Class FieldDevelopmentCostEstimator

java.lang.Object
neqsim.process.util.fielddevelopment.FieldDevelopmentCostEstimator
All Implemented Interfaces:
Serializable
public class FieldDevelopmentCostEstimator extends Object implements Serializable
Integrates process mechanical design and cost estimation into field development workflows.

This class provides a bridge between process equipment design and field development economics, enabling:

  • CAPEX estimation at different fidelity levels (screening, conceptual, FEED)
  • Equipment sizing linked to production capacity
  • Cost scaling with production rate
  • Mechanical design output (weights, dimensions, materials)
  • NPV-integrated cost estimation for concept comparison

Fidelity Levels

Cost Estimation Fidelity Levels
Level Accuracy Use Case Cost Basis
SCREENING ±50% Discovery, feasibility Capacity correlations
CONCEPTUAL ±30% Concept selection Equipment-type correlations
PRE_FEED ±20% Pre-FEED Sized equipment costs
FEED ±10% FEED, AFE Detailed mechanical design

Integration with FieldProductionScheduler

// Create production scheduler
FieldProductionScheduler scheduler = new FieldProductionScheduler("Offshore Field");
scheduler.addReservoir(reservoir);
scheduler.setFacility(facility);
scheduler.setPlateauRate(10.0, "MSm3/day");

// Create cost estimator linked to facility
FieldDevelopmentCostEstimator costEstimator = new FieldDevelopmentCostEstimator(facility);
costEstimator.setFidelityLevel(FidelityLevel.CONCEPTUAL);
costEstimator.setLocationFactor(1.3); // Norwegian Sea

// Run mechanical design and cost estimation
FieldDevelopmentCostReport report = costEstimator.estimateDevelopmentCosts();

System.out.println("Total CAPEX: $" + report.getTotalCapex() / 1e6 + " M");
System.out.println("Facilities weight: " + report.getTotalWeight() / 1000 + " tonnes");
System.out.println("Installation man-hours: " + report.getTotalManHours());

// Use for NPV calculation
scheduler.setCapex(report.getTotalCapex() / 1e6, 2025);
ProductionSchedule schedule = scheduler.generateSchedule(startDate, 20.0, 30.0);
System.out.println("NPV: $" + schedule.getNPV() / 1e6 + "M");

Concept Comparison

// Compare multiple development concepts
List<ProcessSystem> concepts = Arrays.asList(conceptA, conceptB, conceptC);
List<FieldDevelopmentCostReport> reports = costEstimator.compareConceptCosts(concepts);

for (FieldDevelopmentCostReport report : reports) {
  System.out.printf("%s: CAPEX=$%.0fM, Weight=%.0ft, Area=%.0fm2%n", report.getConceptName(),
      report.getTotalCapex() / 1e6, report.getTotalWeight() / 1000, report.getFootprintArea());
}
