Abstract: A system for use in hydrocarbon production includes a well that has a wellhead and extends downhole into a reservoir. The wellhead has a passageway that extends through a sidewall thereof. The system includes piping extending from the wellhead at the passageway. A downhole electrical device is disposed downhole in the well. A cable is coupled to the downhole electrical device and includes electrical wires extending from the downhole electrical device, out of the wellhead, through the passageway in the sidewall, and along the piping. A cooling section is disposed along the piping through which the electrical wires pass, and an electrical connector is coupled to the electrical wires for electrical connection thereto such that the wires extend along the cooling section between electrical connector and the wellhead.

Abstract: A process includes injecting mobilizing fluid, including a solvent, through an injection well and into a hydrocarbon-bearing formation. Fluids are produced from the hydrocarbon-bearing formation to a surface through a well, and injection of the mobilizing fluid is discontinued. Gas flow to the surface from the well is inhibited by injecting a loss circulation material that inhibits solvent-vapor flow from exiting the formation through the well such that a fluid column that includes the well kill fluid, the loss circulation material, or a combination thereof is maintained within the well. The well is opened to perform work thereon After degradation of the loss circulation material, injecting the mobilizing fluid and producing the produced fluids is commenced.

Abstract: A process for producing fluids from a subterranean hydrocarbon-bearing formation includes injecting mobilizing fluid, including a solvent, into the hydrocarbon-bearing formation through an injection well and into the hydrocarbon-bearing formation, producing produced fluids from the hydrocarbon-bearing formation to a surface through a production well, discontinuing injecting the mobilizing fluid and injecting a loss circulation material and a fluid into one of the injection well and the production well, opening the one of the injection well and the production well to perform work on the one of the injection well and the production well, and closing the one of the injection well and the production well. After degradation of the loss circulation material, injecting the mobilizing fluid and producing the produced fluids is commenced.
