Abstract: A seal assembly for a submersible pumping system is presented. The seal assembly includes a housing and a support tube disposed within the housing. Further, the seal assembly includes a shape memory alloy (SMA) foil disposed within the housing, surrounding the support tube to define a first chamber between the shape memory alloy foil and the support tube. The first chamber is configured to store a motor fluid, and wherein the shape memory alloy foil is configured to restrict a flow of a wellbore fluid to the motor fluid.

Abstract: A sealing system for a multi-stage turbine includes multiple first interstage seal subsystems disposed circumferentially about a rotor wheel shaft of the multi-stage turbine and extending axially between a first turbine stage and a second turbine stage of the multi-stage turbine. Each of the first interstage seal subsystems includes multiple near flow path seal segments. The first interstage seal subsystem also includes a forward coverplate disposed axially between a first turbine wheel of the first turbine stage and the near flow path seal segment and an aft coverplate disposed axially between the near flow path seal segment and a second turbine wheel of the second turbine stag. Further, each of the forward coverplate and the aft coverplate extends radially to a first stage bucket and a second stage bucket respectively.

Abstract: A sealing system for a multi-stage turbine includes multiple interstage seal segments disposed circumferentially about a turbine rotor wheel assembly and extending axially between a forward turbine stage and an aft turbine stage. Each of the interstage seal segments includes a forward end portion including an outer seal surface and an inner support face, an aft end portion, including an outer seal surface and an inner support face and a main body portion extending axially from the forward end portion to the aft end. The main body portion includes at least two support webs coupling the outer seal surfaces and the inner support faces. The outer seal surfaces are configured to be retained in a radial direction by a land support on each of a forward and aft stage turbine buckets, such that substantially all the centrifugal load from the multiple interstage seal segments is transferred to the forward and aft stage turbine buckets. A method of assembling the sealing system is disclosed.

Abstract: A gas lift valve assembly includes a housing and a check valve. The housing defines an inlet port and an outlet port, and includes an inner casing having a radial outer surface and a radial inner surface at least partially defining a main flow passage. The check valve includes a sealing mechanism disposed around the radial outer surface of the inner casing, and a valve member including an outwardly extending sealing segment. The valve member is moveable between an open position and a closed position in which the sealing segment sealingly engages the sealing mechanism.
