Modeling the Petroleum System - 2012
Petroleum systems modeling with testing of several scenarios was conducted in July 2012 using the acquired 2D seismic lines.
The results of the basin modeling improved the understanding of the petroleum systems offshore Lebanon and the conditions required for the generation of oil or gas and biogenic versus thermogenic gas.
The basin modeling aimed to estimate the average charge of the structures and to indicate the nature of fluids that are potentially trapped, ultimately improving the understanding of the petroleum systems potentially found offshore Lebanon.
The most prospective horizons as well as the most active petroleum systems were also identified.
3D Seismic Survey Offshore Lebanon, Southern Survey - 2012
The objective of the study was to assess the hydrocarbon prospectivity offshore southern Lebanon. A major improvement achieved from this study was the possibility to delineate several typical Mesozoic rimmed carbonate platforms.
The most important improvement for future exploration concerns the imaging of the faulted and folded structures linked to a strike slip fault system along the continental margin. Several elongated anticlines with closures can be delineated which deform the stratigraphic layers.
This allowed for the definition of 14 prospects and six plays of regional interest which is a positive element for exploration.
The modeling of the petroleum systems in offshore Lebanon realized in 2011 reinforces the potential resources of the prospects defined on the 3D southern survey area with good probability of gas presence. Potential direct hydrocarbon indicators (DHI) and flat spots are observed.
Seismic Interpretation and Characterization of 3D Survey Offshore Lebanon (Northern Survey) - 2012
In late-2012, the geology and geophysics department performed an interpretation of the 3D seismic survey acquired in 2007 totaling 660 km2.
The objective of the study was to assess the hydrocarbon prospectivity offshore northern Lebanon by interpreting and characterizing the 3D seismic northern survey. The northern survey is located on a major tectonic boundary between the Levant basin subducting to the north below the Cyprus arc and therefore the geologic framework is different to other zones offshore Lebanon.
A reservoir characterization was performed at this location that incorporates all the characteristics of the reservoir with respect to its ability to store hydrocarbons and also produce them. For the seismic reservoir characterization purpose, a pre-stack inversion was realized. The results, used for reducing interpretation uncertainties, confirm the presence of gas and improve the net-to-gross estimate of the potential reservoirs. The key result of the study, based on the 3D survey interpretation, is the definition of 25 prospects grouped into 7 structures, because the individual prospects are superimposed vertically, which increase the attractiveness of the area.
