    This paper reports that foreign oil companies with concessions in northern Yemen have been drawn into a border dispute between Yemen and Saudi Arabia. At least six companies received letters from the Saudi government warning them that steps, as yet undefined, will be taken if exploration extends into disputed areas. A second territorial dispute also appears to be brewing in the region. Iran has ejected United Arab Emirates nationals from the island of Abu Musa in the Persian Gulf, which is jointly administered by Iran and Sharjah, one of the emirates. The U.A.E. government has reported the situation to the Gulf Cooperation Council, triggering a denial from Iran that anyone has been deported from the island.

    The Yemen Arab Republic ended a period of political isolation and is now pushing for social and economic development. A seven-year program announced in 1978 aims to establish and extend rural and urban electrification. A key element in this plan is the construction pf a series of diesel power stations to provide base load until larger steam plants are available in the mid-1980s.

    1986-01-01

    Thermal waters (30-61/sup 0/C) occur in springs and shallow drill-holes (max. 300 m) in several areas of the Yemen Arab Republic. Their mineral content is generally low ( < 1000-2000 ppm TDS) except for waters with high CO/sub 2/ content and those directly influenced by the evaporitic Baid formation (Tertiary) in the Western Lowlands along the Red Sea. The temperature anomalies occur in areas of Quaternary basaltic volcanism (Aden formation) and in fault zones connected with the eastern margin of the Red Sea graben. In the latter zones radiogenic heat may be contributed by Tertiary granitic intrusions.

  12. Discoveries to make North and South Yemen crude exporters

    SciTech Connect

    Vielvoye, R.

    1987-08-24

    This article reports that North and South Yemen, two of the poorest and most remote countries on the Arabian Peninsula, are on course to join the ranks of oil exporters. A major oil field at Alif in North Yemen, currently under development by Yemen Hunt Oil Co., is expected to provide first exports towards year-end. Production from North Yemen could reach 400,000 b/d in the early 1990s. In South Yemen, a Soviet oil company also has found oil. Industry sources think production will be sufficient to allow a modest level of exports. The two discoveries have brought explorationists back to a part of the Arabian Peninsula that for decades remained in the shadow of the prolific producers along the Persian Gulf coast. North Yemen attracted its first oil explorers in 1953. During the next 20 years six different groups took acreage. But activity was restricted to the more accessible coastal areas, and most groups did only preliminary geophysical work.

    1996-11-01

    The Hadhramaut province of Yemen, an area with a population of more than half a million inhabitants, is presently facing a serious water crisis. A groundwater exploration project is presently drilling 23 exploration wells widely spaced over the Masila Block, an oil exploration lease are within the province. The main target is the Cretaceous Mukalla Formation, a 300 m thick highly permeable sandstone. Field reconnaissance was integrated with satellite images; geologic, hydrogeologic, geophysical, topographic maps; and local socioeconomic and political information to choose the well locations. Studying available seismic reflection data was particularly useful for choosing drilling locations over grabens buried in wadi fill. The various pieces of information were integrated in a geographic information system (GIS). To date, eight wells have been drilled and completed. Borehole geophysical logging has played an important role in all phases of well completion. All completed boreholes have tested from 200 to over 1,000 imperial gallons per minute.

    1993-09-01

    This technical paper provides a broad analysis of forestry policy in Zimbabwe. Some two dozen contributors look at forestry as a provider of livelihood, homes and workplaces, and industrial commodities. The first section of the paper concentrates on the social and macroeconomic goals of forestry in Zimbabwe and on its place in rural agriculture. Contributors examine the issues of land tenure and the culture of common property, the practice of woodland management, and control of and participation in management and policy development. The second section focuses on the status of the forest industry in Zimbabwe and on its capacity to manage and expand existing commercial plantations. The paper explores the main issues the sector faces, including growing concentration of ownership versus the government`s objective of wider participation in the industry. They discuss the effects of trade liberalization on its competitive position, both among other agricultural sectors within Zimbabwe and with competitors outside the country. Included is a color map of Zimbabwe`s woodlands. Many forestry programs worldwide face the issues discussed in this work. It will be of interest to planners, policymakers, teachers, and students of rural development and forestry.

    The growth of oil-products demand in future years is leading the Yemen Arab Republic (Y.A.R.) to improve the distribution network for the products by constructing a pipeline system. Petroleum products are currently distributed by road tankers only between the receiving terminals and the main cities, which represent the most important consumption centers, together with new industrial plants such as cement factories, power plants, etc. The technical design and economic and financial feasibility study of the project was entrusted to Omnium Technique des Transports par Pipelines (OTP). The scope covers the setting up in the Y.A.R. of the basic equipment for the supply, storage, and land transportation of petroleum products with a view to: Meeting the national demand for the next 25 years. Providing an adequate strategic reserve of petroleum products with a total storage capacity amounting to 3 months of consumption. The only exception in the transportation of the petroleum products will involve heavy fuel oil which will continue to be transported by road tankers. This article describes the basic facilities which have to be installed before the start-up of the projected network. The project includes a marine terminal in Salif and a pipeline to Sana'a with the related storage, truck loading, and pumping facilities for white products and gas oil which will be transported by pipeline.

    1993-09-27

    Innovative electric-submersible-pump (ESP) configurations were used in the exploration phase of a Yemen oil field discovered by Canadian Occidental Petroleum Ltd. Because of subnormal reservoir pressure, CanOxy developed the field with ESPs and had to install surface components that could operate at the high, 130 F., ambient temperatures common in Yemen. The field is in a remote area that has seen very little development. The reservoirs produce a medium-to-heavy crude with a low gas/oil ratio, typically less than 20 scf/bbl. Problems faced in evaluating the field included drilling through unconsolidated sands with high flow capacity and subnormal reservoir pressure. CanOxy had to develop the technology to test the wells during the exploration phase, and intends to use new, or at least uncommon technology, for producing the wells. The paper describes testing the wells, the electric generators and variable speed drives, and the use of these pumps on production wells.

