Abstract
A method of producing fluids from a well bore by polishing the inside diameter surface of a down-hole tubular. The method includes the steps of providing a down-hole tubular having an inside diameter and being made of a carbon steel alloy or a high chromium alloy, preparing an inside diameter surface of the down-hole tubular, subjecting the inside diameter surface to an electropolishing treatment to produce a smooth surface being slick and essentially non-stick, locating the down-hole tubular within the well bore adjacent a fluid-producing formation, and producing the fluids through the inside diameter of the down-hole tubular. The electropolishing treatment can also be applied to the inside diameter surfaces of carbon steel drill pipe.
