Sorry guys, didn't mean to put your cerebrals in a bind. Just that I heard a "rumor" that the Messenger well has 7000 lbs of pressure (same as Westdale) someone told me, and was curious what it meant. Sorry I don't have the vocabulary for O&G conversation, just trying to learn like everyone else.
7000 "pounds per square inch'' would generally mean shut in tubing presure at the surface. Bottom hole presure would be this plus the weight of what ever was in the hole . The weight of the gas is small, but with drilling mud in the hole , the wight of the materal is very important. Say a well is 10,000 deep and you have 15 Pound mud in the hole, the bottom hole presure will then be 15x10,000x.052 or 7,800 psi. Hope this helps..
DD, bottom hole pressure would be the shut-in surface pressure plus the weight of the natural gas. Assuming the 7000 psi is shut-in surface pressure, the bottom hole pressure would be ~ 8500 psi for a 10,000' depth.
As exciting as this is, we know that we have a responsibility to do this thing correctly. After all, we want the farm to remain a place where the family can gather for another 80 years and beyond. This site was born out of these desires. Before we started this site, googling "shale' brought up little information. Certainly nothing that was useful as we negotiated a lease. Read More
