Enhancing Structural Analysis with the Fourier Transform - An Example from the Berkine Basin, Algeria
Authors W. I. Taylor and F. J. GauthierThe primary challenge of structural geologists in the petroleum industry is to characterize the spatial distribution of folds, faults, and joints in the subsurface and to understand how these features effect the migration and entrapment of hydrocarbons. In most cases, subsurface data are insufficient to accurately characterize rock deformation at the desired scale. As a result, conceptual models are invoked to help translate sparse data sets into structural interpretations. The selection of an appropriate model is often lelt to intuition or is based on a "common perception" that has not been verified.

High-Resolution Chemostratigraphy, Biostratigraphy and Paleoceano-Graphic Significance of the Thetyan "Livello Selli" from the Hybla Formation, Nw Sicily
Authors A. Bellanca, E. Erba, R. Neri, I. Premoli Silva, M. Sprovieri, F. Tremolada, D. Verga, F. Meli and G. PetroloHigh-resolution curves of carbon and oxygen isotopes and of major and trace elements have been generated for the early Aptian "Livello Selli" (LS, OAE la) from the pelagic sedimentary sequence outcropping at Calabianca in the northwestern margin of Sicily.

Late Cretaceous Geological History of Zaltan Platform (Concession 59), South Central Sirt Basin, Libya
Authors M. M. Abu Gares and M. T. El BakaiThe Late Cretaceous stratigraphic sequences are widespread and consist of marine shale and limestone ranging in age from the Turonian up to the Maastrichian. In the study area the sequence of the Late Cretaceous is divided into five clearly recognizable formations.

Exploration Potential in the Offshore Mediterranean, Egypt - Perspectives from the Context of Egypt's Future Resources and Business Challenges
Authors J. C. Dolson, P. J. Boucher and M. V. ShannEgypt has developed 15.4-17 BBOE equivalent resources in three major geological provinces in the last 100 years of exploration. Nine billion barrels have been discovered in the mature province of the Gulf of Suez, an additional 2.5 BBOE in the Western Desert and 25 TCF (4.1 BBOE) in the onshore and offshore Mediterranean Nile Delta. Future growth potential will come primarily from deeper pool Jurassic age reservoirs in the Western Desert and from deep water exploration in the Mediterranean sea.

Habitat and Exploration Potential of the Ultra-Deepwater Offshore Mediterranean
Authors A. Abdel Aal, A. El Barkooky, M. Gerrits, H. Mayer, M. Schwander and H. ZakiThe Northeast Mediterranean Deepwater Block lies in water depths of 800m to 2800m in front of the Nile Delta Cone. The Block is exceptional for its site (41,500 km2), roughly equal to the total area presently licensed over the Nile Delta, which to date has yielded dry gas and gas/condensate. The structural and stratigraphic setting of the block offers a variety of hydrocarbon trapping possibilities similar to the deegwater settings of other productive deltas. This venture falls in the category of real frontier exploration opportunity.

Lower Congo Basin, Deepwater Exploration Province, Offshore West Africa
Authors J. Leite, T. W. Schirmer and B. R. LawsThe Lower Congo Basin lies offshore of the west coast of Africa and covers 115,000 square kilometers from the Republic of Congo to central Angola, in water depths extending to over 3500 meters. A large number of oil and gas fields occur in the basin (14 MMMBOEG produced and proven).

The Atlantic Deepwater between Tanger and Safi, Geology and Play Concepts
Authors M. Hssain and M. El MostaineThe study areas located in the northern part of Morocco extend a long the western cost between the cities Safi and Tangier. The continental platform covers an area of about 24,000 sq.km; however, the petroleum exploration zone extends in deep water under 200 m isobath (Fig. 1).

Gas Chimneys in the Nile Delta Slope and Gas Fields Occurrence
Authors K. Barsoum, M. Della Martera and A. Menardi NogueraGas chimneys" and "gas plumes", poor seismic data zones above gas-hearing structures, are quite common and characteristic in hydrocarbon productive basins. Scatterering of seismic energy causes poor data zones in the cap rock penetrated by leaked gas above a gas reservoir.

The Lower Pliocene Gas Sands of Offshore Israel and Gaza - A New Play in the Eastern Mediterranean Basin
By S. J. MaddoxAt the time of writing (August, 2000) seven consecutive wells have been drilled offshore Israel in a 15 month period, all of which have discovered gas in basal Pliocene sandstones. This remarkable run of success parallels that of the adjacent Nile Delta, offshore Egypt and has led to the Eastern Mediterranean becoming one of the most prolific new gas exploration plays in the world.

Depositional Model of the El Garia Formation, Lower Eocene - The Example of the Kef El Guitoune, Central Tunisia
Authors C-A. Hasler, E. Davaud and R. BoichardThe lower Eocene Metlaoui Group contains proven economic petroleum reserves onshore and offshore Tunisia and Libya and is still an exploration target (e.g. Bishóp, 1988). Since the Ypresian deposits located in Tunisia crop out in very good conditions and are well documented (see e.g. Moody and Grant, 1989, Loucks et al., 1998), they constitute a very good example of a carbonate ramp model applicable to a hydrocarbon field.

Tunisia Offshore a Basin Modelling Assisted Exploration History
More LessDuring mid 90's a basin modelling application was performed on the Tunisian Offshore in order to evaluate the residual potential, by using a 3D code applied in 2D along some regional depth converted sections. The lack of a full and proper regional seismic coverage did not permit a complete regional mapping of the whole sedimentary record necessary for a 3D application.

Review of the Remaining Potential in the Eastern Sirte Basin, Libya
Authors R. Gras and G. J. AmbroseIn the Sine Basin more than 1600 exploration wells drilled since 1956 have discovered an estimated total of 130 billion barrels of original oil-equivalent in place (Thomas 1995, Gras & Thusu 1996).

Geochemical and Stratigraphic Evolution of the Mediterranean in the Late Miocene
Authors R. Flecker, R. M. Ellam and W. KrijgsmanDespite decades of research, no consensus hypotheses for the cause of the Messinian Salinity Crisis has been reached; efforts are hampered by the lack of modern analogues for the saline giants. Recent research has illustrated the importance of pre-evaporite sediments in understanding the nature of the Mediterranean in the prelude to salt precipitation.

Maikop Series - Main Cenozoic Petroleum System of Caucasus-Skythian Region
Authors O. K. Bazhenova, N. P. Fadeeva and M. L. Saint-GermesThe object of investigation is Maikop Series (Oligocene-Lower Miocene) widespred within the Caucasus-Scyphian region. The predominantly clayey content of marine origin, mainly sapropellic type of OM, presence of oil and gas accumulations make these deposits the example of classic petroleum system.

The Interaction of Structural Style and Petroleum Accumulations in the Berkine Portion of the Ghadames Basin, Algeria
Authors F. J. Gauthier, L. Taylor and R. J. LunnThe Berkine portion of the Ghadames basin has yielded significant reserves in the last decade. The Great Eastern Erg of Algeria, although having been explored before in the 1970's and 1980's, has become one of the hottest petroleum provinces in the world with recent discoveries totaling well over 3 billion barrels of oil recoverable (figure 1).