    2010-02-15

    Most countries worldwide nowadays apply Environmental Assessment (EA) as an ex ante tool to evaluate environmental impacts of policies, plans, programmes, and projects. However, the application and performance of EA differ significantly. Scientific analysis of how EA performs mainly focuses on two levels: the micro (or project) level and the macro (or system) level. Macro level analysis usually focuses on institutions for EA and the organisation of stakeholder interaction in EA. This article proposes a more comprehensive framework for analysing EA systems that combines other approaches with a capacity approach and an explicit consideration of the context in which EA systems are developed and performed. In order to illustrate the value of our framework, we apply it to the Republic of Yemen, where over the last decades many EA capacity development programmes have been executed; however, EA performance has not substantially improved. The Yemen case study illustrates that the capacity development approach allows an understanding of the historical process, the stakeholders, the knowledge component, and the material and technical aspects of EA, but perhaps more important is a systemic understanding of the outcomes: problems are not isolated, but influence and even maintain each other. In addition, by taking into account the context characteristics, our framework allows for the assessment of the feasibility of capacity development programmes that aim at improving EA system performance.

    In 1981, Yemen Hunt Oil Company (YHOC) negotiated a production-sharing agreement covering 12,600 km/sup 2/ in the northeast part of the Yemen Arab Republic. A reconnaissance seismic program of 1864 km acquired in 1982 revealed the presence of a major half graben, designated the Marib/Al Jawf basin by YHOC. A sedimentary section up to 18,000 ft thick has been recognized. Geologic field mapping identified Jurassic carbonates covered by Cretaceous sands overlying Permian glaciolacustrine sediments, Paleozoic sandstones, or Precambrian basement. The first well drilled in 1984, aimed at a possible Jurassic carbonate objective, encountered hydrocarbon-bearing sands in the Jurassic-Cretaceous transition between 5000 and 6000 ft. A successful appraisal drilling program has demonstrated satisfactory lateral reservoir continuity. Further wildcat drilling demonstrates macro-unit correlation within the eastern part of the basin. Rapid basin development apparently commenced in the late Kimmeridgian, culminating with the deposition of Tithonian evaporites. Available geochemical analysis indicates sourcing from restricted-basin sediments. Excellent traps, reservoirs, and source beds underlying the Tithonian evaporites indicate that a significant new petroliferous province is present.

The first well, Alif-1, drilled in 1984, aimed at a possible Jurassic carbonate objective, encountered hydrocarbon-bearing sands in the Jurassic-Cretaceous transition between 5000 and 6000 ft. Appraisal and development drilling followed. The Alif field is believed to contain in excess of 400 million bbl of recoverable oil. Subsequent wildcat drilling has located additional accumulations while further amplifying basin stratigraphy. Rapid basin development took place in the Late Jurassic culminating with the deposition of Tithonian salt. The evaporites provide an excellent seal for hydrocarbons apparently sourced from restricted basin shales and trapped in rapidly deposited clastics.

    A new plate reconstruction has enabled the Island of Socotra, currently located in the Gulf of Aden adjacent to the Somalian coast, to be confidently restored to its original spatial position, adjacent to the southern Omani coastline. New studies integrated with these plate reconstructions, have confirmed the presence of an untested Mesozoic graben, which trends across the Socotra platform. Fieldwork carried out in the region now enables a SE extension of the prolific Lower Cretaceous Qishn `play` (delinated in the Masilah Basin, onshore Yemen) to be postulated offshore into the Gulf of Aden. Following the award of offshore acreage adjacent to the Island of Socotra, exploration studies have confirmed the presence of the Qishn `play` both on the Island of Socotra, and offshore in the one available basin-margin control well. This work has also identified two additional plays: the Shuabia-equivalent carbonates, which are prolific producing reservoirs in central Oman; and the Permo-Triassic clastics, which may provide a new reservoir target for the region. Fieldwork has also identified Jurassic siliclastics outcropping on the Island, which may provide further reservoir potential. Ongoing multidisciplinary studies, integrating the results of a detailed geophysical interpretation with high resolution structural-stratigraphic studies, have confirmed the presence of large structures within an undrilled Mesozoic rift-basin, which will be tested during 1995.

    The objective of this study is to analyze possible long-term development options of the Zambian electric power system in the period up to 2015. The analysis involved the hydro operations studies of the Zambezi river basin and the systems planning studies for the least-cost generation expansion planning. Two well-known and widely accepted computer models were used in the analysis: PC-VALORAGUA model for the hydro operations and optimization studies and the WASP-III Plus model for the optimization of long-term system development. The WASP-III Plus model is a part of the Argonne National Laboratory's Energy and Power Evaluation Model (ENPEP). The analysis was conducted in close collaboration with the Zambia Electricity Supply Corporation (ZESCO). On the initiative from The World Bank, the sponsor of the study, ZESCO formed a team of experts that participated in the analysis and were trained in the use of computer models. Both models were transferred to ZESCO free of charge and installed on several computers in the ZESCO corporate offices in Lusaka. In September-October 1995, two members of the ZESCO National Team participated in a 4-week training course at Argonne National Laboratory near Chicago, U.S.A., focusing on the long-term system expansion planning using the WASP and VALORAGUA models. The hydropower operations studies were performed for the whole Zambezi river basin, including the full installation of the Kariba power station, and the Cahora Bassa hydro power station in Mozambique. The analysis also included possible future projects such as Itezhi-Tezhi, Kafue Gorge Lower, and Batoka Gorge power stations. As hydropower operations studies served to determine the operational characteristics of the existing and future hydro power plants, it was necessary to simulate the whole Zambezi river basin in order to take into account all interactions and mutual influences between the hydro power plants. In addition, it allowed for the optimization of reservoir management

  17. Tectonic controls on the quality and distribution of Syn- to Post-Rift reservoir sands in the Southern Red Sea, offshore Western Yemen

    SciTech Connect

    Carter, J.M.L.

