Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Operator on the lease's P-4
Each operator named on the P-4 filings for this well's lease (a gas well is its own lease), from the date its filing took effect. The P-4 is filed by lease, so a date before the well was drilled is the lease's.
