Research Interests
- Rocks and fluids properties and fundamental reservoir engineering: Rocks and fluids interactions and flow, wetting and spreading and its influence on relative permeabilities, capillary pressures, electrical resistivity and NMR response.
- Multiphase flow in porous media: Mechanisms of reservoir displacement processes with applications in waterflood, gas injection, and EOR processes. Pore-scale phenomena and scaling up. Basic aspects of critical/residual saturations, hysteresis, and heterogeneities.
- Oil and gas recovery: Basic aspects of the displacement processes in tight rocks. Miscible, low interfacial tensions, multi-contact miscible displacements. Water Alternated Gas and Depressurisaton of waterflooded reservoirs. Influence of surfactants and polymers on fluid- rock interactions, oil-gas trapping and flow. CO2 storage and enhanced coalbed methane.
