This paper documents 8 years of performance of an improved artificial lift system installed in a secondary recovery project. This improved artificial lift system matches a Fiberglass-Sinkerbar rodstring design to a specific pumping unit installed with a Pump-off Controller. Fiberglass-Sinkerbar rodstring designs have been given little or no consideration concerning reduced downhole rod and tubing failures or power consumption costs. The success of this improved artificial system has led to the following improvements in field performance: 1.Increased lift capacity from 20 cmpd (126 bfpd) to 100 cmpd (629 bfpd) 2.Runtimes between failure in excess of 1450 days (4.2 years) 3.Reduced power costs from .070 to .061cents/barrel 4.Lower operating expenses due to reduced power consumption, reduced maintenance costs and less downtown. Utilization of this improved artificial lift system will increase lift capacity, reduce downhole failures, increase runtimes and reduce power consumption and related expenses
