Computer Geological Simulation in Oil Recovery

At the Siberian Scientific-Research Institute for the Oil Industry we have developed some methods of solving geological problems. They are realized in the form of a computer system GEOPAK-2. The system can solve three classes of problems providing construction of a producing formation geological model according to the type of a filtration model used: a detailed geological correlation of well profiles; an estimation of the object geological structure complexity parameters; geometrization of pools and differentiated calculation of reserves.The first of them is ba sic for solving the others.The re sults of solving the second one are used in oil recovery estima tion procedures based on one—di mensional statistical models of filtration.The solution of the third-class problems is necessary when using two- and three-dimensional determined models of filtration.
