The article “Methodological approach to construction of hydrocarbon deposits geological models in the middle jurassic deposits of the Western Siberia in conditions of abnormally high reservoir pressures”, was published in the scientific and technical journal “Geology, geophysics and exploration of oil and gas fields”. Prepared by INGEOSERVICE LLC, TIPGG W-Sb RAS, TIU and Gazprom Nedra LLC employees. Authors: Smirnov O.A., Borodkin V.N., Lukashov A.V., Plavnik A.G., Trusov K.A. and Galinski K. A.
The article, based on the analysis of geological-geophysical data in the section of the Middle Jurassic deposits, characterized by abnormally high reservoir pressures (AHRP), considers thermobaric conditions and a model of the hydrocarbon deposits phase state, the problem of identifying reservoirs (FES) according to the complex of field geophysical studies and core material, regularities FES changes with depth and connection with AHRP. The relationship between productivity and AHRP was also noted. When identifying a hydrocarbons deposit boundary in a reservoir under high pressure conditions, an important component of research is building of an open porosity reservoir map and the reservoir pressure anomaly coefficient.
