The peculiarity of this work is in the planning of the pilot works and the development of low-permeability fractured gas reservoir by horizontal wells with multi-stage fracturing considering natural fractures impact which taken into account on the basis of integrated approach with petrophysical, geological, geomechanical and dynamic modelling.

The article presents the results of multivariant calculations of hydraulic fracturing design dynamic modelling with and without natural fractures depending on the well placement, length and orientation of the horizontal well, geometry of hydraulic fracture, as well as possible effects that occur during the operation of the wells.

Technological constraints (geomechanics input) were taken into account as a basis for evaluation of horizontal well trajectories with multi-stage fracturing for the pilot works and recommended for implementation during the subsequent fullfield development for target gas reservoir, as well as replication of the experience for the similar assets of the Company.
