Abstract:
A method of heating gas being produced in a well to reduce condensate occurring in the well, comprising:(a) providing a cable assembly having at least one insulated conductor; (b) coiling the cable assembly on a reel and transporting the cable assembly to a well site; (c) deploying the cable assembly from the reel into the well while the well is still live; (d) applying electrical power to the conductor to cause heat to be generated; and (e) flowing gas up past the cable assembly and out the wellhead; wherein step (a) comprises inserting an electrical cable into a string of coiled tubing to form the cable assembly, providing an inner annulus within the coiled tubing between the cable and the coiled tubing; and the method further comprises placing a liquid in the inner annulus to increase heat transfer from the cable to the coiled tubing.
