Deviated Well VLP Analysis

Analyze vertical lift performance in deviated and inclined wells using correlations that properly account for inclination angle. Four correlations support non-vertical wells:

Inclination-Supporting Correlations:

• Beggs & Brill (1973): Most widely used, general-purpose for any inclination
• Gray (1974): Originally for gas wells, supports inclination
• Hasan-Kabir (1988): Mechanistic model, excellent for deviated wells and annular geometry
• Mukherjee-Brill (1985): Specifically developed to improve Beggs-Brill for inclined flow

Note: Vertical-only correlations (Hagedorn-Brown, Ansari, Orkiszewski, Duns-Ros, Aziz, Poettmann-Carpenter) should not be used for wells with significant deviation.
