Question I have a gas well and would like to know how much the out put is to check if the oil comp is right.I,ve got a 7" well head with a 2" line going through a .250 plate (orf),with 130 psi well pres,and 18" of water on my 7/24 meter.Is there somewhere that has a scale that i could in put the numbers to get the cubic foot numbers? Thank You robert
Answer Robert
Based on what you have given, that is an orifice meter. This orifice meter has a 2" line (I used a 2.067" ID of the pipe) with an orifice plate which has a 0.25" bore. A line pressure of 130 PSIG and a pressure differential of 18" of water. Based on this I assumed a few things like flange taps, temperature 60 degrees, plus a few others that shouldn't make a lot of difference if you just want something to check the numbers given to you. Based on the above here's a formula you can use to calculate the gas flow.
Gas Flow in Cubic Ft per Hr = 192 X the square root of the inches of water value
Your flow as given = 192 x the square root of 18 = 192 x 4.2 = 800 cubic feet per hour
or about 20 MCF per day. If the number they report to you is a lot different get back to me and I'll try to find out why the difference. I'd also be interested in what the company is paying for well head gas in your area, and where do you live.
Hope this helps
