Distribution of oil-saturated thicknesses.
A pilot site, AB 4-5, Samotlor.

Distribution of by-passed oil zones in the
watered part of the reservoir. AB4-5, Samotlor.

In 1997 a silver medal was awarded to this technology at the 46 World Innovation Exhibition of Scientific Investigations and New Technologies in Brussels.

The goal of the Technology.

Increase of current oil recovery.

The Essence of the Technology.

- the pattern of current oil reserves (oil saturated bulk) distribution at the site is determined;

- extraction of the oil reserves by means of focused and adequate level of concentration of coercing resources is provided from the direction of producing and injecting wells.

- transitional coercion and change of seepage course from the direction of injecting wells are realized.

Sites for the Technology Application and Technological Efficacy.

The technology underwent full scale approbation by means of field experiments at experimental ground of AB4-5 (1992-1996) site and by practical application at the development of Samotlor oilfield  (sites АВ4-5 and BV81-2 ), since 2000.

Results of Field Experiments at the Experimental Site of AB4-5 Layer, Samotlor.

- Increase of the current oil extraction up to 2.9 times (from 29.8 thousands to 86.5 thousand tons)

- Decrease of water-oil factor up to 2.6 times (from 40.2 to 15.3 t/t)

- Water cut decrease up to 3.7% (from 97.6% to 93.6%)

- Increase of liquid flow rate for 1.59 and oil production up to 3.85 times.

Results of Industial Application of Technologies at  АВ4-5 and BV81-2  sites of Samotlor Oilfield in 2000.

- Increase of  liquid flow rate per one oil well came to - 118 м3/d

- Increase of oil production per one oil well came to – 4.8 t/d

Total additional output in the course of the Technology implementation from January 2000 to August 2001 came to 493 thousand tons of oil.
