FIELD: physics, computer engineering.

SUBSTANCE: invention relates to a method, a device and a computer-readable data medium used for building a geological model of an oil or other mineral deposit, particularly for determining correlation coefficients for a set of well-logging curves and finding the position of marker depths, for which the correlation coefficient value is maximum. The method enables, for a marker already having marks at a certain so-called reference group of wells, to calculate said marks for a well from another group. For each well W, on which the marker depth value is being searched for, wells of a reference group lying at a given distance from well W are selected, and from among them a well is selected with the highest correlation coefficient, wherein the point at which said maximum is reached is denoted as the desired mark of the marker. Verification tests are used to search for wells in which the correlation function is less than the maximum correlation coefficient, and the correlation quality coefficient is greater than the maximum correlation coefficient. The found well is added to the reference group of wells.

EFFECT: improved accuracy of calculation of parameters used to build a geological model of the location of oil or other deposits.
