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.

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.

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).

Stratigraphic Architecture Of The Triassic Reservoir in The Saharan Province, Algeria
Authors G. Desaubliaux, R. Eschard, D. Bekkouche and A. HamelThe Triassic reservoir is one of the most prolific plays in Algeria since the beginring of the exploration. One of the exploration risk is linked to the distribution and heterogeneity of the reservoir: Triassic series were mostly deposited in continental to lagoonal depositional environments, and reservoirs mostly correspond to channelised fluvial sandstones interfingering with floodplain and sabbkha sediments.

Fracture Origin - Morphology and Reservoir Performance Improvement - Example of the Maastrichtian Chalky Limestones in Tunisia
Authors H. Troudi, H. El Euchi, C. El Maherssi and P. TremolieresBecause of the drastic increase in oil/gas discoveries where natural fractures play an important role in production (North sea, Middle east; USA, North Africa...), focus on fracture studies with an ultimate goal of fracturing on subsurface fluid flow and subsequent reservoir performance is of paramount importance in the reservoir evaluation and management.

Predictive Modelling of Fractured Reservoirs Using Geomechanics and Flow Simulation
Authors S. J. Bourne, A. Rijkels, B. J. Stephenson and E. J. M. WillemseTo optimise recovery in naturally fractured reservoirs, the field-scale distribution of fracture proporties must be understood and quantified. We present a semi-deterministic method to systematically predict the spatial distribution of natural fractures and their effect on recovery . The calculated field-scale fracture models are calibrated by geological, well test and field production data to constrain the distributions of fractures within the inter-well spaco.

Sedimentary Characters Changes in Fractured Micritic Reservoirs - Example of the Abiod-Bou Dabbous Formations in Northern Tunisia
Authors M. H. Negra, B. Mardassi and S. MelkFractured micritic reservoir rocks constitute in Tunisia additional hydrocarbon targets since the discovery of oil in some fields such as in Sidi el Kilani, Zinia, Belli, (Ben Ferjani et al. 1990) El Menzah etc.. In Tunisia, the main developed fractured micritic carbonates are constituted of the Campanian Abiod Formation (Burollet, 1956; Negra et al, 1994; Negra, 1998) and the Ypresian Bou Dabbous Formation (Fournié, 1978; Loocks et al, 1996).

Authors G. Cavinato and M. DaltástaThe study of various outcropping sequences in the central Apennines (Fig. 1), located in the central area of the Lazio-Abruzzii carbonate platform (Simbruini-Ernici Mt. and western Marsica), has allowed to make further remarks about the role of the Jurassic-Cretaceous synsedimentary tectonics on the paleogeographic and geodynamic evoIution of the study area during Neogene and Quaternary times.

Characteristics of Al Qarqaf Arch, the Ghadamis and Murzuq Basins, W. Libya - An Integration of RS, Seismic and Aeromagnetic Data
Authors Y. A. Al Fasatwi, P. M. van Dijk and A. A. MissilatiThe mapping of the arch structures of Libya, which separate most Libyan sedimentary basins from each other, can significantly enhance the understanding and modeling of their tectonic formation and deformation history. These arches were effective in localizing truncation, unconformities and onlap of depositional sequences. In addition, they are likely to be focal points for oil migration and accumulation.

Hydrocarbon Potential of Mediterranean Region
By H. RempelMediterranean region comprises the littoral states of the Mediterranean Sea. Seen in a global framework, the hydrocarbon reserves and production of these countries are relevant. Their combined share of world production lies between 5 and 6%, of the world reserves at about 4%, resources between 2 and 4%, consumption is higher (see fig. 1).

Libya - A New Depth-To-Basement Interpretation from Potential Fields Data Constrained by Well Data
Authors S. Z. Jassim, S. J. Campbell and I. W. SomertonOil exploration companies have collected gravity and magnetic data in Libya for over 50 years. In fact, potential field methods were among the original geophysical techniques used to map and delineate oil-bearing structures in Libya prior to the introduction of the seismic reflection method. They still remain cost effective methods, but now tend to be used in support of the seismic method.

Depositional Conditions of Mid-Eocene Nummulite Accumulations in the Gulf of Gabes, Tunisia
Authors M. K. Hauptman, J. Bartholdy and R. BischoffNummulitic limestones in the Gulf of Gabes and onshore Central Tunisia i.e. the Early Eocene (Ypresian) El Garia Formation and the Mid-Eocene Reineche Member are generally interpreted as hydrodynamic storm-derived nummulite accumulations. Such models try to explain the characteristic irregular bedding and scattering of nummulites by the occurrence of chaotic turbulent current patterns during storm events.

High Resolution Sr Isotope Stratigraphy in the Turonian-Maastrichtian Carbonates of the Periadriatic Domain
Authors R. Cestari and M. OrlandoThis poster shows briefly how in ENI Agip Division the Strontium Isotope Stratigraphy (SIS) is being applied as a stratigraphic tool. SIS is considered in addition to the classical paleontological analyses for dating purposes, when sedimentary rocks have no diagnostic fossil or when fossil assemblages are affected by bio-provincialism problems, and/or when a marked dependency on the facies/depositional mechanisms is observed.
