Keywords: the Bazhenov formation, flow rate dynamics, horizontal wells, technological factors, geological-field analysis

Annotation:

A geological-field analysis of the dynamics of horizontal wells production flow-rates, which opened deposits of the Bazhenov formation, was carried out. The influence of completion technologies for horizontal wells with multi-stage hydraulic fracturing on the rate of production decline was studied. The influence of the number of hydraulic fracturing stages, the amount of the injected proppant, the volume of the hydraulic fracturing fluid, the number of perforation intervals on wells flow-rates dynamics was studied. The dynamics of flow rates in the wells of the Bazhenov formation and shale deposits in North America is compared. The specificity of the analyzed objects is revealed. Differences in the effectiveness of the shale technologies application in conditions of the deposits of the Bazhenov formation are shown.
