New summer oil lecture series

The Faculty of Engineering and Applied Science kicked off a new summer oil lecture series on Tuesday, Aug. 14 with a pair of presentations.

Dr. Marios loannidis started the series with a morning presentation that summarized the current understanding of the saturated water injection (SWI) process. He explained that the gas phase (developed in situ) moves in the form of disconnected gas clusters, and that gas cluster dynamics driven by inter-phase mass transfer is shown to be a unique feature of SWI. This discovery invites researchers to rethink a number of processes requiring the introduction of a gas phase in porous media, which could benefit from SWI.

Dr. Ioannidis is a professor of chemical engineering at the University of Waterloo. He holds a PhD in chemical engineering from the University of Waterloo and a BASc from the University of Patras, Greece.

In the afternoon, Dr. Felix Kwok explained how in most oil reservoir simulators, fluid flow is modeled by a system of nonlinear partial differential equations (PDEs) that exhibit both hyperbolic and parabolic character. He presented methods for improving the efficiency of the nonlinear solver by exploiting flow direction information. Dr. Kwok also showed how one can reduce the effective size of the nonlinear system by reordering the variables and equations from upstream to downstream, then eliminating the saturation variables successively.

Dr. Kwok has a B.Sc. in joint honors math and computer science, and a PhD from Stanford in the scientific computing/computational math program. He is a research scientist in the math department at the University of Geneva, Switzerland.

Both lectures were attended by faculty, staff and students from across Memorial University.
