BioRita Esuru Okoroafor is currently a Graduate student at the Energy Resources Engineering Department. She is interested in coupling Geomechanics with Reservoir Engineering of Enhanced Geothemal Systems.
Prior to the graduate program, she has worked with Schlumberger for over 12 years. Most of her work experience has been on the fields in the Gulf of Guinea. She has held the positions of Borehole Reservoir Engineer, Reservoir and Production Engineering Team Lead, Sales Manager, Reservoir Domain Champion and Real Time Productivity Steering Product Analyst.
Her technical roles resulted in extensive experience on Formation Testing, Petrophysics, Well Testing, Production Logging, Well Integrity and Single Well Simulation and Production Forecasting, from which she has ten technical papers published, one granted patent and one patent application.
Her non-technical roles gave her an opportunity to develop skills in leadership, communication, presentation and customer relationship management.
Since 2005, Rita has been an active volunteer with the Society of Petroleum Engineers (SPE), holding leadership and committee member positions, locally, regionally and internationally.
Her other interest includes writing and she is the author of the fiction novels "Against The Perfect Will" and "Morning Does Come".

My students and I work to understand the physical mechanisms that control flow of multiphase, multicomponent fluids in the subsurface, using a combination of experiments and theory. The theory part includes numerical simulation of flow in heterogeneous porous rocks and coalbeds, often using streamline approaches, and it also involves solving by analytical methods the differential equations that describe the interactions of complex phase equilibrium and flow (porous rocks containing more than one flowing phase can sometimes act like a chromatograph, separating components as they flow). The experiments are used to test how well the models describe reality. Applications of this work range from enhanced oil and gas recovery to geologic storage of carbon dioxide (to reduce greenhouse gas emissions) to the transport of contaminants in aquifers.
I teach a courses for graduate students on the mathematics of multiphase, multicomponent flow in porous media and on the thermodynamics of phase behavior. I also teach an undergraduate course on energy for freshmen.
