King Ranch Alazan #310 (API 42-273-31282) is a plugged well in Kleberg County, plugged October 4, 2013, last operated by Eog Resources Inc..

The RRC has issued 5 drilling permits (amended once) between 1978 and 1991, permitted to 10,500 ft.

It was permitted by Exxon Corp. and has since transferred to Eog Resources Inc. on the wellbore schedule.

Its 5 leases have reported 931K barrels of oil and 1.32M mcf of gas since January 1993, last reporting in March 2025. The leases carry 55 wells, so these are lease totals, not this well alone.
