Kleberg County · Wildcat field  · Vertical

King Ranch Alazan #321 (API 42-273-31313) is a plugged well in Kleberg County, plugged October 4, 2004, last operated by Exxon Mobil Corporation.

The RRC has issued 7 drilling permits between 1978 and 1998, permitted to 6,600 ft.

It was permitted by Exxon Corp. and has since transferred to Exxon Mobil Corporation on the wellbore schedule.

Its 7 leases have reported 16.7K barrels of oil and 96.2K mcf of gas since January 1993, last reporting in March 2008. The leases carry 8 wells, so these are lease totals, not this well alone.
