COMPARISON FOR OIL RECOVERY BETWEEN WATER AND
the polymer flooding technique can increase oil recovery efficiency compared with the natural flow and water flooding techniques for the U-Thong oil field. There was an increase in the oil recovery efficiency over the natural flow and water flooding techniques to 28.98% and an increase to 5.75% of oil
Exploiting Water Injection Techniques for Increasing Gas
The primary value of water injection as a secondary gas recovery technique stems from the use of high water rates from nearby producing wells under aquifer drive, which would otherwise be shut-in. The technique can also be managed as a water disposal option for adjacent fields, thus reducing company expenditure on treating the produced water

is the least prevalent and is used in less than 1 percent of U.S. oil wells. This approach, also known as chemical flooding, uses solutions composed of micellar polymers and water to reduce the friction between oil and water. Like thermal recovery, this lowers the viscosity of the oil and increases flow.

Here, huge quantities of water are injected into the edges of a producing field to drive the oil (lighter than water) to a collection point tertiary recovery methods can use heat, steam, complex polymers, surfactants, and microbes to increase the recovery even further.
