Over the last few years, material options for downhole tubing in water injection wells, particularly subsea wells where the cost of workover is prohibitive, have received considerable attention. A great deal of test and field experience demonstrates that the internal tubing coatings currently available do not have sufficient mechanical robustness to survive
mechanical damage occurring downhole. The mechanical damage aries from impact tool strike and wireline wear by the supporting wire. This
communication reports the results of a study of wireline wear on various coatings under laboratory conditions. Wireline wear was investigated bytwo means: (1) Reciprocating a loaded wire against the coating; (2) Rotating a wire beneath a loaded-coated pin, using a modified pin-on-disk apparatus. Keywords: wireline wear, polymeric coatings, water injection, pin-on-disk.
