Geologic structure and petroleum potential of field «Ayrantakyr»


Deposit «Ayrantakyr» is one of the most attractive fields of Southern Mangyshlak with its exploration maturity and structure. Starting with 50s of the last century complex geological exploration, laboratory petrophysical, geochemical and palynological studies related to its petroleum potential involving different entities were held within Ayrantakyr uplifts, and the problems concerning the formation of hydrocarbons both along the deposit, in particular, and over the region in general were discussed. Earlier laboratory studies of rocks’ reservoir properties were limited to the determination of lithology, open porosity, permeability and mineralogical density, taking into consideration the structural features of collectors. The article gives a brief description of the geological structure, lithologic and physical characterization of reservoir rocks and discusses the formation of hydrocarbons within the named field.

Evaluation of hydrocarbon bearing prospects in Cretaceous sediments of Absheron archipelago with thermobaric indicators


To understand the processes of hydrocarbon formation and accumulation, it is very important to determine the geothermal conditions of the region, which are the main criteria of oil-and-gasbearing capacity. To study the temperature and pressure conditions of the Cretaceous complex, the calculation has been provided which allowed forecasting temperature and pressure up to 6 km depth. Surfers software package allowed to build geothermal maps. Map on a section of 5000 m shows that temperature and geothermal gradient at the same depth are gradually decreased in the dipping direction of anticline zones. One negative and two positive anomalies have been identified on the depth map at 100 °C isotherm. The positive anomaly shows depth with high temperature zone of oil and gas complexes. The negative anomaly shows cooling effect of temperature to hydrocarbon phase state. Thus organic substances in Cretaceous sediments, in accordance with heating model are within MK1-2 range.

Study on hydraulic pulse cavitating jet drilling in unconventional natural gas wells


To improve the rate of penetration (ROP) in unconventional natural gas drilling and shorten the drilling cycle, hydraulic pulse cavitating jet generator (HPCJG) is designed which couples the advantages of pulsed jet and cavitating jet on the basis of the analysis of the jet-modulating mechanism. When drilling fluid flows through the tool, the fluid will be modulated to the pulsed and cavitating jet by application of the impellers and by entering into the self-resonant chamber. Thus, pulsed cavitating jet is formed at the outlet of the bit nozzle. Because of jet pulsation, cavitating erosion, and local negative-pressure effect, the cleaning efficiency of wellbore cuttings and the ROP will be enhanced. Several well-times of field tests with HPCJG were conducted in Xuanye-1 well in shale gas well and Zhi-4 well in coal bed gas well, and the ROP comparison between field tests intervals with HPCJG and that of adjacent intervals of the same well or adjacent wells without HPCJG were carried out. The tests results show that the ROP of Xuanye-1 well in 2 two different wellbore sizes are 2.73 m/h and 1.74 m/h respectively. The average ROP of field tests interval were enhanced by approximately 58.2% and 18.1% compared with the adjacent intervals. The ROP of Zhi-4 well is 1.74 m/h, and the ROP of field tests were enhanced by approximately 21.6% compared with the adjacent Zhi-1 well and 187.7% compared with the adjacent Zhi-2 well. The hydraulic pulse cavitating jet drilling technology can remarkably improve the ROP of shale gas and coal bed gas drilling and reduce the drilling costs. Hydraulic pulse cavitating jet drilling technique can afford an effective approach to improve ROP in unconventional natural gas resources.

Keywords: hydraulic pulse, cavitating jet, unconventional natural gas, rate of penetration.

Studying of features of processes of formation and mechano-chemical processing synthetic hydrates of natural gas


Presented results of the research allows to expand opportunities of gases properties to interact with water on the hydrophilic steel and hydrophobic polymer contact surfaces and form hydrates with different specific gas content and morphology. Based on the experimental study of the natural gas hydrates formation and decomposition processes the composition and physical and chemical properties of the synthesized clathrate compounds were determined. It was shown the practical capability of the natural gas hydrates mechano-chemical treatment.

Hydrate formation at development of the Otradninsky gas-condensate field


Results of computational experiment on definition of possibility of hydrate formation both in bot-tomhole area and in a gas well trunk are presented on the example of gas extraction from the Otradninsky field. It is received that formation of hydrates in wells, even at low reservoir temperatures and a powerful layer of permafrost, occupies rather wide interval of time allowing quickly to prevent creation of emergencies in systems of gas supply.

The determination of the reservoir-drive mechanism of deep gas condensate deposits


The purpose of this study is to develop methodology for determination of the main source of reservoir energy by the well test analysis, i.e., the reservoir-drive mechanism of gas-condensate reservoirs. To this end, preliminary calculations have been carried out that model development of gas-condensate reservoirs with different reservoir and technological conditions. The cases considered have been analyzed for deformable and non-deformable reservoirs. The analysis of the calculation results allows for establishment of patterns of changes in pore volume of the productive formation during development. has been found that there is a strict relationship between the pattern of pore volume changes and the reservoir pressure and reservoir-drive mechanism. Based on the obtained results, has been developed an algorithm for determination of reservoir-drive mechanism in the early stages of development of gas-condensate reservoirs.

Subsea engineering and technology strategic development for the production of hydrocarbons on the Arctic shelf


Kara Sea is characterized by extreme climatic conditions (water area for 9 months is completely closed by heavy pack ice thickness up to 1.9 m, often inaccessible even to nuclear icebreakers, except in the waters of the high probability of passing the iceberg with underwater bases of more than 100 m). However, Kara Sea shelf has significant reserves of hydrocarbons currently open two deposits (Rusanovskoe and Leningrad) with reserves, providing annual production more than 80 billion m3 . Based on the results of work on the development of this deposit as basic and specific to the region, it will be possible to evaluate the prospects in general, rates and innovative technical solutions in conjunction with the development of the entire region. Extreme climatic conditions necessitate the waters of the development and use in prospecting and exploration of hydrocarbon deposits of unconventional technical and technological solutions, focused on the use of subsea technology, which is confirmed by the analysis of world experience of development of deposits in conditions close to those of the Kara Sea.
