Starr County · Bob West (L-5-10) field · Producing · Directional

Guerra Gas Unit A #23 (API 42-427-32917) is a well in Starr County operated by Merit Energy Company, completed August 4, 2005 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued August 26, 1996, permitted to 12,270 ft.

It was permitted by Coastal Oil & Gas Corporation and has since transferred to Merit Energy Company on the wellbore schedule.

Its 3 leases have reported 2.85M mcf of gas since November 1996, last reporting volume in April 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