    1995-08-01

    Previous geophysical and drilling results in the southern Red Sea, and the presence of numerous oil seeps, indicate that the syn- to post-rift section is prospective for oil and gas. The relatively high geothermal gradient offshore western Yemen makes intra-salt and post-salt reservoir sands the only viable exploration targets. The quality and distribution of the reservoir sands remains one of the main unknown risk factors, An improved understanding of the controls on deposition of these sands is achieved by use of LandSat data, which provide evidence of a regional tectonic framework involving NE/SW-trending oceanic transform faults which are expressed onshore as strike-slip features, in some cases representing reactivated Precambrian lineaments. These faults are thought to have played two fundamental roles in the Neogene to Recent evolution of the southern Red Sea - firstly by directing clastic input from the rising Yemen Highlands into offshore depocentres, and secondly by influencing the location of salt diapirs sourced by Upper Miocene evaporates. By considering these factors, together with the pattern of heat flow from the developing oceanic rift of the southern Red Sea, it is possible to delineate areas of offshore western Yemen where reservoir characteristics are likely to be most favourable.

    1992-10-01

    This paper reports on data concerning organic petrology and thermal maturity of Lower Karoo coal measures (Lower Permian) which are of considerable importance in determining the hydrocarbon potential of sediments in the rift-valley and half-graben complexes of the Luangwa and Zambezi valleys of eastern and southern Zambia, respectively, and in the extensive sedimentary basin developed on relatively stable Precambrian basement in western Zambia, a total area in excess of 3000 km{sup 2}. Samples from seven outcrop and subsurface localities situated in the northeast (northern Luangwa Valley), east (mid-Luangwa Valley), south (mid-Zambezi Valley), and the Western Province of Zambia were studied. The coal measures are from 9 to 280 m thick, but individual coal seams are generally less than 6 m. The coal macerals contain an average of 60% vitrinite and 9% liptinite, enough to have potential to generate hydrocarbon. A few samples contain twice this amount of liptinite. Reflected-light microscopy and the thermal alteration index of spores were used to determine the thermal maturity. The organic matter in samples studied is within the oil generation zone (thermal alteration index 2{minus} to 2+; %R{sub 0} max = 0.5-0.9). The petrological and palynological data indicate that the organic matter consists of Types II (generally approximately 25% in carbonaceous shale samples), III, and IV, indicating source rock potential. Late Karoo ( ) and post-Karoo fault blocks with differential vertical displacements may have produced structural traps suitable for oil and gas accumulation.

    A case application of data-driven estimation of evidential belief functions (EBFs) is demonstrated to prospectivity mapping in Lundazi district (eastern Zambia). Spatial data used to represent recognition criteria of prospectivity for aquamarine-bearing pegmatites include mapped granites, mapped faults/fractures, mapped shear zones, and radioelement concentration ratios derived from gridded airborne radiometric data. Data-driven estimates EBFs take into account not only (a) spatial association between an evidential map layer and target deposits but also (b) spatial relationships between classes of evidences in an evidential map layer. Data-driven estimates of EBFs can indicate which spatial data provide positive or negative evidence of prospectivity. Data-driven estimates of EBFs of only spatial data providing positive evidence of prospectivity were integrated according to Dempster's rule of combination. Map of integrated degrees of belief was used to delineate zones of relative degress of prospectivity for aquamarine-bearing pegmatites. The predictive map has at least 85% prediction rate and at least 79% success rate of delineating training and validation deposits, respectively. The results illustrate usefulness of data-driven estimation of EBFs in GIS-based predictive mapping of mineral prospectivity. The results also show usefulness of EBFs in managing uncertainties associated with evidential maps.

    Actors in the field of international development co-operation supporting the development of EIA legislation in developing countries often do not achieve the results envisaged. The performance of EIA in these countries often remains weak. One reason, we assume, is that often those actors support the establishment of overly ambitious EIA legislation that cannot achieve its objectives in the light of constraining contexts. To provide more effective support we need to better understand the enabling and constraining contextual factors that influence the development of EIA legislation and to which support actors should align itself. In this article a new analysis framework for classifying, characterizing and explaining the development of EIA legislation is described, measured in terms of ambition levels. Ambitions are defined as intentions the EIA authorities aim to fulfill, expressed in formal EIA legislation. Three country cases, Yemen, Georgia and Ghana are used to illustrate the usefulness of our framework and as a first test to refine the framework. We have formulated the following five hypotheses that complement and refine our analysis framework. One, EIA legislation may develop multilinearly in terms of ambition levels. Two, ambitions in EIA legislation seem to be influenced to a great extent by the power and capacity of, on the one hand, the environmental authorities supporting EIA and, on the other hand, the sector authorities hindering the development of EIA. Three, the political system is the most important context factor influencing the rules of policy-making and the power of the different actors involved. Four, the importance of context factors on the development of ambitions is dependent on the phase of EIA system development. Five, some ambitions seem to be influenced by particular factors; for instance the ambitions for the object of study seem to be influenced by the level of environmental awareness of the sector ministries and parliament.

    1989-01-01

    On the basis of the lateral and vertical distribution of the lithofacies identified within the Late Jurassic Amran sequence (Thoma Member) in Jabal Al-Balaq area, Marib, Y.A.R., three megafacies were recognized. Proceeding from the shore landwards they are: Ooid bank, including barriers such as reefs and carbonate sand shoals adjacent to the margin of a shallow platform having intertidal to subtidal agitated water, the bank being composed of skeletal packstone, oolitic grainstone and oncolitic packstone; Shelf lagoon, behind the shoal, characterized by less turbulent pelletoidal wackestone, sandy mudstone and algal stromatolite (boundstone); Alluvial coastal plain, including tidal sand flat of the marine shoreline-intertidal area, where cross-bedded sandstone and alluvial fan toe conglomerate were deposited. The apparent small-scale facies variations which are the result of the allocyclic tectonically controlled sea level fluctuations, reflect a complex interfingering of the depositional environments and the resulting rock types. The paragenetic sequence of the post-depositional processes within the siliciclastics inferred is: iron oxide cementation, authigenic growth of mica clays, generation of pressure solution and compaction, and generation of quartz overgrowths. It is indicated that the compaction process followed the neomorphism and cementation within the carbonates.

