If there’s one thing I know about O and G it’s take what the logical cost for valves/piping and multiply it by 5-10. When we would replace a gate valve on a wellhead it cost around 8k, or a ball valve in a process facility, just a 2 inch face with a pressure actuator it cost 5k, the 18” process valves we used were 25k apiece. That facility is gonna run closer to a million to build.
fink, I am going to work on having all of your DD put into the intro. More importantly, I am going to try to get all of this into one post so it will be the stickie of the century!
