Secondary Recovery Pumps

Industrial Duty Pumps & Accessories for Secondary Recovery Applications



This process is used when an oilfield's reservoir pressure has been depleted and is no longer sufficient to aid in the pumping process. Water is injected into the well to maintain reservoir pressure and push oil toward the production well. Secondary recovery includes wastewater re-injection, low salinity flooding, and can use any source of bulk water available.

Wastewater re-injection is a standard method for secondary recovery. Oil wells bring up large amounts of saltwater when the oil is being pumped, rendering "produced water," the majority of which consists of salt or brackish water (also called oilfield brine). After the oil and brine have been separated, saltwater is injected back into the oil reservoir. This method allows for wastewater disposal while increasing pressure in the reservoir and helping oil flow toward the production well.

Cat Pumps reciprocating triplex pumps are ideal for secondary recovery because of our proven reliability in continuous-duty applications. We offer Brass, Nickel Aluminum Bronze, 316 Stainless Steel, and Duplex Stainless Steel Pumps to work with any water. Cat Pumps specializes in custom-built systems (pump, motor/engine, pressure controls, base, etc.) designed to meet the application's needs.

With field-proven dependability in applications around the globe, Cat Pumps provides the best value for secondary recovery systems.
