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 a marker depth coordinate for a well W for construction of a geological model of a mineral deposit, computerized system comprising:

• one or a plurality of processors;
• input/output moduli (I/O);
• a computer-readable medium, containing a program code, which, when executed, induces the processor or processors to implement the steps of:
• 1) determining a reference group of wells;
• 2) determining wells W located within the given neighborhood of the reference well group wherein the neighborhood does not exceed a distance R from any well in the reference group;
• 3) determining the correlation function C(z)and choosing for each well W found in a preceding step an appropriate well of the reference group with the maximum correlation coefficient and finding a point zmax corresponding to the reference group in well W;
• 4) checking the well W with the use of tests, and, if the check is successful, the choice of the well is assumed approved, and the depth corresponding to the maximum value of correlation zmax is taken to be the depth of the marker in well W;
• 5) adding the obtained well W to the reference well group;
• and
• 6) reiterating all steps of the method until no well W is found at the steps 1), 2), or 3).

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 method for determining a position of a coordinate of marker depth in well W for construction of a geological model of a mineral deposit, the method comprising:

• 1) determining a reference group of wells;
• 2) determining wells W lying within a specified neighborhood of the reference group of wells where the neighborhood does not exceed the value of distance R from any well of the reference group;
• 3) determining a correlation function C(z), and choosing for each well W identified at the previous stage a well from the reference group with the maximal correlation coefficient and an appropriate point zmax in well W;
• 4) testing the well W, and, if the tests are successful, the choice of the well is approved and the depth zmax corresponding to the maximal correlation is taken as the marker depth at well W;
• 5) adding the well W thus found to the reference well group;
• and
• 6) reiterating all steps of the method until no well W is found at step 1) or steps 2) or 3).
