Abstract
A method of heating gas being produced in a well reduces condensate occurring in the well. A cable assembly having at least one insulated conductor is deployed into the well while the well is still live. Electrical power is applied to the conductor to cause heat to be generated. Gas is allowed up past the cable assembly and out the wellhead. The heat retards condensation, which creates frictional losses in the gas flow.
