I’ve been monitoring a few counties in Oklahoma and have run across well names coded with MH often. Today I see one coded with WH. I’ve unconfidently understood MH to mean horizontally producing multiple depths in the same hole - and would like very much to be corrected with a better understanding if needed. Even if that’s what it means I still have questions too. I haven’t got a clue what WH would mean. Anybody care to teach a novice a little more about this coding on OCC?
Here are today’s examples. Looking like they’re on the same Section to me.
MH - [http://imaging.occeweb.com/OG/Well%20Records/1DD0988F.pdf](http://imaging.occeweb.com/OG/Well%20Records/1DD0988F.pdf)
WH - [http://imaging.occeweb.com/OG/Well%20Records/1DD09890.pdf](http://imaging.occeweb.com/OG/Well%20Records/1DD09890.pdf)
Thanx

Maybe it’s a Devon code, don’t recall anyone else using those.
