Planar fracturing and development of petroleum reservoirs

Research output: Contribution to journalArticle

Abstract

The research is relevant in the context of improvement of oil and gas recovery in low-permeability clastic reservoirs and shale. The main aim of the research is to substantiate the use of planar fracturing to improve oil and gas recovery in low-permeability clastic reservoirs. The research is based on a correlation between currently available theoretical developments on planar fracturing and practi- cal data obtained with petroleum geology, lithology and seismology of upper Jurassic and lower Cretaceous formations in West Siberia. Research methods: determination of the planar fracturing system with seismic survey (Prony's method), observation of the oriented core fracturing, lithologic and petrographic research of rock formations density zones, analysis of the reservoir production capacity in its expected zones of planar fracturing. Results. The author has analyzed Igolsk oilfield J12 reservoir development. The paper demonstrates the interconnection of the increased rates with rock formation density zones, determined by the seismic survey. The author correlated the density zones with the orientation of the planar fracturing system in upper Jurassic formations in West Siberia. The relation between the fracturing and the reservoir inter- vals of high clay content are introduced with lithology research data. The author compared the orientations of the global density field for Devonian-Carbon deposits in North America and the field of distribution of microseismic researches obtained at hydraulic fracturing of Low-Carbon shale formation Barnet. It was shown that the seismic activity area was formed by multiple regions of microseisms in northern-east and northern-west orientations which correspond to the predicted directions of rotating field global densities of the con- sidered stratigraphic horizon in this region by the literary sources.
