[en] Method for definition of optimal bottom pressure value for exploring wells is supposed on the base of standard mathematical model. (author)

[en] Industrial petroleum and gas content of Kumkol deposit is determined. It dated to Lower Neocomian and Upper Jurassic terrigenous stage sediments. It is determined, that its lithologic characteristics are very different. That is explained by various condition of sedimentation. (author)

[en] Possibilities of geophysical research for monitoring and forecasting the ground destabilization on Karachaganak petroleum deposit caused by underground nuclear explosions are evaluated. The most informative and profound are the methods of seismic investigation, vertical seismic profiling and borehole logging. (author)

[en] More western operators are shaping upstream deals with republics of the former Soviet Union. This paper reviews some of those deals concerning exploration and development of the republic's petroleum resources

[en] Intensive exploring geological surveying works were carried out for revealing of fuel resources in South Kazakhstan. Number of complex gas deposits - Ajrakty, Amangel'dy, Kumyrly and others as well as Northern Usharly and Usharal-Kemirtobe deposits of nitrogen-helium gas are recovered. Introduction its into operation has significant importance in consequence of urgent fuel deficit in region. Basic way of guaranteed gas supply to industry and population of South Kazakhstan is connected with own hydrocarbon fields development

[en] In this article an influence of petroleum industry and especially discovery of hydrocarbon deposits with high content of hydrogen sulfide to ecological safety and environment is shown. New criteria for zoning and geological estimation are presented. For the first time a parameter of territory ecological protection is offered. (author)

[en] Sometimes a geologist becomes convinced that oil cannot occur in an area and finally says he will drink all the oil found there. When this happens, he should ask for a transfer. He has been in the area too long. Negative thinking never found a barrel of oil. This paper reports that a good geologist should critically examine and challenge the statements and theories of others in his own mind. He should follow up with positive actions based on his ideas and sell them to management. By so doing, he will be a creator of fires instead of a fire fighter. It is the creator who has the most to gain and obtains the bulk of the oil reserves

[en] The analysis of up-to-date situation in development of deposit is spent. It is shown that use the constantly working models allows to adequately describe a real condition of research objects, to reflect its geological and physical peculiarities, to take into account vast variety of the initial information with various degree of detail, to adequately describe a wide range of systems under development, boundary conditions in wells, modern technologies, to carry out the detailed all-round analysis of calculation results and choose optimum variant of development.

[en] Laboratory researches with using of alloys of energy accumulating substances are carried out with the purpose of petroleum output increase on Kumkol deposit. Factor of petroleum replacement within range from 79.5 to 82.0 % is received by use silico-barium, silico-calcium and ferro-silicium with alkali and aluminium. (author)

[en] Recent studies of African boundaries have tended to focus either on the growing number of border disputes between states or on frontier regions that are said to offer local inhabitants a wide range of economic opportunities. This article attempts to combine both approaches and to demonstrate the ambiguous nature of the Anglophone Cameroon-Nigeria border. On the one hand, the border has been subject to regular skirmishes between Cameroon and Nigeria, culminating in a protracted war over the sovereignty of the Bakassi peninsula - an area rich in oil reserves. On the other hand, it has for historical and economic reasons never constituted a real barrier to cross-border movements of labour and goods. The large Nigerian migrant community in Anglophone Cameroon, in particular, has been able to benefit from formal and informal cross-border trade for a long time. Unsurprisingly, its dominant position in the host community's commercial sector has been a continuous source of conflict. (Author)
