Abstract
Abstract A study was made of completion practices and corrosion control measures for gas wells with tubing pressures in excess of 5000 psi. A survey of 12 producing companies was made to determine what had been done to combat the problem. This paper reflects the results of this survey and includes data collected from 166 wells. Topics discussed include design problems in well installation, treatment with corrosion inhibitors, corrosion inhibitor efficacy evaluation, well characteristics, casing and tubing programs, and inspection methods. Data are given by company on the number of P-grade casing and tubing failures in service in well, failures occurring during hydrostatic tests, percent rejects of inspected pipe, and cost of failures of casing and tubing. 8.4.2
