Abstract
This article continues the series of articles devoted to the work on optimizing the system of developing collectors with low filtration properties on the example of the Erginsky license area. Measures for further cost-effective development of the site are considered: drilling horizontal wells across the direction of regional stress propagation, increasing the number of hydraulic fracturing stages, operation of wells in a gentle mode.
Materials and methods
With the use of hydrodynamic modeling, the reversal of the well drilling scheme is justified: the previously adopted development system assumed the drilling of horizontal wells along the direction of regional stress propagation. It is proposed to increase the number of hydraulic fracturing stages and the mass of the proppant for each port. The results of the implementation of pilot works on drilling and commissioning of the first “longitudinal” and “transverse” wells with a large-volume multistage hydraulic fracturing in a “gentle” operating mode are presented.
