The goal of the Technological Complex.

The goal of creation of this technological complex is introduction of new technologies of petroleum production and increasing energetic efficiency of oil field development, search and involvement into development of weakly draining (by-passed) oil reserves, cost saving for petroleum production at the stage of pre creation of geologic and hydrodynamic models.

Essence of the Technological Complex.

The basis of the complex is rooted into “Recovery mechanism of the oil field” on Patent R.F. # 2044870 which allows to substantially increase the coefficient of efficient use of stratum energy and oil recovery by means of setting interrelated flow rates of oil and injection wells. This method practically doesn’t require additional production expenses and is efficient due to rational use of available field opportunities and stratum energy.

Applications and technological efficiency of “PETRA” Complex.

Technological Complex “Petra” was successfully applied at Samotlor, Lor-Yegansk, Nikolsk (JSC “TNK-Nizhnevartovsk”, Koshilskiy (JSC “NNP”), Savujskiy, Russkinskiy (JSC “Surgutneftegaz”) and Novo Purpeyskiy (JSC “Purneftegaz”) oilfields. In order to increase reservoir recovery, special programs have been worked out for these enterprises.

Expected annual technological efficiency of works at  JSC “TNK-Nizhnevartovsk comes to 221 thousand tons of additional oil production.
