PO.SF.CH.Gilbert.Rate(Pwh, d_choke, GLR)

Liquid flow rate using Gilbert (1954) critical flow correlation, [bbl/d]. Widely used for oil wells with gas.

PO.SF.CH.Gilbert.Pwh(Ql, d_choke, GLR)

Wellhead pressure using Gilbert (1954) critical flow correlation, [psia]. Calculates required pressure for target rate.

PO.SF.CH.Gilbert.Size(Pwh, Ql, GLR)

Choke diameter using Gilbert (1954) critical flow correlation, [inches]. Calculates required choke size for target rate.
