A method of measuring a dry gas flow from hydrocarbon wells. The hydrocarbon wells produce a stream which contains liquids and natural gas. The method comprises providing an differential flow measurement device (orifice) located at a well site containing the hydrocarbon wells. The method further includes testing the stream for gas composition and physical characteristics. Additionally, the method comprises measuring a static temperature (T) of the stream, measuring a static pressure (Ps), and measuring a pressure differential (dP) in the differential flow measurement device (orifice). The method includes computing the liquid-gas ratio (LGR) of the stream, computing the wet gas flow rate (Qw) of the stream, computing a first dry gas flow rate (Qd1) and a second dry gas flow rate and utilizing a iterative process to correct and obtain the dry gas flow rate. The data may be transmitted to another location.
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:
The method of claim further comprising:
A method of measuring the dry gas flow from a stream, said stream containing natural gas and liquids from hydrocarbon wells, the method comprising:
The method of claim 11 wherein the step of correcting the wet flow rate to the dry flow rate includes subtracting Qd1 from Qd2 to obtain a first delta factor;
