FIELD: physics, computer engineering.
SUBSTANCE: invention relates to a method, a device and a computer-readable data medium used when constructing a geologic model of an oil or other deposit. The invention enables, for markers selected as the initial solution, to calculate marker depths at each well which provide the best overall correlation. The method includes determining, for each marker which is part of a set, a composite function which is the sum of correlation coefficients of a system of well logging techniques for pairs of wells located no more than a given distance from each other. Partial derivatives are calculated for said composite function and the obtained vector is smoothed and used to find a greater value of the composite function at a certain section along said vector. If a greater value is not found, the last position of the marker is considered the solution, otherwise the solution point is smoothed and the process is repeated. The marker depths are sorted at each algorithm iteration.
EFFECT: improved accuracy of calculation of parameters used to construct a geological model of the location of oil or other deposits.
