Decline curve

A MODEL FITTED TO THE REPORTS, NOT A REPORT

An Arps exponential curve fitted to the 48 reporting months of oil since the peak in May 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.
