Effectiveness of oil reservoir fracturing in case of high gas saturation

Authors: D.A. Garipova, V.V. Poplygin (Perm National Research Polytechnic University, RF, Perm)

Key words: oil reservoir, productivity factor, well, fracturing, bottomhole pressure, proppant.

The paper presents the results of hydraulic fracturing on the field with high gas saturation of reservoir oil. The geometric dimensions - volume of pumped fracture proppant relationship is shown. Wells operation conditions after hydraulic fracturing are plotted against these conditions before hydraulic fracturing. There was a sharp decrease in flow rates after fracturing in wells with low bottomhole pressure. The authors give several recommendations on selecting wells for hydraulic fracturing for examined layer and similar objects.
