Flow Control
(OP)
Help. I need some info on wellhead and surface flow systems. I hear terms of 'tubing flow valve' and 'backpressure valve' thrown around. First off would those be the same thing. Are they standard on most gas wells? What kind of configuration should you have if you need to bleed down a well to pipeline pressure but do not want a large reservoir drawdown pressure? Any advice on pdfs or book on gas flow systems would be great!!

The MOV may also be activated by instruments that monitor contaminates or BTU content.
This is a typical installation, each pipeline may provide other services or requirements. Just work with them.

It's hard to reach an errosional velocity and keep a pressure drop per 100 under 5 psi.

Sorry my knowledge is still limited on the functionality of the wellhead; You question why would you choke the well back? If a well is not choked then what is controlling the backpressure on the perfs? Too much drawdown is not gonna be good for the reservoir.

The alst thing you want is to open the choke all the way and suddenly get water coning, especially if it's a stable cone (that won't go away if you then choke the well back!)
