摘要： A superelastic metal seal for use in a downhole tool, wherein the superelastic metal seal may be formed from a superelastic Ni—Ti alloy. The superelastic Ni—Ti alloy may be prestrained with a permanent strain. Superelasticity may be imparted to the superelastic Ni—Ti alloy through a thermal treatment process or through prestraining the superelastic Ni—Ti alloy. The superelastic Ni—Ti alloy may exhibit superelastic behavior. The superelastic Ni—Ti alloy may not exhibit shape memory behavior.

摘要： An in situ method deploy and/or plasticize a shape-memory material in order to change the material's physical dimensions and/or mechanical properties, including a method for deploying a shape-memory polymer having a deformed or compressed shape in an environment at a first temperature, the shape memory polymer having a first glass transition temperature which is greater than the first temperature. The method also includes decreasing the glass transition temperature of shape memory polymer from the first glass transition temperature to a second glass transition temperature which is less than or equal to the first temperature; and expanding the shape memory polymer to deploy the shape memory polymer in a deployed shape.

摘要： Methods of using a component in a subterranean wellbore include positioning a component including a degradable thermoset polymer material in a wellbore location, obstructing flow with the component, exposing the component to an acidic solution to degrade the selectively degradable thermoset polymer material and to remove the component from the wellbore location, and flowing a fluid through the wellbore location where the component was positioned. Methods of forming a component of a wellbore system include forming at least a portion of the component to comprise a degradable thermoset polymer material. Wellbore systems include at least one component including a selectively degradable thermoset polymer material. The selectively degradable thermoset polymer material may be a polyhexahydrotriazine (“PHT”) material.

摘要： A method of forming a structure for a downhole application comprises forming an interfacial material comprising at least one of self-reinforced polyphenylene, polyphenylene sulfide, polysulfone, and polyphenylsulfone between opposing surfaces of a first substrate and a second substrate. A downhole structure and a downhole assembly are also described.

摘要： An electric submersible well pump assembly includes a pump and an electrical motor filled with a dielectric lubricant. A capsule extends around a portion of the motor, defining a chamber between the capsule and the motor. A port through a side wall of the motor communicates the lubricant within the motor to the chamber. Thermoelectric devices are located within the chamber. Voltage supplied to the thermoelectric devices cools the lubricant.
