Digital core simulator - a promising method for developming hard-to-recover oil reserves technology

V.B. Betelin, V.A. Galkin, A.V. Shpilman & N.N. Smirnova
Territory of Russia, which occupies 12.8% of the Earth's territory, contains 12-13% of the forecast resources, and about 12% of the discovered oil reserves. Russia's proven oil reserves amount to approximately 13.9 billion tons of oil as of January 1, 2017 (~101 billion barrels). Oil recovery factor for proved reserves is ~17%. The increase of oil recovery factor represents a huge stockpile for raising the level of oil production in the country at low costs....

AN APPROXIMATE ANALYTICAL SOLUTION FOR HYDRAULIC FRACTURE OPENING UNDER NON-UNIFORM INTERNAL PRESSURE

Kairui Li, N.N. Smirnov, D.A. Pestov, Chengzhi Qi & A.B. Kiselev
Because of the special non-uniform pressure distribution in hydraulic fracture, an especial hypothesis is proposed to get an approximate solution for the fracture opening, which satisfies the mixed boundary conditions on the fracture edges with the use of Bessel function integral properties. Error analysis of this approximate solution compared with the accurate solution is carried out. It is proved that the approximate solution is in good agreement with the accurate solution under the condition of...
