WINDOWS ON THE APPROVAL DATE, AGAINST THE WINDOW BEFORE · TEXAS COUNTS EVERY PERMIT ON A WELL, OTHER STATES A WELL'S LATEST
About this data
Operator registrations from each state regulator. Permit windows are on the approval date. Active wells are the wells an operator is operator of record for today. Volumes are what the operator itself filed, so they stay with it after it sells a well; the twelve months end in the state's last reported month. Nothing is estimated.
