METHOD OF DEVELOPMENT OF OIL DEPOSIT Russian patent published in 1997 - IPC

FIELD: oil production. SUBSTANCE: deposit is developed by producing and injection wells. To ensure uniformity of advance of front of oil displacement from formation, injection wells are located in cutting rows whose directions coincide or is close to direction of large axis of deposit, and producing wells are located between rows of injection wells. As rows of injection wells are located in direction of maximum permeability in formation, flows of displacement agent from neighboring injection wells are joined to form common front of displacement which starts uniformly advancing to producing wells. EFFECT: higher efficiency.
