Class EclipseEOSExporter

java.lang.Object
neqsim.blackoil.io.EclipseEOSExporter
public final class EclipseEOSExporter extends Object
Eclipse reservoir simulator EOS/PVT keyword exporter.

Exports NeqSim compositional fluids or Black-Oil PVT tables to Eclipse-compatible include files containing PVTO, PVTG, PVTW, and DENSITY keywords.

Supported Eclipse Keywords

  • PVTO - Live oil PVT table (Rs, P, Bo, viscosity)
  • PVTG - Wet gas PVT table (Rv, P, Bg, viscosity)
  • PVTW - Water PVT properties
  • DENSITY - Stock tank densities
  • PVCO - Alternative compressed oil format

Usage Example


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

EclipseEOSExporter.toFile(fluid, Path.of("PVT.INC"));
