All Implemented Interfaces:
Serializable
public class ArtificialLiftScreener extends Object implements Serializable
Artificial lift screening and selection tool.

This class provides comprehensive artificial lift method comparison and selection based on reservoir and well conditions. Supported methods include:

  • Natural Flow: Baseline case with no artificial lift
  • Gas Lift: Continuous or intermittent gas injection
  • ESP (Electrical Submersible Pump): Downhole electric pump
  • Rod Pump: Sucker rod pump (beam pump)
  • PCP (Progressive Cavity Pump): For viscous fluids
  • Jet Pump: Hydraulic power fluid system

Screening Methodology

The screening process follows industry best practices:

  1. Technical Screening: Eliminates infeasible methods based on operating envelope
  2. Performance Calculation: Estimates production rate for each method
  3. Economic Ranking: Ranks methods by NPV or cost per barrel lifted
  4. Risk Assessment: Considers reliability and operational complexity

Operating Envelope Limits

Operating Envelope Limits by Method
Method Max Depth (m) Max Rate (Sm3/d) Max GOR Max Temp (°C) Max Visc (cP)
Gas Lift 5000 5000 5000 200 50
ESP 4500 15000 500 180 200
Rod Pump 3000 500 200 150 1000
PCP 2500 800 100 130 10000
Jet Pump 5000 2000 1000 200 50

Usage Example

ArtificialLiftScreener screener = new ArtificialLiftScreener();
screener.setReservoirPressure(250.0, "bara");
screener.setReservoirTemperature(90.0, "C");
screener.setWellheadPressure(15.0, "bara");
screener.setWellDepth(2800.0, "m");
screener.setProductivityIndex(8.0);
screener.setOilGravity(32.0, "API");
screener.setWaterCut(0.40);
screener.setFormationGOR(150.0);
screener.setOilViscosity(5.0, "cP");
screener.setGasLiftAvailable(true);
screener.setElectricityAvailable(true);

ScreeningResult result = screener.screen();

System.out.println("Recommended: " + result.getRecommendedMethod());
for (MethodResult method : result.getAllMethods()) {
  System.out.println(method);
