Increasing life times of sucker rod pumps

As the oil-price and the US Dollar have been going down within the past years and production becomes more and more complicated it is necessary to reduce production costs. The cooperation between different departments led to a great progress in minimizing well-failures and therewith service life of sucker rod pumping increased. Starting from statistics on service life and failure some technical measurements are presented and discussed with regard to their efficacy. These include: sucker rod pumping (corrosion-resistant materials, appropriate use of piston and barrel, sand wiper, gaslock breaker), sucker rods (use of high strength sucker rods-grade D instead of grade C-, use of sinker bars, exploration of wear of sucker rods caused by different sucker rod couplings and rod guides), tubings (tubings made of J55 quality are normalized after the upsetting action by the producer according to an internal company specification, installation of glass-fiber-reinforced-tubings, test of tubing-rotators) and reservoir fluid (change of corrosion inhibitor after careful tests in laboratory and field, more efficient control of paraffin through hot water and liquid hydrocarbons).
