1. Basic Data Collection
Well profile, casing, tubing, perforation depth
Fluid properties: API gravity, water cut, GOR, pressures, temperatures
Production targets and power availability
2. Production Capacity
Uses Productivity Index (PI) to estimate inflow performance
Calculates flowing bottomhole pressure (Pwf) and pump intake pressure (PIP)
3. Gas Calculations
Determines free gas volume at pump intake
Uses Standing’s correlation for solution GOR
Calculates oil and gas formation volume factors (Bo and Bg)
4. Total Dynamic Head (TDH)
Combines net well lift, tubing friction loss, and wellhead pressure head
Uses Hazen-Williams formula for friction loss
5. Pump Type Selection
Chooses pump series based on casing size and flow rate
Calculates number of stages and required brake horsepower (BHP)
6. Compound Sizing
Selects seal, motor, and evaluates gas separator need
Motor selection considers frequent starts/stops and voltage requirements
7. Cable Selection
Determines cable size, type, and length
Calculates voltage drop and power loss for cost analysis
8. Accessory Equipment
Includes motor lead extension, cable bands, protectors, check valves
Surface equipment like Variable Frequency Drive (VFD) and transformer taps
9. Final System Integration
Ensures all components are compatible and optimized for performance and cost.
