PDQ LEASE REPORTS · FIRST AUG 2008 · LAST VOLUME JAN 2026 · STATEWIDE DATA THROUGH APR 2026
Gas by month
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.
Last 12 months 36 · prior 12 41(-12%)
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
Each run of months one operator filed the production report, oldest first.
