Patent ID: 7032658

Claim:
A method of providing artificial lift to produced hydrocarbons within a subsea flowline comprising at least the steps of: (a) attaching a progressing cavity pump to an electric motor to make an electrically energized pump; (b) attaching said electrically energized pump to to a first end of a tubular composite umbilical possessing a multiplicity of electrical conductors within the wall of said tubular composite umbilical; (c) conveying into said flowline said electrically energized pump attached to said first end of said composite tubular umbilical; (d) using first and second of said multiplicity of electrical conductors to electrically heat said composite umbilical to prevent waxes and hydrates from blocking the flow of said produced hydrocarbons within said flowline; and (e) using at least third and fourth electrical conductors of said multiplicity of electrical conductors to provide electrical energy to said electrically energized pump, whereby said progressing cavity pump provides artificial lift to said produced hydrocarbons within said subsea flowline.
