Gulley Gas Unit No. 1

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.

No oil reported in the last ten years. 2.54K bbl over the lease's record. Show every year

An Arps exponential curve fitted to the 26 reporting months of gas since the peak in Oct 2022. 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.
