The start-up completion scheme at the CO2 source wells in southwestern Colorado (McElmo Dome) specified tubing that was internally plastic coated (IPC). Most of the tubing was coated with a thin film phenolic and a limited amount of tubing was coated with a thick film epoxy-phenolic. Ryton* (polyphenylene sulfide) was applied to the center J-section of the couplings. The experience of trying to attain quality control from the coating applicators precipitated the development of coating specifications. The highlights of both the quality control of the coating applicators and the coating specifications which evolved are presented. Additionally, the production experience gained with the IPC tubing, which resulted in corrosion failures, is also reported. Production histories and photographs of the failures are included. The corrosion failures resulted in a change from IPC tubing to stainless steel tubing.
