Investigation of the Influence of Pressures and Proppant Mass on the Well Parameters after Hydraulic Fracturing

This paper considers the implementation of hydraulic fracturing in an oil field located Arkhangelsk region Russia. During exploitation, production rates and injectivity injection wells were intensively decreased. To increase well flow rates, formation was carried out, evaluation efficiency performed. Oil after increased 3.2 times productivity index twice. The influence geometrical sizes fractures on volume injected proppant investigated. An mass from 2 to 3 tons per 1 meter thickness leads average crack width by 0.5 mm, half-length 40 m. Well work parameters a reservoir obtained as function original reservoir. It observed that there is sharp decrease with low bottom hole pressures. When pressure at decreases 60 20 MPa, it 50 m.  Direct correlation between coefficients values pressures observed. optimal conditions for identified, which made possible significantly operation.
