With operating costs playing a larger and larger role in the economics of producing a well, optimizing equipment selection by means of an efficient artificial lift system is critical in reducing operating costs for a given field.

Six wells in Carter County, Oklahoma utilizing three different methods of artificial lift were looked at to compare overall system efficiencies between each method. Progressing cavity, reciprocating, and electric submersible pumps were compared on a per barrel of fluid produced basis and the electrical power usage converted to kw-hr/hr.
