King Ranch Alazan #315 (API 42-273-31278) is a plugged well in Kleberg County, plugged August 7, 2008, last operated by Exxon Mobil Corporation.

The RRC has issued 6 drilling permits between 1978 and 1994, permitted to 8,300 ft.

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

Its 4 leases have reported 256K barrels of oil and 1.63M mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 131 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
