METHOD FOR DEEP-EARTH HYDROCARBON FLUID INFLOW INTENSIFICATION Russian patent published in 2006 - IPC E21B43/00 E21B43/16 E21B43/27 

FIELD: oil and gas production industry, particularly methods or apparatus for obtaining oil, gas, water, soluble or meltable materials or a slurry of minerals from wells.

SUBSTANCE: method involves producing oil or gas from deposit by drilling production and injection wells; determining influx zone propagation in depth; creating favorable conditions to provide deep-earth hydrocarbon fluid inflow; drilling intensifying well in lower influx zone part; creating perforation interval from well bottom to mark located below productive formation bottom; bringing drilled intensifying well in operation along with creating bottom-hole pressure, which is limited by pressure at well head. Above pressure is determined from admissible produced oil degassing and stability of collector in perforated section of lower influx zone part.

EFFECT: increased hydrocarbon fluid inflow and provision of additional oil and gas production.
