The problem of the relationship of oil and gas deposits inter-relation with the regional faults of the Earth’s crust remains relevant, popular by professional community and requires further investigation. A favorable ground for this is the shelf of Vietnam with the adjacent Indochina peninsular, which together are considered as tectonically active young epi-Mesozoic platform, where the processes of oil and gas generation and accumulation pass rather intensively nowadays. The Russian-Vietnamese joint operating company (JOC "Vietgazprom") conducted a significant amount of seismic surveys, drilled wells with a good core recovery. The article is devoted to the study of the results of these researches and the development of recommendations on exploration work.

 

Key words: shear dislocation; faults of the Earth’s crust; distribution of CO2; oil and gas accumulation.

The article presents the analysis of oils’ physical and chemical properties as a part of the Middle Jurassic (Yu2 layer), the Upper Jurassic (Yu1 layer) and the Lower Cretaceous coastal shallow water (layers of B group) and isochronous relatively deep clinoform formations of Achimov stratum (layers of Ach group). The impact of the hydrocarbon systems’ phase zoning on their properties is underlined; the latter one (Achimov stratum), along with the other factors, is subjected to the effect of paleotectonic criteria.

The article presents the results of lithological-petrographic and biostratigraphic studies of the Upper Devonian-Tournaisian productive stratum, located in the north-east of Perm region, based on the data of new exploration wells drilling. The boundary of the Devonian and Carboniferous systems is defined in accordance with the presence of a break in sedimentation and change of reef complex deposits of Famennian stage for shallow shelf formations of Tournaisian stage. According to biostratigraphic studies the border starts with a sharp decline of paraturammine fauna and appearance of multi-foraminifera in the cross-section.

The following foraminifera predominate among the Upper Devonian ones: Parathurammina radiate Antropov, P. breviradiosa Reitl. and P. dagmarae Sul., as well as the following species such as Bisphaera sp., Neotuberitina maljavkini Mikh are also met. Multi-chamber foraminifera of the Tournaisian stage are mostly represented by the species of Tournayellidae family. The data analysis of petrophysical studies witnessed the fact that in the context of generally low values of reservoir properties there noticed higher values of the established stratigraphic level. The article proves the feasibility of biostratigraphic studies.

 

Key words: the Upper Devonian-Tournaisian carbonate sediments; reef stratum; Bereznikovsky paleoplateau; exploration wells; petrographic researches; foraminifera; boundary; reservoir properties; biostratigraphic studies.

The paper presents the study of the Upper Cretaceous section interval. Using a set of facial and stratigraphic studies, based on the data reinterpretation of areal and volumetric seismic surveys, with account of drilling data there detailed the geological structure of the Turonian age promising deposits of the Upper Cretaceous deposits in the territory of Bolshekhetsky project and adjacent areas (Bolshekhetsky depression and Messoyakhsky mega-swell). The traps are mapped and the resources evaluated.

At present, in the old oil and gas producing regions, the procedure of expert assessments of oil and gas potential becomes complicated. The authors of the article have acquired considerable experience in conducting probabilistic estimates of petroleum potential of areas with varying degrees of knowledge and geological structure. The article will determine a set of informative geochemical criteria for assessing generational and accumulation processes and build probabilistic model of oil and gas potential.

 

Key words: Domanic deposits; geo-chemical characteristics of rocks; epigenetic bitumoids; informative indicators; oil-bearing criterion; probabilistic models; forecast oil and gas potential.

The research is devoted to the conditions of occurrence and geological-geochemical characteristics of oils of oil and gas complexes (OGC) of the Volga-Ural oil- and gas-bearing province (VU OGP) in order to fix their genetic relationships with Domanic deposits, which in the east of the East European platform, according to many experts’ opinion, are nearly the only ones highly hydrocarbon Paleozoic formations. When generalizing a lot of information the results of the researches both carried out by the authors (analytical as well) and those from files and literary sources, including reference books were used. The article discusses some specific features of the geological structure and oil potential of producing horizons, geochemical varieties of Paleozoic oils, probable paths of oil migration, time period of deposits formations, which together allowed identifying the role of Domanic deposits in the resource hydrocarbon potential of the Ural-Volga region.

 

Key words: oil; Domanic deposits; geochemical indicators; trace elements; conditions of deposits formation.

The data presented in some recent papers indicate significant divergence in numerical solutions obtained, using different commercial simulation software, and on regular and irregular grids with different cell sizes. The present paper analyzes the causes of such divergence associated both with general features of numerical simulation algorithms for single- and multiphase flow processes in porous media and peculiarities of their implementation in the simulation software. The problem of solution convergence is addressed for reducing grid cells and time step sizes. Special consideration is given to simulation of fluid inflow to wells of different types, principles of grid construction and refinement, necessity of a reservoir parameters and fluid upscaling/downscaling when changing to coarser or finer grids and to the influence of numerical algorithms tuning. Practical suggestions are presented for achievement of credible results using commercial simulation software.

 

Key words: flow simulation; numerical solution; simulator; grid refinement; convergence; well modeling; inflow relation; upscaling; downscaling; single-phase flow; multiphase flow.

According to the proposed scientific assessment, covering 24 shale basins, the Russian Federation has the largest, after the Persian Gulf region, technically recoverable resources of "shale" hydrocarbons (60 billion tons of oil and 50 trillion m3 of gas). Among the considered shale basins the particular interest, in terms of large-scale industrial development, is attracted by those ones associated with the zones of the earth's crust stretching. In Sarpinskiy basin (south-western part of Central Rift zone of the Earth's crust stretching in the Caspian Basin, with the depth of the crystalline basement to 23…24 km), enormous hydrocarbon resources are expected in the thick shale strata of Early Carboniferous age at technically accessible depth of 8…9 km. In the Nelkan–Sette-Daban rift-thrust zone (between the Aldan shield and the Okhotsk massif with the depth of the crystalline basement to 18 km) large commercial hydrocarbon resources are expected in connection with the source shale strata of middle Riphean (malginskaya formation) and lower-middle Cambrian (inikanskaya formation) age.

 

Key words: shale hydrocarbons; source formations; scientific assessment of resources.
