Rusk County · East Texas field · Vertical
Mason Fuller #2 (API 42-401-31678) is a well in Rusk County operated by Southlake Operating LLC, completed April 6, 1984.
The RRC has issued one drilling permit, issued July 11, 1983, permitted to 3,800 ft.
It was permitted by Noe, T. C. Oil Acct. and has since transferred to Southlake Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Pecan Gap.
Its lease has reported 19.2K barrels of oil and 17.9K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
