摘要： A method for enhancing the flow of heavy crude oil by heating a subsea pipeline is disclosed in which a pipe-in-pipe subsea pipeline is established having a flowline for transporting well fluids in the form of an electrically conductive inner pipe concentrically surrounded by an electrically conductive protective outer pipe and the inner pipe is electrically insulated from the outer pipe along the length of the subsea pipeline. The pipe-in-pipe subsea pipeline is electrically heated continuously along its length to maintain the temperature of crude oil at a level facilitating pipeline transportation, this heating comprising passing alternating electrical current along the exterior surface of the inner pipe and along the interior surface of the outer pipe. In this manner the crude oil can be maintained at a temperature at which viscosity does not prevent efficient and economical pipeline transport.

摘要： An insulated conductor heater may include an electrical conductor that produces heat when an electrical current is provided to the electrical conductor. An electrical insulator at least partially surrounds the electrical conductor. The electrical insulator comprises a resistivity that remains substantially constant, or increases, over time when the electrical conductor produces heat. An outer electrical conductor at least partially surrounds the electrical insulator.

摘要： A system used to heat a subsurface formation includes an elongated heater at least partially located in an opening in a hydrocarbon containing layer of the formation. The opening extends from the surface of the formation through an overburden section of the formation and into the hydrocarbon containing layer of the formation. The elongated heater includes an electrical conductor, an insulation layer at least partially surrounding the electrical conductor, and an electrically conductive sheath at least partially surrounding the insulation layer. The elongated heater tapers from a larger thickness at a first end of the heater to a smaller thickness at a second end of the heater. The first end is at or near the junction between the overburden section and the hydrocarbon containing layer and the second end is further into the hydrocarbon containing layer.

摘要： A method is disclosed for pipeline leak detection in which a vacuum is maintained in the annulus of a pipe-in-pipe flowline with a vacuum pump having a discharge reservoir which is monitored for the appearance of water and hydrocarbon vapors. In another aspect of the invention pipeline leak detection is accomplished through maintaining a gas at a nominally constant pressure in an annulus of a pipe-in-pipe flowline and monitoring the annulus for pressure increase indicative of water or product intrusion into the annulus.
