Class EconomicsEstimator.EconomicsReport

java.lang.Object
neqsim.process.fielddevelopment.screening.EconomicsEstimator.EconomicsReport
All Implemented Interfaces:
Serializable
Enclosing class:
EconomicsEstimator
public static final class EconomicsEstimator.EconomicsReport extends Object implements Serializable
Immutable report containing economics screening results.

This class encapsulates all economic metrics from a screening estimate, including:

  • CAPEX breakdown: Facility, equipment, wells, and infrastructure costs
  • OPEX estimate: Annual operating expenditure
  • Unit costs: CAPEX and OPEX per barrel of oil equivalent
  • Accuracy range: Uncertainty bounds for the estimate

Accuracy Considerations

All estimates carry a ±40% accuracy range (AACE Class 5). The actual costs can vary significantly based on:

  • Market conditions and contractor availability
  • Detailed engineering and specifications
  • Regional cost factors
  • Project schedule and execution strategy

Thread Safety

This class is immutable and thread-safe. All collections returned by getter methods are defensive copies.

Serialization

Implements Serializable for persistence and network transfer.
