SPE Japan Section was pleased to invite Dr. Russell Johns for the 2nd distinguished lecturer program (Zoom Meeting) on May 28, 2020.
Date: 10:30-12:00 JST, May 28, 2020
Topic: Compositional Simulation that is Truly Compositional
Lecturer: Dr. Russell T. Johns, The Pennsylvania State University
Russell T. Johns is the George E. Trimble Chair of Energy and Mineral Sciences at the Department of Energy and Mineral Engineering at The Pennsylvania State University. He also holds the Energi Simulation Chair in Fluid Behavior and Rock Interactions.
In this lecturer program, he provided new simulation technologies to correctly account for the compositional effects on relative permeability, capillary pressure, and grid-block flux calculations in the compositional simulation process. In the current compositional simulators, relative permeability, for example, is still based on “old thinking” related to labeling of phases as “oil, gas, and water. This labeling ("old thinking") generates discontinuities and errors in compositional processes.
In the presentation, he showed several example cases, including WAG and surfactant flooding, are given using a new type of compositional simulator with all labels removed. The relative permeability model is physically based and captures complex hysteresis effects through saturation and phase connectivity as well as changing wettability, interfacial tension, and pore morphology. The results show increased robustness, improved accuracy, faster computational times, and less instabilities when phase labeling is removed.
SPE Japan is glad to have him as one of the distinguished lecturer this year. We appreciate his informative talks and look forward to seeing the Japan section members in the next distinguished lecture program.
Thank you.
