[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] Nigeria produces almost two million barrels of oil a day from its oil fields in the Niger Delta area. Most of the oil comes from reservoirs containing gas, which is produced with the oil. This associated gas is separated from the oil at flow stations and more than 95 per cent of it is flared-currently a total of some two billion standard cubic feet per day (scf/d), which is estimated to be about a quarter of the gas the world flares and vents. The energy available from Nigeria's flared gas is prodigious, equivalent to one quarter of France's gas requirements. The company recognises that flaring wastes a valuable resource and is environmentally damaging. It aims to stop necessary flaring as soon as possible through a series of projects to harness or conserve this gas. Several gas gathering and conservation projects are already underway in response to emerging markets while other plans await new markets. The company is committed to reduce gas flaring as soon as is feasible to the minimum needed to maintain safe operations. But why are solutions being found only now? why has Nigeria been flaring gas for so long? These question lie at the crux of the debate about Nigeria and gas flaring and the answers, which continue to have a major impact on associated gas development today, are rooted in history, economics and geography

[en] This application for approval to develop the Terra Nova Field off the coast Newfoundland was prepared by Petro-Canada on behalf of and with the cooperation of it co-proponents of the project, i.e. Mobil Oil Canada, Husky Oil, Murphy Oil and Mosbacher Operating Limited. The Development Plan, Part 1, contains the details of the engineering, reservoir, and economic plans for the Terra Nova Field. Among the many topics discussed are the following: a description of the geology, geophysics and petrophysics of the area, details of drilling and completion plans, production and transport systems, construction and installation, operations and maintenance, safety plans, decommissioning and abandonment plans, and development and operating cost data. 115 refs., 1 glossary

[en] Supplement B to the Terra Nova Development Application provides a description of the floating production storage and offloading (FPSO) vessel system selected for the development, a summary of the reasons for selecting the system, and the impact of this selection on the Development Plan, the Benefits Plan, the Environmental Impact Statement and the Socio-Economic Impact Statement. There is also a description of the contractor alliance approach to be used in the Terra Nova Development. Refs., tabs., figs

[en] This document provides responses to the questions addressed to the proponents of the Terra Nova Development by the Environmental Assessment Panel. The questions and the responses concern hiring practices, labour relations, environmental and wildlife protection, impacts to the Grand Banks fishing industry, operating practices and the effects on offshore installations should extreme conditions of ice, weather, sea and wind occur simultaneously. References cited in response to individual questions are included following each response. Tabs., figs

[en] Through additional exploration, the spacial distribution rules of the ore bodies at Gaoxi uranium deposit were found out. Taking into account the characteristics of ore bodies with complex shapes and changeable occurrences, different mining method were selected, that is, upward horizontal cut-and-dry filling method, short-hole shrinkage stoping method and benching long-hole caving method. The application of the three methods to this uranium deposit was introduced, their application effects were evaluacted, and the measures of improvement were put forward aimed at existing problems.

[en] The technical characteristics and application conditions of multi slicing-and-caving method are introduced. Based on application of mining practice in a uranium deposit, the advantages, disadvantages,and main technical and economic indicators of multi slicing-and-caving method are analyzed. Some corresponding improvement measures are suggested simultaneously. Furthermore, the technical feasibility, safe reliability and economic rationality of the improved mining method are illustrated consequently. (authors)

[en] India has an ambitious energy programme of generating 60 GWe nuclear power by 2032 and 655 GWe by 2050, to bridge the gap between energy generation and its demand. Geological and seismotectonic characterization of Bundelkhand massif has been carried out, as per Atomic Energy Regulatory Board guidelines, for its suitability for installation of nuclear establishments. Bundelkhand massif occupies a large area measuring nearly 26,000 km², and is under seismic zone – II, where no discernible seismicity has been recorded. The preliminary geological studies indicate absence of active faults. Studies of geological/geotechnical hazards, like slope stability, subsidence or uplift, surface collapse and soil liquefaction potential indicate favourable site characteristics. Rajghat and Matatila dams, with a gross storage capacity of 2172 MCM and 1132.7 MCM, respectively, are located on the downstream side of Betwa river in the study area and have potential to be considered for the cooling water requirements. Besides, the integrated study favours suitability of site in the vicinity of the Rajghat and Matatila dams within the Bundelkhand massif for the establishment of nuclear installations. (author)

[en] The Socio-Economic Impact Statement contained in this volume is part of the overall application for approval of the the development of the Terra Nova Field, prepared and submitted by Petro-Canada on behalf and in cooperation with its co-proponents. It describes the baseline conditions for, and the effects of the Terra Nova Development on the fishery, industry, employment, demography, housing, social infrastructure and services, public infrastructure, and municipal government. A description of the scope of the assessment and the methodology employed is complemented by a 10-page glossary and a 36-item bibliography

[en] Energy is essential to the functioning of society, and oil is the single largest commercial energy source. Some analysts have concluded that the peak in oil production is soon about to happen on the global scale, while others disagree. Such incompatible views can persist because the issue of 'peak oil' cuts through the established scientific disciplines. The question is: what characterizes the modeling approaches that are available today, and how can they be further developed to improve a trans-disciplinary understanding of oil depletion? The objective of this thesis is to present long-term scenarios of oil production (Paper I) using a resource-constrained model; and an agent-based model of the oil exploration process (Paper II). It is also an objective to assess the strengths, limitations, and future development potentials of resource-constrained modeling, analytical economic modeling, and agent-based modeling. Resource-constrained models are only suitable when the time frame is measured in decades, but they can give a rough indication of which production scenarios are reasonable given the size of the resource. However, the models are comprehensible, transparent and the only feasible long-term forecasting tools at present. It is certainly possible to distinguish between reasonable scenarios, based on historically observed parameter values, and unreasonable scenarios with parameter values obtained through flawed analogy. The economic subfield of optimal depletion theory is founded on the notion of rational economic agents, and there is a causal relation between decisions made at the micro-level and the macro-result. In terms of future improvements, however, the analytical form considerably restricts the versatility of the approach. Agent-based modeling makes it feasible to combine economically motivated agents with a physical environment. An example relating to oil exploration is given in Paper II, where it is shown that the exploratory activities of individual agents can yield a U-shaped exploration cost path. Agent-based modeling appears to have significant potential for future development, but it is still unclear whether it will be the most useful in policy evaluation or more generalized systems research
