Choosing a strategy for the development of hard-to-recover oil reserves based on integrated modeling

The article presents an integrated approach to the selection of most optimal option for involving in development oil reserves confined thin-layered clay-bearing reservoirs, based on modeling. Previous studies facies, geological and petrophysical reservoirs reservoir under consideration using a newly sampled core made it possible reconsider prospects production, which was previously considered unprofitable. use spectral method take into account high anisotropy properties achieve highly detailed model, basis increase initial (IGZ) by more than 50% their belonging category hard-to-recover (TRIZ) is justified. assignment deposit TRIZ apply preferential coefficient mineral extraction tax, increased economic attractiveness project. To reduce risk involvement underlying water-saturated interval, elastic-deformation rocks were carried out, geomechanical model built select parameters hydraulic fracturing (HF) operation. location production injection wells, as well hydrodynamic feasibility study systems directional (DW) horizontal wells with multi-stage (HW+MHF) out.
