PROCEDURE FOR DEVELOPMENT OF OIL DEPOSIT Russian patent published in 2011 - IPC E21B43/20 

FIELD: oil and gas production.

SUBSTANCE: procedure consists in withdrawal of oil via producers, in pumping working substance through pressure wells and in hydro-dynamic analysis of wells. At hydro-dynamic analysis of wells there are found pairs of the nearest wells - pressure well -producer without hydro-dynamic link. Lines of change of benchmark level are charted in the region of the found wells. The benchmark levels are analysed in the found wells. In case of sharp difference between benchmark levels there is established presence of a geological screen between the wells, so each singled out well is related to different sections of development. As a benchmark there is chosen the benchmark of sediments exposed below a basic producing bed of the developed deposit and the nearest to sediments of a crystallised foundation.

EFFECT: raised efficiency of prospecting deposits of oil inside developed deposit and of dividing deposit to sections according to hydro-dynamic link existing between wells.
