Abstract
Due to the increasing problems of aging of the field, the annual increase in waterlogging, the decrease in the number of wells reaching the planned increase and the increase in the cost of additional measures, it is recommended to revise the number of hydraulic fracturing operations carried out in the downward direction. The article presents the selection of candidate wells of the rolling stock, when considering wells from drilling and immediately before hydraulic fracturing, recommendations for preparatory and final work are issued according to GIS conclusions. The data of the calculation of a 3-dimensional crack model, including the use of a variety of theoretical relationships to simplify computer calculations, and its results are presented. In an ordinary process, despite the large amount of data, some of their values cannot be obtained. It is suggested that the missing data should be supplemented with estimates, when selecting which you need to be extremely careful.
