Palo Pinto County · Mallory (Strawn) field · Producing · Vertical
Robinson Ranch #4 (API 42-363-34970) is a well in Palo Pinto County operated by Tarpon Oil & Gas CO., completed January 1, 2001 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 6, 2000, permitted to 1,850 ft.
It was permitted by Tarpon Oil Company and has since transferred to Tarpon Oil & Gas CO. on the wellbore schedule.
Completion filings report one formation top, including Strawn.
Its lease has reported 477K barrels of oil and 790K mcf of gas since January 2000, last reporting in July 2026. The lease carries 29 wells, so these are lease totals, not this well alone.