    This document describes the contents of a digital database containing maximum potential aboveground biomass, land use, and estimated biomass and carbon data for 1980. The biomass data and carbon estimates are associated with woody vegetation in Tropical Africa. These data were collected to reduce the uncertainty associated with estimating historical releases of carbon from land use change. Tropical Africa is defined here as encompassing 22.7 x 10{sup 6} km{sup 2} of the earth's land surface and is comprised of countries that are located in tropical Africa (Angola, Botswana, Burundi, Cameroon, Cape Verde, Central African Republic, Chad, Congo, Benin, Equatorial Guinea, Ethiopia, Djibouti, Gabon, Gambia, Ghana, Guinea, Ivory Coast, Kenya, Liberia, Madagascar, Malawi, Mali, Mauritania, Mozambique, Namibia, Niger, Nigeria, Guinea-Bissau, Zimbabwe (Rhodesia), Rwanda, Senegal, Sierra Leone, Somalia, Sudan, Tanzania, Togo, Uganda, Burkina Faso (Upper Volta), Zaire, and Zambia). The database was developed using the GRID module in the ARC/INFO{trademark} geographic information system. Source data were obtained from the Food and Agriculture Organization (FAO), the U.S. National Geophysical Data Center, and a limited number of biomass-carbon density case studies. These data were used to derive the maximum potential and actual (ca. 1980) aboveground biomass values at regional and country levels. The land-use data provided were derived from a vegetation map originally produced for the FAO by the International Institute of Vegetation Mapping, Toulouse, France.

    Evaluation of eight wells (seven offshore and one onshore) in Yemen and nine wells (two offshore and seven onshore) in Somalia, and a regional interpretation of all geophysical data available from ministry files in Yemen and Somalia has been carried out under the auspices of the World Bank-executed Red Sea/Gulf of Aden Regional Hydrocarbon Study Project. A northwest-southeast pre-Oligocene structural trend affecting the onshore pre-rift Mesozoic and early Tertiary rocks has been overprinted in the offshore by an east-west-trending extensional fault system forming the Gulf of Aden, and segmented by a series of northeast-southwest-trending left-lateral sets of transform faults. Free oil 42-44 API was recovered from Sharmah-1 well from the Eocene Habshiya limestone in Yemen and from the Late Jurassic Wanderer limestone (10-35{degree} API) at Dagah Shabei-1 well in Somalia. Geochemical analyses performed on well cuttings and a review of company data identify oil-sourcing potential in the pre-rift Upper Jurassic, Lower to Upper Cretaceous, and Paleocene to Eocene in Yemen, and Upper Jurassic and Upper Cretaceous in Somalia. The geothermal gradients (3.5C/100m) and maturation data (vitrinite reflectance, thermal alteration index, and T{sub max}) in the Gulf of Aden wells in the Yemen and Somali offshore imply that the oil window is relatively shallow (1,750-3,500 m). Relatively thin Paleogene in the Gulf of Aden area suggests that the Mesozoic and Lower Tertiary sediments which contain multiple source and reservoir sequences are situated within the oil window, and thus are highly prospective for oil and gas.

    A concerted effort to further develop productive capacity is evident in most Middle Eastern Countries, through exploration, field development, and secondary recovery. Saudi Arabia, Iraq, and Abu Dhabi all plan expanded petroleum industry programs in 1980. Oil production in Saudi Arabia through the first one-half of 1980 averaged 9.5 million bpd, and the Saudis are proceeding with the large-scale associated gas utilization and industrialization program. Iraq's near-term interest is in development of the Majnoon Discovery. Abu Dhabi is continuing efforts to complete development of a giant offshore field and finalize an onshore/offshore associated gas utilization facility. Only Iran and Kuwait are expected to be relatively inactive in petroleum programs during the remainder of 1980. Individual country reports are presented for Saudi Arabia, Iraq, Abu Dhabi, Dubai, Iran, Kuwait, the Divided Neutral Zone, Qatar, Oman, Bahrain, Syria, Turkey, Israel, Jordan, South Yemen, and Yemen Arab Republic.

    1988-11-14

    For the past 5 years the Organization of Petroleum Exporting Countries has been telling oil producers around the world that it can no longer carry the burden of trying to balance supply and demand without outside help. Non-OPEC exporters have, on several occasions, examined the benefits of sharing the burden of production cuts, but rightly have been nervous of close cooperation with an unpredictable and undisciplined competitor. Cooperation will certainly depend on OPEC reaching its own production cutting agreement. That must be done in a way that given non-OPEC countries confidence that any new production and pricing pact will not fall apart during the first half of next year. OPEC exports to the developing world have been trimmed by the advent of new producers. In most of these countries local production only eliminates or reduces imports. Few are in the class of North Yemen where the initial flow could meet local demand and provide a surplus for export.

    The traditional exploration cycle is in progress around the world, and many more exploration opportunities are becoming available than are being foreclosed. Yemen, for instance, is one of the few countries in the Middle East open to exploration by outside operators. Reserves were estimated at 4 billion bbl of oil on January 1, 1993, and the potential is widely believed to be much greater. Australia is opening 2 million acres offshore in the Vulcan sub-basin this month along with small parcels in the Bonaparte Gulf and more southerly basins. Several tracts have become available off Newfoundland, including two in proximity to giant Hibernia oil field scheduled for development this decade. Recent announcement of the first oil company licensing round in the Falkland Islands offshore has stimulated interest in that area. The paper discusses exploration potential in these four areas.

    Estimates of seismic horizontal ground acceleration and velocity having a 90 percent probability of nonexceedance in 100 yr in western Saudi Arabia indicate the highest relative levels of ground motion are expected in regions neighboring the Gulf of Aqaba and North Yemen. Estimated ground motions within the Arabia Shield are relatively low; whereas the central and northern coastal plan regions are characterized by intermediate-level ground-motion values that are governed by far-field effects of earthquakes in the central Red Sea Rift. The seismic hazard estimates were derived from regional seismic source zones that are based on interpretation relating potential seismic activity to the Precambrian through Tertiary structural framework of the region.

