SYSTEM AND METHOD FOR MINIMISATION OF DRILLING MUD LOSS Russian patent published in 2013 - IPC E21B47/00 G06F19/00 

FIELD: oil and gas industry.

SUBSTANCE: system contains one or more sources providing data representing aggregated fractures in formation, processor of computer connected to one or more sources of data, at that processor of computer contains carriers containing output code of the computer consisting of the first program code for selection of variety of materials to control drill mud losses out of list of materials in compliance with data representing total number of fractures in formation and the second program code related to the first program code and purposed for determination of optimised mixture for selected materials to control drill mud losses to apply them for fractures; at that optimised mixture is based on comparison of statistical distribution for selected sizes of materials to control drill mud losses and sizes of aggregated fractures.

EFFECT: reducing loss of materials and improving operational efficiency of wells.
