annulus of a wellbore at each of the plurality of sections, to an upper circulation flow path open to an annulus above an uppermost of the plurality of isolation packers.

Abstract: An apparatus for fluid treatment of a wellbore includes (a) a tubing string having (i) a wall defining an inner bore extending along a longitudinal axis, and (ii) a plurality of spaced apart ports in the wall; and (b) a plurality of axially spaced apart valves configured to permit fluid to flow therethrough. The valves are mounted along the tubing string. Each valve is (i) moveable in a downhole direction along the inner bore from a first position in which the one or more of the plurality of ports are closed, to a second position in which the one or more of the plurality of ports are open, and (ii) having a minimum inner diameter with respect to an innermost surface of the valve when the valve is in the first position. The minimum inner diameter of each valve is generally equal.

Abstract: A latch and perf assembly for completion of a wellbore comprises a setting tool with an explosive charge and a wireline connector, a run-in tool installed on the setting tool, a latch installed on the run-in tool and adapted to assume a retracted state during run-in of the assembly and an expanded state when the latch arrives at a predetermined depth in the wellbore and a seal inside the latch adapted to seal against hydraulic pressure applied from surface. The assembly is adapted to be run into the wellbore attached to a wireline, and at least a predetermined part of the seal is adapted to dissolve after fracking of the wellbore.

Abstract: A wellbore assembly including an actuation dart for actuating a target tool in tubing string. The dart is activatable downhole, such that it can be moved past tools similar to the target tool without actuating them. The target tool may include a release mechanism that releases the actuation dart after being actuate by it. Such a target tool may be useful with a second tool that retains the actuation dart against further movement down the tubing string.

Abstract: A method for opening a port through the wall of a ported sub including: providing a sub with a port through its tubular side wall; providing a hydraulically actuable valve to cover the port, the valve being actuable to move away from a position covering the port to thereby open the port; increasing pressure within the sub to create a pressure differential across the valve to move the valve toward the low pressure side, while the port remains closed by the valve; thereafter, reducing pressure within the sub to reduce the pressure differential; and driving the valve to move it away from a position covering the port.

Abstract: An adjustable and fixed inflow control device is provided. According to one embodiment, the adjustable inflow control device comprises a set of flow path walls defining a flow path that extends from an inlet to an outlet. The inlet may be open to the outer surface of a tubular and the outlet may be fluidly connected to an inner diameter of the tubular. The flow path may be adapted to control flow of fluid between the outlet and the inlet. The inflow control device further comprises a movable regulator that is movable to alter the flow path. The movable regulator may be movable between a number of positions. The inflow control device may be modular.

Abstract: A tubing string assembly is disclosed for fluid treatment of a wellbore. The tubing string can be used for staged wellbore fluid treatment where a selected segment of the wellbore is treated, while other segments are sealed off. The tubing string can also be used where a ported tubing string is required to be run in in a pressure tight condition and later is needed to be in an open-port condition.
