Abstract: Liner hangers and methods of use. An example method includes positioning a liner hanger in a wellbore; the liner hanger comprising: two sealing elements disposed on the exterior of the liner hanger and having a void space therebetween, and a pressure reducing metal element disposed between the two sealing elements. The method further includes trapping a wellbore fluid in the void space; wherein the wellbore fluid thermally expands in the void space creating an annular pressure in the void space; and reducing the annular pressure by materially altering the pressure reducing metal element.

Abstract: A downhole temporary pressure isolation tool configured to withstand very high gas pressures at high temperatures may be achieved by a variety of configurations, processes, and techniques. In particular implementations, a barrier valve having one or more frangible discs configured to resist fluid flow in a particular specified duration. In some implementations, the barrier valve may achieve a VO rating. In one embodiment, for example, a barrier valve may prevent the passage of fluid (i.e., gas and/or liquid) at 15,000 psi and a temperature of 400 degrees F for at least 15 minutes. If the barrier valve has two frangible ceramic discs, it may prevent the passage of fluid from two directions for at least 15 minutes.

Abstract: A method of seal condition monitoring may determine the state of the annular seal, the state of one or more sealing elements, take actions to maintain the annular seal as one or more sealing elements transition from new to worn, and provide advance notice of the impending failure of one or more sealing elements so as to avoid a catastrophic annular seal failure while the marine riser is pressurized. Advantageously, operations may be conducted proactively rather than reactively, and one or more sealing elements may be replaced well in advance of failure, but potentially later than a conventional maintenance schedule would dictate. The one or more failing sealing elements may be proactively replaced without depressurizing the marine riser, prior to seal failure or replacement may be planned well in advance and coordinated with other rig operations to improve efficiency and maintain the safety of the drilling rig and personnel.

Abstract: A guide assembly for a downhole tool and related method is disclosed. The guide assembly comprises a guide housing, flappers, and a driver. The guide housing has a passage to receive the downhole tool therethrough.. The flappers are movably positionable about the passage to selectively reduce an inlet thereto. The driver comprises a translator rotationally coupled to the flappers via the rods and an actuator to rotate the translator. The flappers are rotatable between the closed and the open position by the driver whereby passage of the downhole tool into the passage is selectively permitted. The translator may be a cam, gear, or rotary driver. The actuator may axially or rotationally drive the translator.

Abstract: An apparatus for introducing a drop ball into a well is provided. In one embodiment, the apparatus includes a wellhead assembly (14, 16, 52) mounted over a well (12) and a ball launcher (18, 62) for routing a drop ball (36, 94) into the wellhead assembly. The ball launcher includes a fluid conduit (64) coupled to the wellhead assembly and a pilot ball (92) disposed in the fluid conduit. The ball launcher also includes a stop (130) positioned in the fluid conduit to prevent movement of the pilot ball past the stop while allowing movement of the drop ball past the stop and into the wellhead assembly. Additional systems, devices, and methods are also disclosed.
