ESP Pumping

Electrically powered submersible pumps have long served as the answer to secondary recovery challenges in wells with potentially higher flows, that those commonly observed in rod pumping applications. However, the same basic problems remain when considering the damage cause by intrusive particulates in the well bore and in the pump itself. It has been reported that fully 25% of all the electric submersible pumps in service worldwide are damaged by sand. Generally this is evident in a much shortened run life, as compared to its design criteria. Sometimes the pumps are destroyed completely. As higher production demands place an ever-increasing load on the pumps, the need for a dependable, long lived pump intake sand control solution has become more and more important.