    1991-12-01

    International projects will be the major exploration focus during 1992. New opportunities continue to become available, as the world's governments and major national oil companies are changing their monopolistic policies to allow joint ventures within the industry. Exploration within the U.S. by major oil companies will continue to decrease, while the independents are expected to maintain modest prospecting activity. The opportunity to participate in a billion-barrel oil discovery will continue to attract both the major oil companies and independents to international exploration. A good example is the recently announced discovery in Colombia's Llanos basin. Large exploration programs are active currently in several countries that opened their doors to the industry in recent years-notably, Yemen, Myanmar, Peru and Algeria. This paper reports that these countries are under-explored, and the potential exists for large discoveries.

    Middle Eastern Power systems have evolved independently of each other over many decades. The region covers a wide geographical area of over 4 million square kilometers with an estimated population in 1990 of over 120 million people. This paper discusses the present status and future power system developments in the Middle East with emphasis on the Mashrequ Arab Countries (MAC). MAC consists of Egypt, Iraq, Jordan, Lebanon, Syria, Yemen, and the six Gulf Cooperation Council (GCC) countries, namely, Bahrain, Kuwait, Qatar, Saudi Arabia, Oman, and the United Arab Emirates (UAE). Interconnections within MAC and possible extensions to Turkey, Europe, and Central Africa are discussed. A common characteristic of the MAC power systems is that they are all operated by government or semi-government bodies. The energy resources in the region are varied. Countries such as Iraq, Egypt, and Syria have significant hydro power resources. On the other hand, the GCC countries and Iraq have abundant fossil fuel reserves.

    1982-07-01

    Worldwide offshore exxloration levels reached new highs during the past year. A large gas find was made off northern Norway at 72/sup 0/N lat. Oil was discovered off Abu Dhabi in the Persian Gulf, and off South Yemen and southeastern India. North Sea activity slowed because of increased taxes. Off the U.S., new frontier zones were leased, at water depths up to 7,000 feet. A large oil discovery was made off southern California. The Chinese continental shelf was opened for bidding. The world oil surplus and lower crude prices have resulted in budget trimming for offshore development and there will probably be a decline in overall exploration expenditures in 1982-1983.

    The Middle East remains today the global energy fulcrum. One year after the Persian Gulf war, the region is in greater turmoil and political uncertainty than it has known in modern times. The Iraqi invasion of Kuwait and subsequent external military intervention forced neighboring states to question the need for a foreign military presence in the future. The rift between the secular revolutionary states in the region led by Iraq, Libya, Yemen, Algeria, and Syria and the traditional monarchy of Saudi Arabia and the emirates of the gulf has widened. Egypt provides, at present, an uncomfortable bridge. The balance of political forces may be shifting. This paper attempts to answer the following questions: Where will we see the new leadership in the Middle East Will it again play a role through the Organization of Petroleum Exporting Countries and determination of the oil price in shaping the structure of global energy supply and demand

    About 30 billion bbl of recoverable oil have been found in new foreign plays during the last 5 years; significant gas reserves also were found. Most of the foreign oil discoveries are in Mesozoic sandstone reservoirs onshore, but Marlim, the largest single field with estimated reserves of 2.5 billion bbl, is located offshore in the deep-water part of the Campos basin, Brazil. Approximately 8-10 billion bbl of oil were found in South America, 6 billion in the Near East, 5 billion in western Europe, 5 billion in Africa, 2 billion in Asia (outside the USSR), and 0.5-0.7 billion in Australasia. Some of the giant discoveries include: Cano Limo, Colombia (1983); Alif, North Yemen, and Draugen, Norway (1984); Marlim, Brazil, and Heidrun, Norway (1985); El Furrial, Venezuela (1986); and Musipan-1, Venezuela (1987). Most of these and several smaller discoveries are in new plays or trends.

    1996-08-01

    A Satellite Remote Sensing Technique is demonstrated for generating near surface geological structure data. This technique enables the screening of large areas and targeting of seismic acquisition during hydrocarbon exploration. This is of particular advantage in terrains where surveying is logistically difficult. Landsat Thematic Mapper (TM) data and a high resolution Digital Elevation Model (DEM), are used to identify and map outcropping horizons. These are used to reconstruct the near surface structure. The technique is applied in Central Yemen which is characterised by a {open_quote}layer-cake{close_quote} geological and low dipping terrain. The results are validated using 2D seismic data. The near surface map images faults and structure not apparent in the raw data. Comparison with the structure map generated from a 2D seismic data indicates very good structural and fault correlation. The near surface map successfully highlights areas of potential closure at reservoir depths.

    The study endorses the proposed terms of reference for the feasibility study of the Mahreb Power Generation Project in Yemen. It is a reasonable and practical approach to meet the immediate need for additional power in the country. The outline for the feasibility study also seeks a long term solution for an economic and technically sound power generating system to meet future power needs. U.S. firms have been competitive in international tenders for supplying the type of services and equipment needed for the Mahreb Power Project. Because it is a gas turbine power generation project and the opportunities it offers US equipment manufacturers and contractors, the study recommends that the U.S. Trade and Development Program (TDP) fund the feasibility study.

    A Satellite Remote Sensing technique is demonstrated which provides accurate and cost effective near-surface geological structure data. In the exploration phase the technique enables the rapid and inexpensive screening of open licences and the targeting of seismic acquisition, particularly important in terrains of difficult data acquisition. This paper describes the satellite data used, the technique of horizon surface data extraction and the analysis of a case study from Yemen. Landsat Thematic Mapper (TM) data and a high resolution digital elevation model (DEM), generated from stereo SPOT panchromatic images, are used in conjunction to identify a number of outcropping horizons and map their spatial position and height. Geological contacts are identified and digitised from the Landsat TM data and the elevations of these points taken from the digital elevation data. The extracted x,y,z co-ordinates are then gridded to construct a horizon structure map. The technique is applied to an area of central Yemen which is characterised by a near-surface {open_quote}layer cake{close_quote} geological structure in an extremely low dipping terrain (Less than 1{degrees}). The remote sensing interpretation is validated by comparison with 2D seismic across the area. Regional flexural structures with bed dips of as little as 0.25{degrees} can be mapped. Trend analysis and residual calculations on the horizon structure map show the techniques ability to identify and quantify horizon deformation related to faulting. Surface geological structure was successfully interpolated into the subsurface indicating potential fault closure at reservoir target depths.

