King Ranch Alazan #329
Kleberg County · Alazan (Frio Cons.) field · Vertical
King Ranch Alazan #329 (API 42-273-31335) is a plugged well in Kleberg County, plugged June 28, 2011, last operated by Eog Resources Inc..
The RRC has issued 3 drilling permits between 1978 and 1983, permitted to 8,000 ft.
It was permitted by Exxon Corp. and has since transferred to Eog Resources Inc. on the wellbore schedule.
Its 2 leases have reported 925K barrels of oil and 1.32M mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 52 wells, so these are lease totals, not this well alone.
