Class ReservoirCouplingExporter

java.lang.Object
neqsim.process.fielddevelopment.reservoir.ReservoirCouplingExporter
All Implemented Interfaces:
Serializable
public class ReservoirCouplingExporter extends Object implements Serializable
Exports time-series data for reservoir simulator coupling (E300/ECLIPSE).

Generates VFP tables, separator efficiency curves, and schedule keywords for coupling NeqSim process models with reservoir simulators. Supports both Eclipse 100 and E300 (compositional) formats.

Export Capabilities

  • VFP Tables: Vertical flow performance for wells (VFPPROD/VFPINJ)
  • Separator Efficiency: Oil/gas/water split ratios vs conditions
  • Compression Curves: Power vs rate and suction pressure
  • Network Deliverability: Platform capacity constraints
  • Schedule Keywords: Time-varying constraints

Example Usage

// Create exporter
ReservoirCouplingExporter exporter = new ReservoirCouplingExporter(processSystem);

// Configure VFP table generation
exporter.setWellheadPressureRange(20.0, 100.0, 9); // 20-100 bara, 9 points
exporter.setGasRateRange(0.1e6, 10.0e6, 10); // 0.1-10 MSm3/d
exporter.setWaterCutRange(0.0, 0.95, 6); // 0-95% water cut

// Generate VFP tables
exporter.generateVfpProd("WELL-1", wellStream, 1);

// Export to file
exporter.exportToFile("vfp_tables.inc");

// Or get as string for E300 INCLUDE
String vfpKeywords = exporter.getEclipseKeywords();
