METHOD OF CARBON DIOXIDE RECOVERY IN AQUIFER Russian patent published in 2014 - IPC B65G5/00 E21F17/16 

FIELD: oil-and-gas industry.

SUBSTANCE: invention relates to environmental protection against man-made contaminants, hothouse gases and power source synthesis. In compliance with proposed invention, this method comprises isolation of aquifer with, preferably, with cropout and feed area as, for example, a river, lake, sea with total active filtration conditions. At least one local trap is isolated in isolated bed. Selected aquifer and local trap are prepared for commercial use with definition of isolated aquifer water chemical composition and that of rocks by core sample. Carbon dioxide is injected to isolated aquifer via one injection well located on aquifer feed zone side to allow downstream of injected carbon dioxide in aquifer. Catalytic reaction of polycondensation synthesis of injected carbon dioxide and water to form hydrogen, oxygen and methane homologues.

EFFECT: higher efficiency of recovery for replenishment of hydrocarbons stores and development of new oil and gas deposits.
