Description
Compare choke diameter sizing using different critical flow correlations (Gilbert, Ros, Baxendell, Achong, Pilehvari).
Design Steps:
- Input wellhead pressure, target liquid rate, and GLR
- Calculate required choke size using each correlation
- Verify flow rate with sized choke
- Compare results across correlations
Correlation Selection:
- Gilbert: Most widely used, good starting point
- Ros: Modified Gilbert coefficients
- Baxendell: Developed from Lake Maracaibo data
- Achong: Lake Maracaibo wells, higher GLR
- Pilehvari: Based on U. of Tulsa experimental data
