San Pedro Ranch #305
Dimmit County · Hugh Fitzsimons (Olmos) field · Vertical
San Pedro Ranch #305 (API 42-127-31997) is a plugged well in Dimmit County, plugged June 10, 2013, last operated by Prime Operating Company.
The RRC has issued 2 drilling permits between 1980 and 1983, permitted to 4,000 ft.
It was permitted by Galaxy Oil Company and has since transferred to Prime Operating Company on the wellbore schedule.
Completion filings report 4 formation tops, including Escondido, Taylor, Olmos, San Miguel.
Its 2 leases have reported 85.8K barrels of oil and 425K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 19 wells, so these are lease totals, not this well alone.
