Biosurfactant Enzyme for Recovery of Oil (LKS-BERO) is one of the leading worldwide products for MEOR. It is a bio-enzyme with non-activity preparation and water soluble. It has strong powerful ability in releasing the hydrocarbon (oil) on the surface of reservoir rock particles. It quickly peel off the crystal substances, paraffin, asphaltenes on the rock particles after injected into the reservoir.
The reaction of LKS-BERO is a biological reaction; it’s different than the effects of chemical and bacterial. It will be directly effective to the pollutants, but it won’t change the characters of the crude oil. It can absorb on surface of the rock tightly and keep humid of rock surface. Therefore, the BEROTM Enzyme has high stability, congenital advantage adaptability for a long time. Theoretically, it would not be depleted.
1. Add BERO to the current fracturing fluid system to improve the effect of fracturing and increase the production.
2. In the later period of Waterflood, the water injection rate decrease as the injection pressure rise. Injecting BERO into the formation from injection well could reduce the injection pressure, thus the injection rate could rise.
3. BERO could replace chemical flooding in the tertiary recovery. Inject BERO into the formation from injection well to change the rock’s wettability, improve oil’s flowing.
4. Acid could remove the inorganic plugging and increase production. BERO huff and puff could remove the organic plugging, change the rocks’ wettability and increase production.
