[en] The idea is that petroleum deposits decrease during the second part of their life and the half of all discovered petroleum has been consumed, so the truth moment approaches. For the majority of the world the peak of the half life is around 2000. Then the petroleum price should be increase because of shortage and going on increasing

[en] The most accessible petroleum resources have already been consumed. To supply the future oil needs it is now necessary to exploit deep offshore or exotic hydrocarbon resources, like arctic fields, ultra-heavy crudes and gas hydrates. The exploitation of these resources represents a technical, economical and environmental challenge, but the profitability criterion remains the determining factor prior to any new project start-up.

[en] Oil and natural gas potential of the Gulf Arab Countries is substantial. The proven oil reserves of these countries constitute 55% of total world proven oil reserves. The Gulf Arab Countries possess 576 billion barrels of proven crude oil reserves, as compared to total world proven oil reserves of around 1047. Natural gas resources are also plentiful in the Gulf Arab Countries. Proven natural gas reserves were estimated at around 26 trillion cubic metres, at the beginning of 1997. This figure represents around 17% of total world proven natural gas reserves of around 153 trillion cubic metres

[en] The issue of assessing the radiation-chemical pollution of oil fields of the Absheron Peninsula is considered on the example of the ''Bibiheybet'' Oil and Gas Production Department (OGPD) territory polluted during oil production. For this purpose, radiation mapping of this territory was carried out, for which factual data obtained by remote sensing and field instrumental studies of the content of individual radionuclides in soils were collected. In radiation mapping the radiation situation is characterized by the compilation of the corresponding contours. The most widely used maps of radiation pollution are created by using modern software that contains the total quantity of radionuclides. High values of isolines characterize the severity of the ecological situation. Modern geo information support is required to solve ecological problems, which allows for responding quickly to any changes in the environment. For the data array throughout Absheron, the background radiation data were taken into account in the fields, in the contaminated areas, and also in areas where the increased background radiation is due to natural factors (quarries, mud volcanoes).

[en] This paper presents a mixed integer programming model for optimal development of an oil field under uncertain future oil prices. Based on a two-dimensional reservoir description, the model suggests decisions concerning both design and operation, and the objective is to maximise the expected net present value of the oil field. A finite set of oil price scenarios with associated probabilities is given, and the scenario and policy aggregation technique developed by Rockafellar and Wets is used for solving the problem. This technique is developed for the case of mixed integer problems. This is done by utilizing the interaction between the continuous (production) and integer (design) variables. We present numerical experiments and conclude that scenario aggregation may be a suitable technique also for mixed integer problems. (author)

[en] The East Zhetybai automatized system of database is esteemed in operation. The sectional system is intended for automation of information processing, and also for automation of deriving of the plot and tabulated information indispensable for analysis of a field. The system also yields calculated routines on an improvement of geological and physical properties. (author)

[en] A review of the acute and chronic effects of produced formation water (PFW), drilling fluids (muds) including oil-based cutting muds, water-based cutting muds, ester-based cutting muds and chemical additives, and crude oils associated with offshore oil and gas production was undertaken in relation to both temperate and tropical marine ecological processes. The main environmental effects are summarized, often in tabular form. Generally, the temporal and spatial scales of these studies, along with the large levels of inherent variation in natural environments, have precluded our ability to predict the potential long-term environmental impacts of the offshore oil and gas production industry. A series of critical questions regarding the environmental effects of the offshore oil and gas production industry that still remain unanswered are provided for future consideration. (author)

[en] The remarkable progress made during 1998-1999 by Precision Drilling Corporation, a Canadian oilfield service company, despite the free-fall like conditions that characterized the petroleum industry during that period, is described. The company has invested over $150 million early in 1998 to acquire Computalog Ltd and Underbalanced Drilling Systems. Both these acquisitions paid off handsomely; the company's stock jumped 150 per cent within six months, it owns 214 drilling rigs and boast a 37 per cent share of the market. With 5,000 employees, Precision Drilling is the largest publicly traded service company in Canada, and a worthy rival to the multinational giants in the field. The company had developed a particular expertise in slant drilling, and in the process reduced the cost of drilling this type of well from $ 250,000 to $ 60,000. Diversification into contract drilling services, oilfield specialty services and rental and production services, especially with the acquisition of Computalog, also contributed significantly to the Company's success. The acquisition of Computalog brought with it an array of leading-edge electromagnetic measurement tools for drilling. Taking these technologies world-wide is the next aspiration of this very successful Canadian company. As an indication of the seriousness of the company, Precision Drilling is already well ensconced in Venezuela, has contracts in Oman, Argentina and Brazil, and has plans to work in the Middle East
