3D Seismic Interpretation Western Offshore and South Eastern Margin Surveys - 2015
In early-2015, a 3D seismic interpretation study was performed with the objective of assessing the hydrocarbon prospectivity of western offshore and south-eastern margin of Lebanon by interpreting five 3D seismic surveys acquired by PGS and Spectrum in 2012 and 2013 totaling 8848 km2.
This study enables the surveyed area to be divided into three different prospective zones: the Lebanon western offshore (deep) Levant basin with three features that have important consequence on the definition of prospects in this domain and that have been better defined with the interpretation of the 3D; the Cyprus Arc Domain (northernmost western offshore) with the new 3D surveys covering the southern extension of structure previously identified from the 3D seismic interpretation of the northern survey and allowed for better understanding of the area; and the south eastern continental margin that had been better constrained with the 3D seismic interpretation.
The key result of the study is the definition of 45 prospects grouped into 17 structures, because the individual prospects are stacked vertically, which increases the attractiveness of the area. Eight (8) of them have an areal closure greater than 50 km2 and nineteen (19) of them have more than 25 km2 .
Neos Lebanon NeoBasin Study - 2015
In mid-2015, an interpretation study was performed on the data acquired from the airborne geophysical survey that covered 6000 km2, of which 2000 km2 covered the coast of Lebanon and 4000 km2 onshore.
The data interpreted support the presence of significant potential for discovery of hydrocarbons, and identified six areas of interest onshore and three areas of interest on the margin area. Furthermore, a dual seismic/gravity and magnetic interpretation was performed along parts of the 2D lines acquired by Spectrum that intersects with the gravity survey acquired by Neos. Poor seismic coverage and imaging quality on the margin had affected previous petroleum assessment, specifically in terms of risk assessment.
The airborne geophysical and magnetic field data reduced uncertainties associated with risk assessment calculated in previous studies. The data supported the presence of significant potential for discovery of hydrocarbons in Lebanon in the Triassic. Triassic and Paleozoic thermal analysis indicated wet gas transitioning to dry gas probable with some liquids possible. It is reported that there are six onshore areas of interest covering 2461 km2 and three offshore areas of interest covering 742 km2.
The study looks at the Triassic Reservoir only, and concentrates on the study area. The goals of the static (in-place volumes) calculations and uncertainty study are to determine volumes of gas in place.
