This article presents results from comparative laboratory tests of three internal plastic coatings used by one oil company for corrosion control in gas well tubulars. Prior to the testing program, coated tubulars from three different applicators were provided by supplier warehouses as equivalent materials for use in sweet gas well service. Coatings evaluations included autoclave, rocker arm, acid resistance, and wireline abrasion testing. Tests were designed to compare coating performance under harsh conditions such as high water production or high-temperature, high-pressure conditions. This was done to accelerate the testing program and also to identify any superior product(s). Test results showed that the three coatings were not equivalent, and that each coating had strengths in certain environments.
