Drilling permits
From the Railroad Commission's drilling permit master — the application record, not a record of drilling. A permit is an application the Commission filed and numbered; the spud date is the only field here that says a hole was started. This file carries no approval status, so none is shown.

What the lease produced
Texas reports oil and gas by lease, never by wellbore, so this is the whole lease. Values are volume multiplied by the published monthly price, the same arithmetic the lease page shows in full.
Hydraulic fracturing
Disclosed to FracFocus, the registry Texas designates by statute (Natural Resources Code §91.851; 16 TAC §3.29). FracFocus is run by the Ground Water Protection Council and the Interstate Oil and Gas Compact Commission, not by a state agency — but the filing itself is required by Texas rule.
