Wells which produce "heavy oil" often present some of the most difficult pumping conditions incurred within the industry. However, the Conn Pump & Eagle Solution Valve with its greater cross-sectional area, has demonstrated dramatically favorable results under these same conditions. Production has been increased form 15% to 60%, as compared to pumps with conventional travel valves acting alone. This performance also indicates a signif¬icant improvement in the fluid dynamics prevalent within the pump chamber itself. By minimizing pressure drop across the entire valve system, all valves are able to open and close much more quickly and smoothly.

When compared to other pumping systems, tests performed in difficult heavy oil applications consistently demonstrate that the improved technology of the Conn Pump with the Eagle Solution Valve resulted in significant reductions in lifting costs and increases in oil production.
