Investigation of Wettability Alteration by Low Salinity
MICROBIAL ENHANCED OIL RECOVERY WITH RHODOCOCCUS SP. 094 Crescente, C.1, 2, and contact angles was carried out to test the effect of wettability and salinity on Microbial Enhanced Oil Recovery (MEOR). 14 water wet and 15 mixed wet bacterial flooding after waterflooding to SorWF were carried out, showing the importance of the distribution of the residual oil. Water wet cores would leave …... 6/01/2012 · I generally do a water change and add back the water that will help drop, or raise, to what I need. So you could simply pull out a gallon of salt water and add back a gallon of RODI. What a bit and do it again until you get the result you are looking for. I'd …

Salinity of injection water and its impact on oil recovery

Wettability alteration triggered by the change in interfacial tension (IFT) between crude oil and low salinity surfactant (LSS) is known to be the main factor regarding EOR processes....
This calculator takes the amount of water in your system, your current salinity, the salinity you'd like to achieve, and the maximum change in salinity that you are willing to risk per water change.

How To Lower Salinity Change Wettability

Summary. Low salinity water injection is an emerging EOR technology, applicable to mixed-to-oil-wet sandstone reservoirs. Flooding with low salinity water causes desorption of petroleum heavy ends from the clays present on the pore wall, resulting in a more waterwet rock surface, a lower remaining oil saturation and higher oil recovery.

  • The change over the past 50 years has been about 0.2 psu (practical salinity units) which is about 0.5 percent." The Atlantic normally is saltier than the Pacific, mostly because the trade winds blow evaporated, salt-free water from the Atlantic to the Pacific, mostly at the Isthmus of Panama.

  • Sr2+ concentration was lower. Therefore, applying LSWF containing SO 4 2-ion to carbonate oil reservoirs is not always a desirable EOR method when Sr2+ is present, as an impurity, in the formation water. Keywords: Low-Salinity Water, Sr2+, Precipitation, Permeability, Wettability, Carbonate reservoir. 1. Introduction About 60% of oil is reserved in carbonate oil reservoirs and more than 80% of
  • Salinity is typically measured as a concentration of grams of salt per kilogram of water (g/kg). This quantity is equal to the measure of parts salt per thousand parts water (ppt).
