Republic of Lebanon
Airborne geophysical acquisition surveys was undertaken by Neos Geosolutions in order to assess the hydrocarbon prospectivity onshore. The survey covered approximately 6000 km2, of which 2000 km2 covered the coast of Lebanon and 4000km2 onshore. Neos Geosolutions used two fixed-wing aircraft acquisition platforms outfitted with advanced sensors: one to perform Hyperspectral acquisition and the other to perform Magnetic, Electromagnetic, Radiometric and Gravitational (MERG) acquisition.
The hyperspectral survey began on Friday 3rd October, 2014 and was used to identify spectral signatures of direct and indirect indicators of hydrocarbons and minerals on the surface. The second plane arrived during the month of October, 2014. The MERG survey merged magnetic, electromagnetic, gravitational and radiometric surveys. Ground Magnetotelluric (MT) stations connected the airborne electromagnetic (EM) measurements with ground electromagnetic measurements to improve on measurement depths.
Neos Geosolutions typically works with Multi-Measurement interpretation (MMI) involving the integration of geological, geophysical, geochemical and petrophysical datasets including well logs, cores, two-dimensional (2D) and three-dimensional (3D) seismic lines. Neos initially interprets each data set individually, followed by qualitative multi-measurement interpretation whereby several datasets were interpreted in combination. Finally, Neos applied a variety of geostatistical and predictive analytic techniques to quantitatively interpret all relevant geologic and geophysical measurements, attributes and derivatives. The airborne acquisition surveys provided the ability to connect the onshore geologic and geophysical data to the offshore data. This was attained by incorporating onshore and offshore seismic data in the interpretation and integration of the transition zone along the coast of Lebanon providing vital insight into understanding the geology of Lebanon.
