I see. So there isn't really some formula or method that would make you say "yes there is water in the line". All you can really do is crunch the theoretical dP you should be experiencing in the given system and compare that to what is reality and then draw some reasonable conclusions as to...
We're relatively small, so they have time worry about everything. It's a running theme, but it's better than not caring.
So the very low pipe efficiency of ~3% is what led you to say that there is definitely water in the line? Is the 80% a general rule of thumb?
Thank you David, you've been a tremendous help.
I'm not sure if the 5 psi difference is a break even point or not...I'm not privy to the economics of the pipeline. There was at one point in time a 10 psi difference, so I think they are more concerned with why there is that difference. The...
I agree with you about the P and q, it makes much more sense the way you described it. It's very possible that there was some misunderstanding when they explained it to me.
Would two phase flow give a more accurate calculation? In theory, there should only be NG flowing through the line, we...
I don't have MathCAD, I'll just go back and do Colebrook by hand.
The well is producing both oil and gas (shallow well, ~2000'). As I understand it, the gas pressure and oil production are directly related. So if the pressure goes down the oil production goes down as well. That's why they...
It was about 40-45 *F when I went out and took the pressure readings. I don't know exactly when they took the previous readings and don't know what the weather was. It's very possible that it was much warmer. It's been near freezing one day and mid 60's the next around here lately. I just...
I haven't done any fluids in a while so bear with me, and I apologize for the length of my post.
We have an NG pipeline that has an upstream pressure of 50 psig and a downstream pressure at the sales line of 45 psig (has been as low as 40 psig). The flow rate had been around 80 MCFD but as of...
