King Ranch Alazan #307
Kleberg County · Alazan North (Frio Cons.) field · Vertical
King Ranch Alazan #307 (API 42-273-30542) is a plugged well in Kleberg County, plugged June 17, 2008, last operated by Exxon Mobil Corporation.
The RRC has issued 2 drilling permits in 1994, permitted to 7,616 ft.
It was permitted by Exxon Corp. and has since transferred to Exxon Mobil Corporation on the wellbore schedule.
Its 3 leases have reported 256K barrels of oil and 509K mcf of gas since the record begins in January 1993, with no volume in the three years through August 2026. The leases carry 130 wells, so these are lease totals, not this well alone.
