METHOD FOR MULTIPAY FIELD SURVEY AND DEVELOPMENT Russian patent published in 2008 - IPC E21B47/10 E21B43/00 

FIELD: oil production, particularly to develop oil pool with porous fissured reservoir.

SUBSTANCE: method involves injecting flaw-detecting agent along with displacing agent into injection well at predetermined well head pressure, wherein the flaw-detecting agent has necessary concentration; recording flaw-detecting agent concentration in production wells. For that individual flaw-detecting agent having predetermined bottom pressure is injected in each reservoir of at least one injection well. Flaw-detecting agent concentration is recorded in production wells at corresponding reservoir outlet. After that main parameters of each reservoir, namely fissure (fissured break) presence, direction and volumes, as well as filtration rate, permeability, inefficiently injected water volume and hydrodynamic association of parameters are determined. Bottom pressure is changed during flaw-detecting agent injection at least for one injection well reservoir. Said process is continued up to reservoir parameter uncertainty elimination or up to optimal displacement agent injection pressure reaching.

EFFECT: increased information content and optimized reservoir pressure field.
