A study was initiated to establish a uniform method of removing paraffin from wells completed in the San Andres formation in Hockley and Cochran Counties, Texas. Several methods of paraffin removal, including hot-oiling, batch treating with chemical, paraffin inhibitor squeezes, and batch treating with paraffin-eating bacteria, were evaluated and the results reported. Each year thousands of dollars are spent removing paraffin from tubing and flow lines in San Andres wells. The best methods for optimizing paraffin removal while minimizing lease expense will be discussed.
