Going into the hole you add pipe, coming out of the hole you take away pipe..
It is snowing but the drillers don’t stop. When you are drilling a mile down you don’t leave the hole open long. The Earth doesn’t tolerate straws dipped into its reservoir and can close its teeth with a snap.
You drill, test, lay pipe and produce, or plug the hole.
Trying to hit a target you can’t see and can’t know the size of , covered by roller coaster layers of Earth 4000 plus feet down, is tough.
A fair number of wells are busts.
A few are bonanzas.
Every project looks good before you drill it or we wouldn’t be out here freezing our tails off.
