Dr Hector Marin Moreno
My research interests are on the areas of computational geoscience, rock physics modelling, and offshore geotechnics. I use modelling techniques to understand changes in the electric, acoustic, thermal, mechanical and fluid flow properties of marine sediments to anthropogenic and natural perturbations. Most of my work until date has been focused on (i) developing an inversion model for determining sediment overpressure and its controlling physical parameters by combining seismic velocity information with a physical model of sediment compaction; (ii) numerical modelling of warming-induced gas hydrate dissociation in Polar areas during the 21st century; and (iii) developing a comprehensive rock-physics model to calculate frequency dependent and causal P and S wave velocity and attenuation of an effective porous medium composed of solid mineral grains, gas hydrate, gas, and water. The ultimate aim of the latter, is to improve our theoretical insights on seismic velocity and attenuation of gas hydrate bearing sediments with different hydrate morphologies and hydrate and/or gas saturations. On-going work includes developing a soil mechanics constitutive model for gas hydrate bearing sediments to reproduce their elasto-plastic response under different thermal and structural loading scenarios acting simultaneously, and reactive transport modelling of chimney structures in the North Sea above potential CO2 storage reservoirs.
