Gas-well gas plus casinghead gas, mcf. On an oil lease all gas is reported as casinghead. The latest months are revised upward as late reports arrive.

Barrels reported on Form PR for the whole lease. The latest months are revised upward as late reports arrive.

An Arps hyperbolic curve fitted to the 23 reporting months of gas since the peak in Jun 2024. The dashed line below is that curve, drawn over the months it was fitted to and then 24 months past the last report; where it parts from the columns is where the model stops describing the lease. It describes the trend of past reports. It does not know about recompletions, shut-ins, or new wells, and it is shown only when the lease reported within the last year and the curve explains most of the history.
