Low salinity water injection
Low salinity water injection (LSWI) as a method of improving the oil recovery was first tested in the 60 s (Bernard 1967). Since then, significant research has been undertaken to develop a better understanding of the mechanisms behind LSWI that result in additional oil recovery. Meer weergeven Impact of potential determining ions (PDIs) Potential determining ions (PDIs) are those which can alter the crude oil/rock/brine interaction by altering the surface … Meer weergeven Various studies have indicated that the crudes that form micro-dispersion with water are good candidates for low salinity flooding as reservoirs with such crude-water system … Meer weergeven Rock dissolution (calcite) and fines migration have thought to be the possible mechanisms behind additional oil recovery using low salinity waterflooding. The calcite … Meer weergeven WebThe same low salinity water injection scenario of 14 years was performed by injecting 45,000 STB/D through six injection wells. Furthermore, the salinity of the injected brine is 3000 ppm, where both injected brine salinity and the reservoir salinity represented as total dissolved solids (TDS) in the simulation model using ECLIPSE black oil simulator.
