“…A key step in the workflow is the transfer of the stratigraphic modeling results to the petroleum system model to best account for petrophysical properties distribution in the basin. Geochemical parameters were integrated from previous source rock studies (Bou Daher et al, ). Further fluid migration scenarios were created considering selected fault systems (Ghalayini et al, ; Ghalayini, Homberg, Daniel, & Nader, 2017).…”

“…The two classes (oil and gas) kinetic schemes used for the six source rock intervals were defined after results from Bou Daher et al (), Bou Daher et al,(, Supporting Information Table S2) and reaction kinetics of hydrocarbon fractions were partly adjusted to allow for thermal secondary cracking (Table , Supporting Information Table S2).…”

“…Although the northern Levant Basin offshore Lebanon and Syria remains an underexplored province, several authors have recently addressed scientific questions related to its stratigraphic (Hawie, Deschamps, et al, ), geodynamic and structural evolution (Ghalayini, 2015 ; Inati et al, ; Symeou et al, ), and its source rock potential (Bou Daher, Nader, Müller, & Littke, ; Bou Daher, Nader, Strauss, & Littke, ).…”

“…The Neo‐Tethyan oceanic crust was partly subducted underneath Eurasia, eventually, giving rise to the Cyprus Arc (Figure ). Important facies changes occurred, including a major hiatus onshore Lebanon at least from the Coniacian and Lower Santonian that can be linked to a wide marginal uplift (Bou Daher et al, ; Müller et al, ). An equivalent Senonian unconformity was observed in offshore seismic data (Hawie, Deschamps, et al, ).…”

The Eastern Mediterranean Levant Basin is a proven hydrocarbon province with recent major gas discoveries. To date, no exploration wells targeted its northern part, in particular the Lebanese offshore. The present study assesses the tectono‐stratigraphic evolution and related petroleum systems of the northern Levant Basin via an integrated approach that combines stratigraphic forward modeling and petroleum systems/basin modeling based on the previous published work. Stratigraphic modeling results provide a best‐fit realisation of the basin‐scale sedimentary filling, from the post‐rift Upper Jurassic until the Pliocene. Simulation results suggest dominant eastern marginal and Arabian Plate sources for Cenozoic siliciclastic sediments and a significant contribution from the southern Nilotic source mostly from Lower Oligocene to Lower Miocene. Basin modeling results suggest the presence of a working thermogenic petroleum system with mature source rocks localised in the deeper offshore. The generated hydrocarbons migrated through the deep basin within Jurassic and Cretaceous permeable layers towards the Latakia Ridge in the north and the Levant margin and offshore topographic highs. Furthermore, the basin model indicates a possibly significant influence of salt deposition during Messinian salinity crisis on formation fluids. Ultimately, the proposed integrated workflow provides a powerful tool for the assessment of petroleum systems in underexplored areas.

“…The sample preparation was carried out perpendicular to bedding foliation by dry polishing with carbide abrasive papers down to 4000 grit. We followed the procedure in Littke et al (2012) andBou Daher et al (2014). Organic carbon measurements were performed with a liquiTOC II analyzer.…”

Abstract. We studied gouge from an upper-crustal, lowoffset reverse fault in slightly overconsolidated claystone in the Mont Terri rock laboratory (Switzerland). The laboratory is designed to evaluate the suitability of the Opalinus Clay formation (OPA) to host a repository for radioactive waste.The gouge occurs in thin bands and lenses in the fault zone; it is darker in color and less fissile than the surrounding rock. It shows a matrix-based, P-foliated microfabric bordered and truncated by micrometer-thin shear zones consisting of aligned clay grains, as shown with broad-ion-beam scanning electron microscopy (BIB-SEM) and optical microscopy. Selected area electron diffraction based on transmission electron microscopy (TEM) shows evidence for randomly oriented nanometer-sized clay particles in the gouge matrix, surrounding larger elongated phyllosilicates with a strict P foliation. For the first time for the OPA, we report the occurrence of amorphous SiO 2 grains within the gouge. Gouge has lower SEM-visible porosity and almost no calcite grains compared to the undeformed OPA.We present two hypotheses to explain the origin of gouge in the Main Fault: (i) "authigenic generation" consisting of fluid-mediated removal of calcite from the deforming OPA during shearing and (ii) "clay smear" consisting of mechanical smearing of calcite-poor (yet to be identified) source layers into the fault zone. Based on our data we prefer the first or a combination of both, but more work is needed to resolve this.Microstructures indicate a range of deformation mechanisms including solution-precipitation processes and a gouge that is weaker than the OPA because of the lower fraction of hard grains. For gouge, we infer a more ratedependent frictional rheology than suggested from laboratory experiments on the undeformed OPA.
