METHOD OF DEVELOPMENT OF OIL DEPOSIT BY DEPOSIT HYDRAULIC FRACTURING Russian patent published in 2015 - IPC E21B43/26 

FIELD: oil and gas industry.

SUBSTANCE: method comprises deposit drilling by vertical, directed and/or horizontal wells, at that the reservoir deposit includes at least two production deposits or is stratiform, product recovery from deposits by the production wells, geochemical analysis of the produced oil, deposit hydraulic fracturing designing and execution. Tight rock layers separating the production deposits have thickness two meters maximum. After drilling wells are deposited for at least one year, during which with minimum interval once per month the geochemical analysis are performed for the produced oil of each well, based on the analysis results the star diagrams are plotted within chromatogramms nC₈-nC₂₀ range. In wells where area of one or several start ends decreases with time, or where start area at once differs by more than 10% of average area of the coincide start diagrams upon their imposition on each other, the hydraulic fracturing is designed and executed in vertical and directed wells, and in the horizontal well multiple hydraulic fracturing is performed, then wells are commissioned.

EFFECT: increased surface efficiency and increased oil recovery of the deposit.
