Paper: HDPE Tubing In Rod Pumped Wells

Production tubing string failure and rod failure contribute significantly to the lifting cost of some wells produced by rod pumping and in some instances, may even be a determining factor in the decision to discontinue producing a well. This paper deals with the design, installation and field testing of a polyethylene liner for production strings in rod pumped wells. The paper reviews the causes of rod and tubing failure in production strings of wells produced by rod pumping, suggests polyethylene lining as a possible solution for those failures, and provides details, through a case history, of the results of field testing.
