The work is devoted to the development of geochemical criteria for determining the nature of saturation for deep-adsorbed gases in the core. As the object of investigation used the core material selected in the fields in the Nadym-Pyrskoy oil and gas field. In each sample, 72 components were determined, namely, hydrocarbons of different material groups: normal, branched, polycyclic, and aromatic compounds from butane to dodecane. With respect to the quantitative distribution and correlation among the components, qualitative geochemical indicators of sediment productivity have been developed. The saturation character established by the criteria of deep-adsorbed gases was confirmed by the test results. In this regard, this research method significantly increases the effectiveness of diagnostics of prospective deposits, the application of which is relevant in the territory of the West Siberian oil and gas basin, especially when studying deep-submerged deposits of complex geological structure.

The article is devoted to the hydrogeochemical conditions of the Mesozoic hydrogeological basin within the Russkoye oil and gas field. The text gives valuable information on the natural conditions, geological structure, geotemperature regime of the bowels of the Earth and the composition of groundwater of the Aptian-Albian-Cenomanian, Neocomian, and Jurassic hydrogeological complexes. The change in the composition of groundwater in the section of the AptianAlbian-Cenomanian complex has been revealed. Vertical inversion zoning that traces the underlying the Neocomian complex is established. We describe the main features of the regional distribution of reservoir pressures. Hydrodynamic schemes of the Aptian-Albian-Cenomanian, Neocomian, and Jurassic hydrogeological complexes are given in the article. These schemes show that the Russkoye gas and oil field is located in the zone of low reservoir pressures. The above vertical inversion zoning and low reservoir pressures are associated with the location of the field within the elisional hydrodynamic water pressure system of the Yamal-Gydan lineaments. The data of the block-fault model of the considered field were used in the course of the study. The block-fault structure predetermined the migration of hydrocarbons and the formation of tectonically screened deposits.

The findings of the geological and geophysical researches reveal the high prospects of Krukenychi Depression in terms of new deposits discovery. Notably, some productive reservoir rocks have been indentified within the Neogene formations of Tyniv-Hrushiv Oil and Gas Field. The major gas capacity is associated with the lower Dashava deposits; that is supported by considerable well rates which were apparent within previously discovered fields. According to the readings of the geophysical well logging, the correlation pattern of prospective strata distribution has been introduced; as a followup, it has been determined what the fluid content is within the lower Dashava age. Consequently, just over the gas-bearing reservoir rocks, the waterbearing strata have been located. The geological structure of the lower Dashava age is featured by the two-meter unit of claystones and siltstones which separate the water-bearing strata from the productive ones. The very feature of the geological structure causes the encroachment of productive horizons; that is proved by the well testing results. The more thorough researches help to define the key factors which influence the distribution of the sand material through the section of the Sarmatian age. Furthermore, it is possible to set up a water and gas ratio within the productive strata.

Since commencing operatorship in the Amadeus Basin in June 1980, the Amadeus Joint Venture has acquired 3000 km of multifold seismic data and reprocessed 2500 km of existing single fold and multifold data. These data, integrated with geological, Landsat, gravity and airphoto information, led to the drilling of eight exploration wells, which resulted in two gas discoveries (in the Dingo 1 and West Walker 1 wells) and numerous additional oil and gas shows in the remaining wells.Interpretation of these multi-discipline data has enabled a number of significant structural trends and styles in the Amadeus Basin to be defined. Individual prospects within some of the major structural trends have now been tested by the drill. This paper describes the nature of these structural trends and illustrates geologically and geophysically typical examples of drilled prospects existing within these trends.The primary exploration targets in the Amadeus Basin are the Ordovician Stairway and Pacoota Sandstones (confirmed by the Mereenie Oil and Gas Field, Palm Valley Gas Field, and the West Walker gas discoveries) and the Precambrian-basal Cambrian Arumbera Sandstone (confirmed by the Dingo gas discovery). Geochemical and maturation data indicate that significant additional oil and gas accumulations can be discovered in these formations.Data from Dingo 1, Mt Winter 1 and Finke 1 have again indicated that significant quantities of both oil and gas have been generated in the Late Proterozoic sediments of the Basin. An active exploration program is continuing and will endeavour to confirm these expectations.

Internationally the research of low permeability oil reservoir is a difficult point in the exploration and development of oil and gas field. This thesis, based on the research methods of low permeability reservoirs at home and abroad, summaries several major problems encountered in the process of low permeability oil exploration and development under the current technical conditions as well as the corresponding, but more effective technical measures that need to be constantly improved. And that exploration and development of low permeability of the reservoir will be the main battle field for some time in the future of oil exploration and development.
