Abstract:
This thesis is split into the two scientific topics studied; overpressure development in deep basins and present-day and future gas hydrate dissociation in the Arctic. Locating and quantifying overpressure is essential to understand basin evolution and hydrocarbon migration in deep basins and thickly sedimented continental margins. The first part of this thesis develops two new methods, including an inverse model, to impose seismic and geological constraints on models of overpressure generated by the disequilibrium compaction and aquathermal expansion mechanisms. The results provide greater understanding of a low velocity zone (LVZ), inferred from wide-angle seismic data, in the centre of the Eastern Black Sea Basin (EBSB). The application of both methods in the study area indicate that the LVZ located within the Maikop formation, at ~3500-6500 m depth below the seabed (mbsf), is linked to overpressure generated, mainly, by disequilibrium compaction.
