Viboras Field Gas Unit No. 1 #99
Brooks County · Viboras (Frio Cons.) field · Vertical
Viboras Field Gas Unit NO. 1 #99 (API 42-047-31058) is a plugged well in Brooks County, plugged November 28, 2006, last operated by Exxon Mobil Corporation.
The RRC has issued 5 drilling permits (amended once) between 1981 and 1998, permitted to 10,400 ft.
It was permitted by Exxon Corp. and has since transferred to Exxon Mobil Corporation on the wellbore schedule.
Its 3 leases have reported 186K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
