"Unconventional challenges in pore scale modeling of porous media"
Hydrocarbon exploration and CO2sequestration increasingly require understanding of tight and deep formations (tight gas sands, shale, salt) and their flow, storage and sealing capacity. Pore scale modeling of porous media (traditionally on the length scale of pores in between sand grains), has thus shifted to multiscale systems spanning nanometer to millimeter scale. These complex void spaces are notorious for dictating macroscopic fluid flow capacity or trapping fluids due to dominant capillary forces. I will exemplify how high resolution imaging techniques and image-based numerical modeling are used in complementary way to address multiscale, unconventional pore modeling challenges. In particular, I present a brand new level set method that for the first time allows computation of anisotropic crystal/brine networks in textural equilibrium and consequently investigation of salt permeability under high pressure/temperature conditions.
Maša Prodanović has been an assistant professor at the Department of Petroleum and Geosystems Engineering, The University of Texas at Austin since August 2010. She holds a Bachelor of Science in Applied Mathematics from the University of Zagreb, Croatia and a PhD in Computational Applied Mathematics from Stony Brook University, New York, USA. She has held a Research Associate position in the Center for Petroleum and Geosystems Engineering (UT Austin) 2007-2010, and prestigious J. T. Oden Postodoctoral Fellowship at the Institute of Computational Engineering and Sciences 2005-2007, prior to her current post. Her research interests include multiphase flow and image‐based porous media characterization especially applied to microfractured media and tight media, pore network models, shale gas flow, particulate flow and formation damage, sediment mechanics, fracturing and ferrohydrodynamics.
