Abstract

Summary

On the basis of authors own experience, it was made an attempt to analyze the possibilities and modern approaches of identifying unconventional reservoirs and to give practical recommendations for assessing their prospects. The issues of practical implementation of interpretative models for determination of TOC content, clay content and porosity in the well sections with the purpose of estimation of shale gas resources are considered. The main criteria and limitations for the allocation of perspective objects in well sections are presented in order to realistically account for shale gas resources and gas of tight reservoir rocks. It is shown that the use of the most commonly used method of Q. Passey is quite effective in calculating the TOC content in terrigenous sections of the Serpukhovian of oil and gas fields of DDD. Typical values of gas saturation coefficients and range of possible porosity values inherent in tight reservoir rocks of the Serpukhovian of the of the South side of the DDC are presented and recommended by the authors.
