Abstract:
1. A method of measuring a dry gas flow from hydrocarbon wells, said hydrocarbon wells producing liquids and natural gas so that a stream is produced, the method comprising: (a) providing an orifice device, said orifice device having an elliptical throat, and wherein said orifice device is located at a well site containing the hydrocarbon wells; (b) testing the stream for gas composition and physical characteristics; (c) measuring a flowing temperature of the stream; (d) measuring a flowing pressure; (e) measuring a pressure differential in said orifice device; (f) computing the liquid to gas ratio (LGR) of the stream; (g) computing the wet gas flow rate of the stream; (h) computing a first dry gas flow rate (Qd (i) computing a second dry gas flow rate (Qd (j) correcting the first dry gas flow rate (Qd
