Enhancing the Predictive Capability of the Pore-Scale Multiphase Fluid Transport in Unconventional Reservoirs: A Molecular Dynamics Simulation Approach(PPT)

摘要

1. Developing kerogen molecular models with submerged nanopores is a complex process 2. MD simulations enable access to length scales (sub-nanometer and nanometer sized pores) which is challenging otherwise 3. Gas exists in adsorbed as well as free form - free gas is primarily recovered 4. Higher injection and/or differential pore pressures are necessary to overcome a dominant fluid-pore surface interactions and to enhance the mobility of fluids in nanometer and sub-nanometer sized kerogen pores 5. Evidence of water and methane adsorption on the pore surface
