Thesis Abstract

Ongoing discoveries of hydrocarbons within the Levantine Basin have confirmed its petroleum potential. The Aphrodite (4.3 tcf) and the Calypso gas discoveries provided concrete evidence of the presence of source rocks.  The Nile Delta, which is about 6,690 km long, empties all its sediments into the Eastern Mediterranean, as it is the origin of the organic matter that results in the biogenic gas discovered. Analytical data from the literature together with the results from 1-D and 2-D modelling, as well as, the analytical investigation, presented in this thesis provides a conceptual framework for future exploration plays.  The timing of transformation, migration, and accumulation of gaseous hydrocarbons and the evaporitic sequence (seal) were favourable for the preservation and entrapment of biogenic gas. The comparative analytical investigation carried out in this thesis provides more confidence in the model results and revealed that the volume of generated biogenic gas can be affected by temperature, pressure, gas compressibility, and the hydrogen index. Results obtained from the model also indicate that there was over-pressurization as a result of the evaporite layer measuring about 2,000 m thick.
