Optical Particle Counter Verification of Particle Concentrations in Filtered Seawater for Injection into Oil Reserves
Seawater injection is a secondary recovery technique used in oil reservoirs to replace extracted oil and maintain well pressure. Oil reservoirs are typically found within the small pores of sedimentary rock formations, so it is imperative that the injected seawater does not contain suspended particle matter that can clog these pores and hinder oil recovery. Since untreated seawater contains significant quantities of suspended particle matter it is generally filtered prior to injection into oil reservoirs. Optical particle counters offer an accurate and reliable solution to quantify particle concentrations in filtered seawater used for injection.
