METHOD OF DEVELOPMENT OF SHALLOW LOW-YIELD OIL DEPOSITS Russian patent published in 2008 - IPC E21B43/20 

FIELD: oil and gas industry.

SUBSTANCE: suggested method refers to oil producing industry and can be employed at development of low-yield deposits. The essence of the invention is as follows: the method of development of shallow low-yield oil deposits in which prospecting wells have been bored incorporates boring producing wells, withdrawal of oil from producing wells and individual water pumping into pressure wells to maintain pressure in oil reservoirs, then displacement of oil into the direction of producing wells. According to the invention before boring of producing wells the map of oil areas with bored prospecting wells is overlaid with a base uniform square well location map. After that wells are bored according to the base map near the existing prospecting wells. Hydrodynamic investigations of bored wells are performed and in case of confirmed productivity of oil reservoirs a rational integration of reservoirs into operational sites is performed under condition of increase of medium well yield. The following wells are bored also according to base uniform square map till forming self contained operating cells of wells from bored and hydrodynamic investigated wells with allocating pressure wells in them. Efficiency of individual pumping water into pressure wells in these cells is determined on base of efficiency of surrounding producing wells.

EFFECT: increased efficiency of low-yield deposits development.
