Sucker-rod-pumping failures in the Permian Basin
Sucker-rod pumping is the most-widely-used artificial-lift method in the Permian Basin, one of the largest petroleum-production basins in the U.S. Data from approximately 25% of the sucker-rod-pumped wells in the Permian Basin were analyzed. Analysis shows that different companies use different operations-management and data-manipulation methods. The trend of yearly failure frequency is decreasing among the participating companies, but pump-failure frequency is the largest problem. The tubing also experiences a fairly high failure frequency. Recently purchased wells showed higher-than-normal failure rates followed by dramatic improvements. Recent reduction or addition in manpower showed increasingly higher-than-normal failures or dramatic reduction in failures, respectively.
