Masterson A #8409AP (API 42-375-30843) is a permitted well in Potter County filed by Coastal Oil & Gas Corporation; no completion report is on file yet.
The RRC has issued one drilling permit, issued April 29, 1981, permitted to 2,200 ft.
It was permitted by Coastal Oil & Gas Corporation and has since transferred to Snw Operating Company on the wellbore schedule.
Its lease has reported 98.5K barrels of oil and 250K mcf of gas since January 1993, last reporting in July 2026. The lease carries 25 wells, so these are lease totals, not this well alone.
