Dimmit County · Hugh Fitzsimons (Olmos) field · Vertical
San Pedro Ranch #4-15 (API 42-127-31748) is a plugged well in Dimmit County, plugged May 23, 1996, last operated by Prime Operating Company.
The RRC has issued 2 drilling permits between 1978 and 1982, permitted to 4,000 ft.
It was permitted by Galaxy Oil Company and has since transferred to Prime Operating Company on the wellbore schedule.
Its 2 leases have reported 802K barrels of oil and 9.36M mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 180 wells, so these are lease totals, not this well alone.
