Abstract
At the current stage of geological exploration, hydrocarbon deposits have been discovered in complex reservoirs that are "unconventional" in nature. In particular, at the Medvezhye field, according to the interpretation of seismic surveys and the drilling of exploratory wells, a gas deposit was discovered in the Senonian deposits of the Nizhneberezovskaya suite of Upper Cretaceous deposits. The gas deposit of the NB formation of the Medvezhye field is characterised by productive reservoirs, mostly represented by mudstones and opoka-like clays. These rocks are characterized by low filtration parameters. Commercial gas inflows from secondary reservoir openings indicate the presence of fractured rock, as confirmed by core testing, mechanical logging. A comprehensive analysis of hydrodynamic studies of field parameters, such as reservoir pressure, drawdown, flow rate, allows calculating the filtration characteristics of a productive formation. The performance of fractured and mixed pore-fractured reservoirs is determined using induction diagrams and pressure recovery curves, the reservoir hydrodynamic model and methods for improving development in complex "unconventional" reservoirs are refined.
