REDA Maximus ESP System for Severe Service Extends Run Life by 550% in Corrosive Wells, Western Canada

Publication Date: 11/10/2017

When depleting the oil reservoirs in the South Sturgeon Lake region, well production often changes from sweet to sour condition, containing hydrogen sulfide and carbon dioxide. The highly corrosive fluid compromises run life in conventional ESPs, leading to premature failures. An operator in the field asked for an ESP system that could withstand the corrosive operating condition and therefore improve oil recovery and ESP run life. Schlumberger designed a Maximus ESP system for severe service to extended run life, improve cost of ownership, and eliminate workovers to replace pumps.
