UTCHEM General Information

UTCHEM, the University of Texas Chemical Compositional Simulator (copyright owned by The University of Texas at Austin), is a three-dimensional, multiphase, multicomponent, compositional, variable temperature, finite-difference numerical simulator. The code can run on a variety of Unix workstations and Windows PCs. The U.S. Army Engineer Research and Development Center (ERDC) at the Waterways Experiment Station, Vicksburg, through the Strategic Environmental Research and Development Program (SERDP), and previously EPA and the state of Texas Advanced Technology Program sponsored the development of UTCHEM for groundwater applications such as:

  • Infiltration of NAPL in both saturated and unsaturated zones
  • Partitioning interwell tracer tests (PITTs) in both saturated and unsaturated zones
  • Remediation using surfactants (SEAR) and/or polymers, surfactant foam, or cosolvents
  • Bioremediation


The Department of Energy's National Petroleum Technology Office and industrial affiliates sponsor the development of UTCHEM for oil field applications such as:

  • Tracer tests to characterize both single and dual porosity oil reservoirs
  • Surfactant EOR including the use of polymers and foam
  • Polymer flooding for EOR
  • High pH chemical flooding for EOR
  • Microbial EOR
  • Profile control of oil wells with polymer gels
  • Modeling formation damage of oil wells
