Biography

Abdullah Cihan is a Staff Scientist in the Energy Geosciences Division at Lawrence Berkeley National Laboratory. His general research area is transport phenomena in subsurface environments, with emphasis on theoretical description of flow and transport processes affected by heterogeneities across scales. His research applications have been related to geologic carbon sequestration, gas/oil production from unconventional reservoirs, evaporation from soil, land-mine detection in soil and groundwater remediation.

Code Development

  • Brine flow simulator, Mix3d_H2O_NaCl (The Finite Volume Method-based numerical solution of water and NaCl mixing in porous media). This code has been used for NRAP project studies for the DOE-BEST project.
  • MDPD, Many-body dissipative particle dynamics simulator. This is a computer code solving Newton’s equations for fluid particles/molecules at pore-scale. The code has been used for the project ‘Understanding Water Controls on Shale Gas Mobilization into Fractures’ funded by NETL.
  • CDE, Constrained differential evolution algorithm for optimization. The code has been used for CCSMR, NRAP and DOE-BEST projects.
  • TP3D_HYST, Hysteretic two-phase flow modeling code. The code, including new hysteretic capillary pressure-saturation-relative permeability models has been used for multiple CO2 storage projects.
  • ASLMA, Analytical Solution for leakage in multilayered aquifers. Its development was funded by EPA. The code has been used in multiple projects.
  • MIP, Macroscopic invasion percolation simulator. The code was used for the DOE project in partnership with Princeton University.
  • MIPDLA- Numerical solution of two-phase flow in heterogeneous systems combining diffusion-limited aggregation and macroscopic invasion percolation methods. The code was used for investigations during the DOE project in partnership with Princeton University.
  • IP3D- Computer code simulating quasi-steady multiphase flow processes at pore-network systems. The code was used for upscaling studies in the DOE project in partnership with CSM and NRAP projects.
  • UPSCALE2PF- Upscaling two-phase flow parameters for large-scale simulations using subgrid scale measurements. Software developed for upscaling two-phase flow properties in heterogeneous large-scale reservoirs using invasion percolation method, analytical methods and numerical solution of flow equations. Funded through 'NRAP, National Risk Assessment Partnership' project by DOE-FE.
