Carlos studied Chemical Engineering and Reservoir Engineering in Argentina before joining the National Research Council (CONICET). In 1990 he moved to the UK to study at Imperial College London, where he was awarded a PhD. He spent 12 years in the Petroleum Engineering Group at Imperial College, mostly working in projects sponsored by oil industry, EPSRC, and EU, and managed the Petroleum Engineering Research Laboratory for five years. In 2006 joined Rock Deformation Research Ltd to help set up and develop the Sorby Multiphase Flow Laboratory (now part of the Wolfson Lab). During 2012 he joined the School of Earth and Environment.

Carlos has been actively involved in research for over 30 years and has written over one hundred and fifty papers. He is currently working in three oil industry sponsored consortiums:

  • Petrophysical Properties of Tight Gas Sandstones (PETGAS);
  • Fault Rock Petrophysics (FAULTPROP);
  • Impact of Faults in Carbonates (CARBFAULT)

Research Interests

Carlos research interest are in rock-fluid interactions and displacement processes in low permeability rocks including: Basic aspects of the displacement processes, relative permeabilities, capillary pressures, electrical resistivity, NMR petrophysics.

Other areas of interest are:

  • Rocks and fluids interactions and flow, wetting and spreading and its influence on petrophysical properties and fundamental reservoir engineering.
  • 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: Miscible, low interfacial and 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.
