... to the successful implementation of three common modes of topside treatment of paraffin deposition; steam treatment, annular chemical injection, and periodic batch treatment. It will also compare the return on investment associated with these successful applications. In this present economic climate...

... was a constant. Wells failed continuously caused by rod wear, sand production, paraffin deposition and also subsurface pump valves wear, resulting in a failure frequency of 0.810 failure/well-yr. Sucker rod pumped wells have been produced from the shallow Eocene reservoir since 1924. The current average...
