Decline curve
None shown. Petrora fits an Arps curve only when the last ten years of gas reports follow one decline closely enough to project (R² of 0.7 or better over at least a year since the peak). This lease's recent history does not, so a projection would be a guess dressed as a number.
Who reported it
