Here are standard analyses that are being carried out in our Crude Oil and Natural Gas PVT (Pressure-Volume-Temperature) laboratory. These tests are performed to characterize reservoir fluid behavior and provide essential data for reservoir engineering, production forecasting, and facility design.

  1. Basic Compositional Analysis
  2. True Boiling Point (TBP) distillation
  3. Compositional analysis of separator gas and separator liquid
  4. Single-stage flash – GOR, API gravity, gas gravity
  5. Differential liberation (DL) test
  6. Constant composition expansion (CCE) / Constant mass expansion
  7. Viscosity measurement (at reservoir temperature, various pressures)
  8. Density measurement (at reservoir and separator conditions)
  9. Constant volume depletion (CVD) – Dew point pressure, liquid dropout, Z-factor, produced gas gravity
  10. Dew point pressure determination
  11. Recombination of separator samples to reservoir fluid (at correct producing GOR)
  12. Bubble point pressure determination
  13. Solution gas-oil ratio (Rs) measurement
  14. Oil formation volume factor (Bo, Bob, BoB)
  15. Gas formation volume factor (Bg)
  16. Total formation volume factor (Bt)
  17. Gas compressibility factor (Z-factor) measurement
  18. Asphaltene onset pressure (AOP) determination (light transmittance, high-pressure microscopy, filtration)
  19. Wax appearance temperature (WAT) / Wax disappearance temperature (WDT)
  20. Pour point and cloud point measurement
  21. Emulsion tightness testing
  22. Hydrate formation/dissociation studies
