Choke Sizing Comparison

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
