Webb County · San Idelfonso (Lobo) field · Producing · Vertical
Cog Malakoff-Peterson A #3 (API 42-479-35026) is a well in Webb County operated by Columbus Energy LLC, completed July 7, 1990 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued April 17, 1990, permitted to 6,865 ft.
It was permitted by Columbus Energy Corp. and has since transferred to Columbus Energy LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Lobo 1, Lobo 6.
Its 2 leases have reported 6.23K barrels of oil and 2.79M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
