Abstract
The purpose of the work is to generate a methodology to substantiate the limit values of parameters that determine the technological mode of operation for production gas wells. The basis for this is the data of laboratory geomechanical and filtration core studies and the results of mathematical modeling. Determination of filtration-capacitance and strength characteristics of weakly cemented (weakly consolidated) cores of Cenomanian and Turonian ages was carried out under reservoir conditions (in terms of baric parameters). The research was aimed at identifying the limitations, the violation of which leads to the destruction of the reservoir. A modification of the methodology for determining the marginal depression based on laboratory core studies and mathematical modeling using the Coulomb-Mohr destruction criterion is proposed. Keywords: gas wells; pressure; depression; core; stress; formation; destruction.
