The current hard-to-recover oil reserves in Russia stand for more than 60% of total recoverable oil resources. These kind of reservoirs with acceptable technical and economic indicators are extracted only by applying physicochemical recovery techniques. Thus, an important relevance is given to selection of most effective EOR technology, which is directed to decrease the residual oil saturation in rock formations. Various chemical reagents including composites based on water-soluble polymers are injected both in Ru...

The most appropriate way to increase grip of bitumen with mineral materials is the use of adhesive additives which are slowing down the process of aging of bitumen due to oxidation and increasing durability of pavement. Adhesive properties of bitumen are important characteristics, as they are having a huge impact on operational properties of composite materials, such as asphalt mixtures. To understand the chemical behavior of the binder components interaction and improve adhesion to mineral components of asphalt c...

Extra-heavy oil is considered as one of alternative energy sources mainly because of reserve potentials, rich in organic compounds and rare transition metals like V and Ni. Extraction from this hydrocarbon resource has always been a challenge due to high oil viscosity and as a result low mobility within porous media. Conventionally the production from extra-heavy oil reservoirs is achieved by thermal methods such as SAGD, CSS, Insitu combustion, etc. However, these techniques do not consider the post productionsпї...

Within the crystalline basement of the Tatar arch of the East-Russian plate, specific zones are distinguished, which can be attributed to unconventional reservoir zones. According to previous studies, different types of genesis are generated: decompressed zones of destruction of great depths, weathering crusts at the boundary of the sedimentary cover and crystalline basement, fractured permeable zones subjected to later hydrothermal processes, etc. Formation of different types of reservoir zones is associated with...