    This paper describes research efforts of The Global Livestock Producers Program (GLPP) in establishing self-sustaining enterprises for cost-effective technologies (i.e., animal nutrition and genetic improvement) and global methane emissions reductions in developing world nations. The US Environmental Protection Agency has funded several studies to examine the possibilities of reducing ruminant methane emissions in India, Tanzania, Bangladesh, and Brazil. The results of the studies showed that: (1) many developing countries` production systems are inefficient, and (2) great potential exists for decreasing global methane emissions through increasing animal productivity. From this effort, the GLPP established livestock development projects in India, Zimbabwe, and Tanzania, and is developing projects for Bangladesh, Nepal, and Brazil. The GLPP has developed a proven methodology for assessing ruminant methane and incorporating methane emissions monitoring into viable projects.

    The Mashreq Arab countries covered in this study are Bahrain, Egypt, Jordan, Lebanon, Oman, Qatar, Saudi Arabia, Syria, the United Arab Emirates, and Yemen. A feasibility study for the interconnection of the electrical networks of the Mashreq Arab countries, sponsored by the Arab Fund, was completed in June 1992. Each country is served by one utility except Saudi Arabia, which is served by four major utilities and some smaller utilities serving remote towns and small load centers. The major utilities are the Saudi consolidated electric Company in the Eastern Province (SCECO East), SCECO Center, SCECO West, and SCECO South. These are the ones considered in this study. The Mashreq Arab region has a considerable mix of energy resources. Egypt and Syria have some limited amounts of hydropower resources, and the Arabian Gulf region is abundant in fossil fuel reserves. Owing to the differences in energy production costs, a potential exists for substantial energy trading between electric utilities in the region. The major objective of this project is to study the feasibility of electric energy trading between the Mashreq Arab countries. The basis, assumptions, and methodologies on which this energy trading study is based relate to the results and conclusions arising out of the previous study, power plant characteristics and costs, assumptions on economic parameters, rules for economy energy exchange, etc. This paper presents the basis, methodology, and major findings of the study.

    Power system interconnection is a well established practice for a variety of technical and economical reasons. Several interconnected networks exist worldwide for a number of factors. Some of these networks cross international boundaries. This presentation discusses the future developments of the power systems of Mashreq Arab Countries (MAC). MAC consists of Bahrain, Egypt, Iraq, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, United Arab Emirates (UAE), and Yemen. Mac power systems are operated by government or semigovernment bodies. Many of these countries have national or regional electric grids but are generally isolated from each other. With the exception of Saudi Arabia power systems, which employ 60 Hz, all other MAC utilities use 50 Hz frequency. Each country is served by one utility, except Saudi Arabia, which is served by four major utilities and some smaller utilities serving remote towns and small load centers. The major utilities are the Saudi Consolidated electric Company in the Eastern Province (SCECO East), SCECO Center, SCECO West, and SCECO South. These are the ones considered in this study. The energy resources in MAC are varied. Countries such as Egypt, Iraq, and Syria have significant hydro resources.The gulf countries and Iraq have abundant fossil fuel, The variation in energy resources as well as the characteristics of the electric load make it essential to look into interconnections beyond the national boundaries. Most of the existing or planned interconnections involve few power systems. A study involving 12 countries and over 20 utilities with different characteristics represents a very large scale undertaking.

    Upper Jurassic carbonates, Lower Cretaceous sands, Lower Cretaceous carbonates and Tertiary carbonates of the Middle East contain more than 50% of the worlds oil. Our area of interest covers SE Turkey and Syria in the north to the borders of Yemen and Oman in the south, and from the Red Sea across Saudi Arabia, the Emirates and the Arabian/Persian Gulf to Iran in the East. There are over 80 fields in this region with over 1 billion barrels of recoverable reserves. Yet only around 30,000 wells have been drilled in this territory. Regional structure and stratigraphy are discussed within the context of three major plays in the region as well as a new play in the Permo-Carboniferous. Numerous opportunities are available and countries such as Iraq and Iran may one day open their doors more to the industry than is presently the case. The dramatic petroleum geology of the region will stamp its influence on the nature of business and opportunities for years to come. While fiscal systems here already offer some of the toughest terms in the world, future deals in the more prolific areas will be even tougher. But, the economies of Middle Eastern scale will provide some of the great mega-opportunities of future international exploration.

    Twenty years ago, remote sensing promised to revolutionize exploration; unfortunately, many of the early promises made were unfulfilled and remote sensing tended to drop out of mainstream exploration. Both these extremes are unrealistic, and projects undertaken by Clyde in Yemen illustrate some of the ways remote sensing can become a successful and cost-effective part of an exploration program. Firstly, the remote sensed data, integrated with a minimum of ground control work, provided maps to use in subsequent fieldwork, a surface geology map, and a digital elevation model with its derived topographic contour maps. Secondly, the remote sensed data enabled the authors to create a structural contour map of a near surface horizon at a very low cost per square kilometer. Thirdly, the remote sensed data became a crucial planning tool for seismic operations to optimize data quality and minimize acquisition cost without having to resort to costly and time-consuming swath shooting or similar high-effort techniques. Finally, the surface geological map derived from the image interpretation enabled them to create geological cross sections along the shot seismic lines in a matter of hours without having a field geologist mapping along the lines. Remote sensing can provide highly cost-effective benefits to an exploration program in an arid region, and many of the applications can also be developed for use in areas with vegetation cover.

    This paper reports that oil and gas companies in the US are curbing costs and redirecting spending to survive the worst decline of petroleum industry activity on record. Persistently weak US natural gas prices and shaky oil prices worldwide have put pressure on domestic companies to become low cost producers. Efforts to cut exploration and development costs have depressed activity in the US, one of the world's most mature oil and gas provinces. International E and D hot spots include the UK North Sea, Yemen, Thailand, Myanmar, Pakistan, and Latin America. Prospects in the Commonwealth of Independent States also continue to generate considerable enthusiasm. Operators struggling to survive or searching for funds to spend on non-US prospects are trying to shuck noncore US assets. Other favored cost cutting strategies include reducing and restructuring debt, operating and administrative staffs, and internal organizations. Major integrated companies are able to add value by refocusing refining, petrochemical, or marketing operations. But independents must adapt operations close to the wellhead to become low cost producers. Whatever tactics are used to mitigate effects of low US activity, no domestic company --- from the largest integrated major to the smallest independent producer --- has proven to be immune from the downturn.

