METHOD OF OIL DEPOSIT DEVELOPMENT ACCORDING TO BLOCK SYSTEM Russian patent published in 2009 - IPC E21B43/20 

FIELD: oil and gas production.

SUBSTANCE: invention refers to oil industry and can be implemented at development of oil deposits with changeable oil saturated thickness. The essence of the invention is as follows: the method consists in delineation of deposit with sections and in delimitation of blocks with oil saturated thickness to 5 m, from 5 to 15 m and over 15 m. For each interval of oil saturated thickness there is determined its own set of oil deposit development processes facilitating maximum oil yield at given oil saturated thickness. Also development of oil deposit is carried out in blocks in each delineated section using its own process applicable to each interval of oil saturated thickness.

EFFECT: facilitating increased oil yield of non-uniform in zones deposit, ie deposit with changeable in area oil-saturated thickness on different sections.
