DEVELOPMENT METHOD OF OIL DEPOSITS USING FORMATION HYDRAULIC FRACTURING Russian patent published in 2013 - IPC E21B43/20 

FIELD: oil and gas industry.

SUBSTANCE: method involves construction of injection and production wells, carrying-out of directional hydraulic fracturings so that hydraulic connection is provided, pumping of displacement agent to injection wells so that uniform front of high pressure is provided in rows of injection wells, and takeoff of fluid from production wells. With that, directional hydraulic fracturings are performed only in rows of injection wells. In production wells there made is an analysis of the product flooding rate, as per which flooding maps are built and configuration of front of oil displacement with water is determined. Besides, in different injection wells arranged in rows there changed are volumes of pumped displacement agent to provide uniform high-pressure front.

EFFECT: possible in-line control by moving the front for oil displacement with water; excluding the risk of premature flooding of production wells with pumped-in water.
