Energy Efficiency Metrics

Energy Efficiency Metrics
Metric Definition Unit
SEC (Specific Energy Consumption) Total energy / Production kWh/boe or MJ/Sm³
EEI (Energy Efficiency Index) Actual SEC / Reference SEC Dimensionless
Flare intensity Flared gas / Production Sm³/boe
Compression efficiency Isentropic work / Actual work %

Usage Example

EnergyEfficiencyCalculator calc = new EnergyEfficiencyCalculator();
calc.setOilProduction(10000, "bbl/day");
calc.setGasProduction(2.0, "MMSm3/day");
calc.setCompressorPower(5000, "kW");
calc.setCompressorEfficiency(0.75);
calc.setPumpPower(1000, "kW");
calc.setHeatingDuty(8000, "kW");
calc.setFlaringRate(0.05, "MMSm3/day");

EnergyReport report = calc.calculate();

System.out.println("SEC: " + report.getSpecificEnergyConsumption() + " kWh/boe");
System.out.println("EEI: " + report.getEnergyEfficiencyIndex());
System.out.println("Potential savings: " + report.getPotentialSavings() + " MW");
