SUMMARY:A Multiscale, Multiphysics Framework for Multiphase Fluid Flow in 
 a Complex Subsurface Environment: Application to Sustainable Enhanced Oil 
 Recovery
DESCRIPTION:Martin Andersson, Fernando Alonso Marroquin, Mohamed Gamal Rez
 k, and Safwat Abdel-Azeim (King Fahd University of Petroleum and Minerals)
 \n\nWe have developed a computational framework for seamlessly bridging mo
 lecular scale properties via the pore and core scale all the way to the fi
 eld scale for multiphase flow in porous media. \n\nWe combined thermodynam
 ic and kinetic effects on the molecular scale using density functional the
 ory, COSMO-RS thermodynamics, molecular dynamics simulations and numerical
  modelling of diffusion across a liquid-liquid interface. The combination 
 of computational techniques allowed us to identify the underlying molecula
 r scale mechanism for how a novel sustainable additive changes wettability
  in limestone reservoirs. The framework also allowed us to compare our cal
 culations directly to a large set of experimental data ranging from the mo
 lecular partitioning and interfacial tension in water-oil systems, to rock
  wettability on the pore scale.\n\nIn the second stage, the computed surfa
 ce wettability is used as key input to predict the capillary-pressure satu
 ration curve using pore morphology and percolation theory methods on the e
 xperimental pore network of the real rock. This is used to explain core sc
 ale experimental saturation profiles and improved oil recovery, and provid
 es a standard input for reservoir simulations used to assess field scale p
 roperties.\n\nDomain: Chemistry and Materials, Computational Methods and A
