MPS REIS-R Gel Polymer Composition
To be used in technology of watering control of heterogeneous reservoirs at oil fields
COMPOSITION APPLICATION
- Watering control of heterogeneous, highly watered layers of carbonate and terrigenous reservoirs
- Increasing reservoir coverage ratio under exposure by changing directions of filtration flows, an agent injected into the reservoir
- Reducing permeability low filtration resistance channels
- Additional oil production from previously not drained areas of the reservoir
- Reducing operational costs for extraction of produced water
SUCCESSFUL APPLICATION
15-
26
IN AVERAGE THE INCREMENTAL OIL RECOVERY DUE TO CHEMICAL EOR PROCEDURES PER ONE WELL OPERATION MAY COME TO 4.6 TONS OR ABOUT 26% OF TOTAL PRODUCTION FOR THIS WELL
CHEMICAL COMPOSITION
- A mixture of water-soluble synthetic polymers and stabilizers
THE IMPROVED DISPERSION QUALITIES OF MPS REIS POLYMER COMPOSITIONS ENSURE MORE QUICK PROCESS OF REAGENT MIX-UP WITH WATER AND TO DISSOLVE THUS PREVENTING THE EFFECT OF “FISH EYE”
ADVANTAGES OF USAGE
- High filtration selectivity
- Adjustable gel forming time
- Adjustable hydrodynamic resistance
- Resistance to formation fluids
- Can be destructed by chemical methods
- Can reduce swelling of clays
- Increased stability over a wide temperature range and in mediums of varying degrees of aggressiveness
- Composition compatibility with waters of different mineralization
- Improved dissolving quality and dispersion properties of the composition formulation
APPLICATION TECHNOLOGY
- Continuous injection of the entire volume of the composition into the well
- Squeezing into the reservoir with water
- Exposure for a period of gel formation
- Well putting on production
