Kleberg County · Borregos (Consolidated Gas) field · Vertical

King Ranch Borregos #543 (API 42-273-31215) is a plugged well in Kleberg County, plugged February 24, 2012, last operated by Exxon Mobil Corporation.

The RRC has issued 3 drilling permits between 1978 and 1980, permitted to 7,500 ft.

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

Its 2 leases have reported 550K barrels of oil and 3.71M mcf of gas since the record begins in January 1993, last reporting volume in February 2024. The leases carry 198 wells, so these are lease totals, not this well alone.
