Description
Compare pressure drop predictions from all ten industry-standard multiphase flow correlations. Understanding correlation differences helps engineers select the most appropriate method for specific well conditions.
Correlations:
- Beggs & Brill (1973): General-purpose, any inclination, most widely used
- Gray (1974): Best for gas wells with liquid loading
- Hagedorn & Brown (1965): Near-vertical oil wells, industry standard
- Ansari (1994): Mechanistic TUFFP model, vertical wells
- Hasan-Kabir (1988): Mechanistic, deviated wells and annular geometry
- Mukherjee-Brill (1985): Improvement over Beggs-Brill for inclined wells
- Orkiszewski (1967): Composite vertical well correlation
- Duns & Ros (1963): High GOR gas wells
- Aziz (1972): Drift-flux model for vertical wells
- Poettmann-Carpenter (1952): Historical no-slip method, high-rate dispersed flow
