Systems and methods for determining position of marker depth coordinates for construction of geological model of deposit

A computerized system for determining a position of marker depth coordinates in wells W of a reference group of wells at the building of a geological model of a deposit, the computerized system comprising:

• one or a plurality of processors;
• input/output moduli (I/O);
• a machine-readable data carrier (memory), containing a program code, which induces the processor or processors to implement steps comprising:
• 1) determining well W and wells located within a specified neighborhood of the well W, the neighborhood radius being R;
• 2) determining the marker depth mark {zi}, i=0, . . . , n in each well W and wells located within a specified neighborhood of the well W;
• 3) evaluating the functional C in points, for which the value of marker depth mark {zi} is available;
• 4) forming gradient vectors for the points, for which the value of marker depth mark {zi} is available;
• 5) smoothing the gradient vector by replacing each component of the gradient vector in well W by the mean value of components of gradient vector in wells in the neighborhood with radius R;
• 6) searching for a value of the functional C greater than the previously found value of the functional C within a segment of specified length starting from the marker depth mark {zi} in the direction of the gradient vector with the current value of marker depth mark {zi} assumed determined when no such value is found;
• 7) improving the obtained value of marker depth mark {zi} by searching for a larger value of marker depth {zi} within the specified step;
• 8) smoothing the gradient vector for the marker depth mark {zi} at which the functional C is maximal by replacing each component of the gradient vector in well W by the mean value of components of gradient vector in the wells in the neighborhood with radius R reduced by a specified value;
• 9) sorting the marker depth marks {zi} by depth;
• and
• 10) reiterating the steps 4)-10) of the method until a larger value of the functional C is found.

A non-transitory computer-readable medium embodying a asset of instructions, which, when executed by one or more processors, cause the one or more processors to perform a computer-implemented method for determining a position of coordinates of a marker depth in well W for building of a geological model of a deposit, the computer-implemented method comprising:

• 1) determining wells W and wells located within a specified neighborhood of the well W, the radius of the neighborhood being R;
• 2) determining the values of the mark of marker depth {zi}, i=0, . . . , n in each well W and in wells located within a specified neighborhood of the well;
• 3) evaluating the functional C in points where the value of marker depth {zi} is known;
• 4) composing gradient vectors in points where the value of marker depth {zi} is known;
• 5) smoothing the gradient vector by replacing each component of the gradient vector in the well W by the mean value of components of gradient vector in wells in the neighborhood with radius R;
• 6) searching for a value of the functional C greater than the previously found value of the functional C within a segment of specified length starting from the marker depth mark {zi} in the direction of the gradient vector with the current value of marker depth mark {zi} assumed determined if no such value is found;
• 7) improving the obtained value of marker depth mark {zi} by searching for a larger value of marker depth {zi} within the specified step;
• 8) smoothing the gradient vector for the marker depth mark {zi}, at which the functional C is maximal, by replacing each component of the gradient vector in well W by the mean value of components of the gradient vector in wells in the neighborhood with radius R reduced by a specified value;
• 9) sorting the marker depth marks {zi} by depth;
• and
• 10) reiterating the steps 4)-10) of the method until a larger value of functional C is found.
