Class CMGEOSExporter

java.lang.Object
neqsim.blackoil.io.CMGEOSExporter
public final class CMGEOSExporter extends Object
CMG (Computer Modelling Group) reservoir simulator EOS/PVT exporter.

Exports NeqSim compositional fluids or Black-Oil PVT tables to CMG-compatible format for use in IMEX, GEM, and STARS simulators.

Supported CMG Keywords

  • PVTG - Gas PVT table
  • PVTO - Oil PVT table
  • PVTW - Water PVT properties
  • DENSITY - Stock tank densities
  • BWI/CW/VW - Water properties

Usage Example


SystemInterface fluid = new SystemSrkEos(373.15, 200.0);
fluid.addComponent("methane", 0.7);
fluid.addComponent("n-heptane", 0.3);
fluid.setMixingRule("classic");

CMGEOSExporter.toFile(fluid, Path.of("PVT.DAT"), CMGEOSExporter.Simulator.IMEX);