    This paper describes how data from a variety of sources are merged to present new countrywide maps of the solar energy distribution over Ethiopia. The spatial coverage of stations with radiation data was found to be unsatisfactory for the purpose of a countrywide solar energy assessment exercise. Therefore, radiation had to be predicted from sunshine hours by employing empirical models. Using data from seven stations in Ethiopia, linear and quadratic correlation relationships between monthly mean daily solar radiation and sunshine hours per day have been developed. These regional models show a distinct improvement over previously employed countrywide models. To produce a national solar-energy distribution profile, a spatial extension of the radiation/sunshine relationships had to be carried out. To do this, the intercepts(a) and slopes(b) of each of the seven linear regression equations and another six from previous studies, completed in neighbouring Sudan, Kenya and Yemen, were used to interpolate the corresponding values to areas between them. Subsequent to these procedures, 142 stations providing only sunshine data were assigned their `appropriate` a and b values to estimate the amount of solar radiation received, which was then used to produce annual and monthly solar radiation distribution maps for Ethiopia. The results show that in all regions solar energy is an abundant resource. 19 refs., 11 figs., 4 tabs.

    The international oil and gas exploration and production industry faces a vast array of environmental issues that are global in nature but play an increasingly prominent role in individual project decision making. When placed against a backdrop of socio-political and cultural challenges presented in developing countries, project planners require an enlightened approach to ensure the environmental, economic and social components are appropriately balanced to ensure sustainable business success. Although a relatively new player in the international E & P industry, Canadian Occidental Petroleum Ltd. has developed such an approach to EMS management for projects in developing countries. Drawing from recent experience with a major project in Yemen, and others in the planning stages in several other developing countries, this paper presents a number of positive strategies and actions which are being applied in the many countries in which the company is active. Lessons learned and opportunities for improvement are presented for consideration by responsible operators working internationally toward the goal of environmentally sustainable energy development.

    The Huqf Group is the oldest known sedimentary sequence overlying crystalline basement in the Sultanate of Oman. It crops out on a broad regional high, the Huqf Axis, which forms a dominating structural element on the southeastern edge of the Arabian peninsula. Subsurface and outcrop evidence within and outside of Oman suggests that the sediments of the Huqf Group lie within the age span of late Precambrian to Early-Middle Cambrian. The Huqf Group is subdivided into five formations corresponding to an alternation of clastics (Abu Mahara and Shuram Formations) and carbonates (Khufai and Buah Formations) deposited in essentially shallow marine to supratidal (or fluviatile) conditions and terminated by an evaporitic sequence (Ara Formation). Evaporites are absent on the Huqf Axis, but they are thickly developed to the west over a large part of southern and central Oman, where they acted as the major structure former of most of Oman's fields, and even locally pierced up to the surface. Regional correlations suggest that the predominantly carbonate-evaporitic facies of the Huqf Group was widely distributed in late Precambrian-Early Cambrian time: the Huqf basin is tentatively considered part of a belt of evaporitic basins and intervening carbonate platforms, which stretched across the Pangea landmass from the Indian subcontinent (Salt Range of Pakistan) through South Yemen, Oman, and Saudi Arabia into the gulf states and Iran (Hormuz Series and carbonate platform north of the Zagros).

  16. Exploration into 1990s will still be shaped by politics, economics

    Frontier exploration plays continue to yield sizable oil and gas discoveries, despite recent wide fluctuations in the price of crude that have altered exploration budgets and curtailed activity. Amauligak in Canada, Colombia's Cano Limon, Albacora and Marlim in Brazil, the Haltenbank prospects offshore Norway, North Yemen's Alif field, and lagifu in Papua New Guinea are all examples of the occasional reward of a giant field. With a stable oil price of between $15-18/bbl during 1987, international exploration levels will slowly recover. And it is likely that an average $18/bbl price for the year will be sufficient to put a number of deferred development projects back on track. Activity levels will still vary widely from region to region and country to country however, controlled by political as well as economic conditions. Exploration was hit especially hard in the U.S., where finding and development costs are high. Operators continued to spend a greater share of their exploration funds outside the U.S. in 1987.

    Significant rightholding changes took place in central and southern Africa during 1987. Angola, Benin, Congo, Gabon, Ghana, Guinea, Guinea Bissau, Mauritania, Seychelles, Somali Republic, Tanzania, Zaire, and Zambia announced awards or acreage open for bidding. Decreases in exploratory rightholdings occurred in Cameroon, Congo, Cote d'Ivoire, Equatorial Guinea, Gabon, Kenya, Namibia, South Africa, and Tanzania. More wells and greater footage were drilled in 1987 than in 1986. Total wells increased by 18% as 254 wells were completed compared to 217 in 1986. Footage drilled during the year increased by 46% as about 1.9 million ft were drilled compared to about 1.3 million ft in 1986. The success rate for exploration wells in 1987 improved slightly to 36% compared to 34% in 1986. Significant discoveries were made in Nigeria, Angola, Congo, and Gabon. Seismic acquisition in 1987 was the major geophysical activity during the year. Total oil production in 1987 was 773 million bbl (about 2.1 million b/d), a decrease of 7%. The decrease is mostly due to a 14% drop in Nigerian production, which comprises 60% of total regional production. The production share of OPEC countries (Nigeria and Gabon) versus non-OPEC countries of 67% remained unchanged from 1986. 24 figs., 5 tabs.

    A microcosm of what was, what is, and hopefully what will be, is embodied in South Africa`s coal industry-the sixth largest in the world, the third largest in coal exports behind the United States and Australia, and the second largest in the world`s steam coal trade behind Australia. Mining is the international, economic life blood of South Africa. In total, the country exports 60 minerals to 80 countries, providing on a raw basis for 43% of the nation`s international trade, and as much as 60% when beneficiated products are included. The nation`s coal fields lie in the northeastern section of the country, running south from the Botswana-Zimbabwe-Mozambique borders, principally in the Transvaal, Natal, and Orange Free State provinces. The coal seams run in thickness from 2.5 to 8 m, with an average overburden thickness of 80 m. The coal industry provides 83% of the country`s commercial energy and 52% of all the electric power consumed on the entire continent. Seen from the air, the veld around Johannesburg is dotted with power plants-virtually all coal-fired. There is only one nuclear plant and two hydroelectric produced in South Africa comes from Eskom, the state-owned utility, and 90% total comes from coal-fired units.

