  • Patent number: 10829997
    Abstract: An earth-boring tool for removing subterranean formation material in a borehole comprises a tool body having a central axis defining an axial center thereof and a leg extending in an axial direction from the tool body. A bearing assembly is removably coupled to the leg and includes a bearing shaft and a base member. The base member encircles a portion of the bearing shaft and abuts against a surface of the leg. A roller cone is rotatably coupled to the bearing assembly and has a rotational axis about which the roller cone rotates on the bearing assembly when the roller cone removes subterranean formation material in the borehole. A method of assembling a rotatable cutting structure assembly including the bearing assembly includes coupling the bearing shaft to the leg by disposing a mechanical fastener through an aperture formed through the leg and into a cavity of the bearing shaft.

  • Patent number: 10808486
    Abstract: A hanger system for providing sealed passage for cables, lines, tubes or the like through a wellhead is provided. The hanger has a main seal formed to receive and provide sealed pass-through of power and control cables, lines, conduits, or other threaded components therethrough, while effectively packing off and sealing the well bore. The hanger is provided with hinged side doors formed to engage and support the components. When the hanger with threaded components is positioned to rest in the bowl of the tubing head, the lower string weight is utilized to compress the main seal, providing an effective seal. The present system is suitable for use with permanent as well as temporary applications, and is designed to provide a low to medium pressure seal. Also taught is a bowl cap with compression seal to cover the present system, while providing enhanced, sealed pass-through.

  • Patent number: 10794179
    Abstract: A method for obtaining hydrocarbon from a reservoir in a subterranean formation can include measuring a poromechanic pressure change due to lithostatic load sharing in the subterranean formation. The poromechanic pressure change can then be mapped to one or more locations within the subterranean formation. Once mapped, the method can identify one or more local pressure peaks in the poromechanic pressure change, wherein each of the one or more local pressure peaks are marked by a pressure escalation and subsequent pressure depletion. The method can then determine one or more regions within the reservoir exhibiting single phase hydrocarbon production.

  • Patent number: 10787889
    Abstract: For gas lift, gas lift valves install on a completion in a wellbore. The gas lift valve has a pressure-sensitive valve and a check valve configured to control communication in the valve. A piston is held closed with a first connection relative to the valve's outlet exposed to tubing pressure, while the check valve is held open in the valve with a second connection. Pressure testing can be performed on the integrity of the tubing and casing by increasing the tubing and annulus pressures while the piston stays closed. The gas lift valve is then actuated for operation by increasing the tubing or annulus pressure beyond a predetermined limit of the first connection to release the piston to move open relative to the outlet. The movement of the piston releases the hold of the second connection on the check valve so the check valve can function normally as a one-way valve.
