In the Dickinson Heath Sand Unit waterflood, corrosion-related failures of coated injection tubing began accelerating in 1979 with the increased water production attributed to waterflood response. The trend peaked in 1984 when $164,000 was spent pulling failed tubing (34 workovers). Starting in 1983, the selection of coatings, coating-application-process quality control, and handling/installation procedures were examined, modified, and refined. The author discusses how these changes and improvements resulted in fewer pulling jobs and less money spent on associated workovers during 1988.
