Paper: USING POLYLINED TUBING IN A WEST TEXAS FIELD TO MITIGATE TUBING FAILURES A CAS HISTORY

Polyethylene lined (polylined) tubing has been in service throughout West Texas several years. This paper reviews the experiences of one field where use of polylined tubing began in 2000 in one well and was then extended to other wells in efforts to mitigate high tubing failures. The data contained here in reviews the pre and post tubing failure rates of the about 40 wells, and reviews the salvages of tubing in a few select wells discussing their reduction in lost tubing value per day. The improvement in well failures and the reduction in lost value are very significant offsetting the added material costs and handling problems associated with polylined tubing. But, the paper will also provided notes addressing some of those handling caveat gained from field experiences.
