Petrovskyy O. Mathematical models and information technologies of the integral interpretation of a complex of geological-geophysical data (based on the problems of oil and gas exploration)

The following dissertation is to fulfil the requirements of a scientific degree of Doctor of Science Physics and Mathematics science in specialization 04.00.22 - geophysics. S.I.Subbotin institute of geophysics, National Academy of Science of Ukraine, Kyiv, 2006. This dissertation is dedicated to the development of theoretical, informational and technological basics/fundamentals of the improvement of effectiveness of oil and gas exploration procedures/works. Concepts of integral geological-geophysical model and interpretation of the complex of geological-geophysical data, inclusive of passive and active models, a concept of mathematical model of geological and physical-geological cross-sections as well as mathematical model of geological-geophysical and geophysical-geological modelling have been introduced. New optimality criteria for the solution of the inverse problems of geophysics have been proposed. "An automatic system of quantitative complex interpretation of geological-geophysical data GCIS" and based on it "Technology of integral interpretation of a complex of geological-geophysical data for oil and gas fields exploration" have been created. The efficiency of the developed methods, algorithms and technologies application is illustrated by the solution of the actual oil and gas exploration problems within different regions of Ukraine and Russia. Keywords: geological cross-section, mathematical model, informational model, inverse problem, optimality criterion, integral interpretation, automatic system, geophysical well survey, seismic survey, gravimetric survey.