  19. Geological and environmental remote sensing for international petroleum operations

    Remote sensing allows the petroleum industry to make better and quicker interpretations of geological and environmental conditions in areas of present and future operations. Often remote sensing (including aerial photographs) is required because existing maps are out-of-date, too small of scale, or provide only limited information. Implementing remote sensing can lead to lower project costs and reduced risk. The same satellite and airborne data can be used effectively for both geological and environmental applications. For example, earth scientists can interpret new lithologic, structural, and geomorphic information from near-infrared and radar imagery in terrains as diverse as barren desert and tropical jungle. Environmental applications with these and other imagery include establishing baselines, assessing impact by documenting changes through time, and mapping land-use, habitat, and vegetation. Higher resolution sensors provide an up-to-date overview of onshore and offshore petroleum facilities, whereas sensors capable of oblique viewing can be used to generate topographic maps. Geological application in Yemen involved merging Landsat TM and SPOT imagery to obtain exceptional lithologic discrimination. In the Congo, a topographic map to plan field operations was interpreted from the overlapping radar strips. Landsat MSS and TM, SPOT, and Russian satellite images with new aerial photographs are being used in the Tengiz supergiant oil field of Kazakhstan to help establish an environmental baseline, generate a base map, locate wells, plan facilities, and support a geographical information system (GIS). In the Niger delta, Landsat TM and SPOT are being used to plan pipeline routes and seismic lines, and to monitor rapid shoreline changes and population growth. Accurate coastlines, facility locations, and shoreline types are being extracted from satellite images for use in oil spill models.

    The International Research Center for Energy and Economic Development (CEED) has undertaken a number of activities involving research, publications, and conferences to meet its stated objective of stimulating knowledge in the fields of energy and economic development. The Shadow OPEC area conference sought to trace and weigh primarily the emergency of those seven countries which, for several years prior to 1989, had been in touch with the Organization of the Petroleum Exporting Countries (OPEC) through special missions. Among the major questions addressed in the sessions were: How do Angola, China, Colombia, Egypt, Malaysia, Mexico, and Oman envisage their energy policies within this bloc and within the wider context of possible cooperation with OPEC What will be the impact on other non-OPEC Producers, such as Norway, North Yemen, Canada, the USSR, and certain US states of a closer relationship between OPEC and its shadow group of seven The international energy conference on A Reintegrated Oil Industry was designed to evaluate and assess the trends evident within the oil and gas industry worldwide that include the relatively new arrangements between producer-country firms and other energy companies, largely those in the consuming, importing nations. These arrangements involved stockholding buyouts of downstream facilities, joint ventures, and other approaches. What effect are such developments expected to have on investment, market share, security of supply, exploration, investment, pricing, and even privatization ICEED has selected the title of Energy Watchers for the series under which to publish these proceedings as well as forthcoming conferences. Papers have been processed separately for inclusion on the data base.

    The potential of hydrogen generation in the Red Sea and Gulf of Aden was studied by geochemical analyses of 2,271 samples from 23 wells drilled in 6 countries within the area. Selection of candidate source beds was primarily a function of the sedimentary column penetrated by drilling (i.e., whereas sub-Tertiary sediments are accessible in Somalia and Yemen in the Gulf of Aden, sampling below the thick Neogene evaporitic sequence in the Red Sea could not be achieved due to a general lack of penetration to such levels). Organic matter content and type, maturity levels, petroleum potential of the rock analyzed, and its capacity to have generated liquid or gaseous hydrocarbons are the basic results provided by the analyses. Geochemical well correlations within and between subbasins are presented using the two most representative parameters: total organic carbon (TOC) and Petroleum Potential (PP = S{sub 1} + S{sub 2}), expressed in kilograms of hydrocarbons per ton of rock. In general, results obtained in the two rift basins, with sampling mostly in Neogene sediments in the Red Sea and in sub-Tertiary and Tertiary sediments in the Gulf of Aden, indicate the presence of favorable sources preferentially in this sub-Tertiary succession. It is stressed that geochemical analysis results are from wells whose locations are generally on structural highs and, therefore, are not representative (especially in terms of maturation) of conditions in adjacent depressions, particularly where the difference in structural level is great. Sound simulation modeling makes possible the reconstruction regional thermal and burial history and, thus, identification of maturation kitchens.

    Crustal structure in southern Africa has been investigated by jointly inverting receiver functions and Rayleigh wave group velocities for 89 broadband seismic stations spanning much of the Precambrian shield of southern Africa. 1-D shear wave velocity profiles obtained from the inversion yield Moho depths that are similar to those reported in previous studies and show considerable variability in the shear wave velocity structure of the lower part of the crust between some terrains. For many of the Archaean and Proterozoic terrains in the shield, S velocities reach 4.0 km/s or higher over a substantial part of the lower crust. However, for most of the Kimberley terrain and adjacent parts of the Kheis Province and Witwatersrand terrain, as well as for the western part of the Tokwe terrain, mean shear wave velocities of {le} 3.9 km/s characterize the lower part of the crust along with slightly ({approx}5 km) thinner crust. These findings indicate that the lower crust across much of the shield has a predominantly mafic composition, except for the southwest portion of the Kaapvaal Craton and western portion of the Zimbabwe Craton, where the lower crust is intermediate-to-felsic in composition. The parts of the Kaapvaal Craton underlain by intermediate-to-felsic lower crust coincide with regions where Ventersdorp rocks have been preserved, and thus we suggest that the intermediate-to-felsic composition of the lower crust and the shallower Moho may have resulted from crustal melting during the Ventersdorp tectonomagmatic event at c. 2.7 Ga and concomitant crustal thinning caused by rifting.
