pdf  The role of fracture in the formation of capacitive-filtration space of complex reservoirs
The main provisions of the theory of fracture, developed in VNIGRI, which are of help in forecast of and search for fractured reservoirs have been presented in the article. The express method of total (background) fracturing and reservoir rocks potential estimation enabling us to make preliminary lithological and rocks texture evaluation of capacitive-filtration potential of the sequence has been proposed. The necessity for an integrated approach in the study and forecast of complex fractured reservoirs has been emphasized.
Key words: fracture, complex oil and gas reservoirs, reservoir potential, genetic classification of fractures, micro-fractures.

pdf  Lithology and reservoir forecast of kolganskaya formation of Vakhitovsky field, Kichkasskaya area, southern Orenburg region
Sand bodies have been identified and delineated in the Upper Devonian carbonate sediments within the Kichkasskaya area of Colgan-Borisov Trough (southern Orenburg region) on the basis of lithological, petrographic and petrophysical studies of kolganskaya formation. Maps of facies and a map of prospective reservoir rocks development have been drawn; prospective areas for hydrocarbon exploration have been identified on the poorly explored areas.
Key words: Devonian, limestone, sandstone reservoir properties, facies, clinoforms, the forecast of lithologic traps.

pdf  Lithological aspects of the carbonatereservoir rocks study
The main types of carbonate rocks and the conditions of their formation have been considered. The scheme of calc-dolomite rocks classification developed in VNIGRI has been presented. The factors and processes of sedimentation, diagenesis, catagenesis have been discussed as well as their role in the creation of the pore space structure determining rock-and-fluid properties of rocks considering the region’s geotectonic conditions.
Key words: carbonate rocks classification, structure of pore space, sedimentogenesis, diagenesis, catagenesis.

pdf  On the petrography of clay-carbonate rocks of Chokrak and Caragan, Grozny-Dagestan region
The petrographic characteristics of clay-carbonate rocks of the Middle Miocene of the Grozny-Dagestan region are presented. On the basis of comprehensive research the variety of clay-carbonate rocks of Chokrak and Caragan is established. The physical and chemical conditions for the formation of clay-carbonate rocks of Chokrak and Caragan in the region are described.
The article is reprinted due to the urgency of oil industry renewal in the Northern Caucasus, especially in Dagestan and the Grozny district.

Key words: petrographic and mineralogical studies, clay-carbonate rocks, composition of carbonate rocks, the Middle Miocene, the Grozny-Dagestan region.

pdf  Low-permeability reservoirs of oil and gas provinces of Russia and the CIS
Statistical analysis of porosity distribution in productive deposits of sedimentary cover of different oil and gas provinces of Russia and the CIS has been presented in the article. The essential role of low-permeability rocks (especially carbonate ones) in oil and gas potential of individual provinces (from 18 to 21% of hydrocarbon deposits in low-permeability reservoirs) has been highlighted and their association with specific stratigraphic horizons as well as the increase in the share of low-permeability reservoirs with the increase in the depth have been analyzed. The key criteria for low-permeability reservoir forecast has been formulated, most important being availability of reliable cover and enhanced fracture to support hydrocarbon filtration from pore space of matrix into the well.
Key words: carbonate reservoirs, low-permeability reservoirs, fracture, oil and gas provinces.
