METHOD OF JOINED DEVELOPMENT OF OIL AND POTASSIUM DEPOSITS Russian patent published in 2005 - IPC

Abstract RU 2244107 C1

FIELD: mining industry.

SUBSTANCE: invention comprises following scheme. Oil is produced from producing wells. Potassium salts are extracted from mines and processed. Solutions are pumped into deep lying porous rock formations preliminarily revealed between oil-bearing and potassium formations. Those porous rock formations are chosen which are located below underlying stone salt. Pumping of solutions is effected through injecting wells until pressure drop in oil-bearing formation is compensated to a value sufficient to prevent deformation in potassium formations, this value being calculated using special math formula. Oil formation is then run while maintaining compensating pressure in chosen porous formation.

EFFECT: significantly reduced environmental loading and increased safety of mining operations.
