Blocker Heirs (Sun) #4 (API 42-203-30872) is a well in Harrison County operated by Petroleum Production Mgmt. Inc., completed November 18, 1981.
The RRC has issued 3 drilling permits between 1981 and 2004, permitted to 10,200 ft.
It was permitted by Gmx Resources Inc. and has since transferred to Petroleum Production Mgmt. Inc. on the wellbore schedule.
Completion filings report 7 formation tops, including BMA, Massive Anhydrite (marker), Pettit, Travis Peak.
Its 3 leases have reported 1.78K barrels of oil and 185K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
