FIELD: mining.
SUBSTANCE: invention relates to system and method of determining estimates of resources for the layer. Method, according to which make change of frequency of a mesh of attributes by comparing mesh of attributes and formation thickness so that, mesh of attributes contained unit of the mesh of attributes in each point of unit of formation thickness mesh, created unified mesh with multiple cells and a unit of unified mesh in each point of the unit of mesh of attributes, each unit of unified mesh has a value which is a product of formation thickness value of the unit of mesh at the point of the corresponding unit of unified mesh and value of attribute of corresponding unit of mesh of attributes with changes in frequency in the point of the corresponding unit of unified mesh replaced each inadmissible value for the corresponding unit of unified grid with one value from among of constant value and the average value, each cell of unified grid is divided into four triangle, each of four triangles comprises top in the center of the corresponding cell and two tops, which make one of four sides of the corresponding cell, create truncated prism, having volume for each combination of four triangles, by means of the computer processor, summarize volumes of all flattened prisms and the summation result reflects initial geological reserves of oil, divide the value of initial geological oil reserves into volume coefficient of the deposit, which corresponds to initial geological oil reserves in oil storage reservoir, and multiplied value of initial geological oil reserves in oil storage reservoir on the coefficient of extraction of hydrocarbons from the formation, which corresponds to reserves of extracted hydrocarbons.
EFFECT: technical result is an increasing of accuracy of determining volume of the formation.
