Carla #2 (API 42-461-34912) is a well in Upton County operated by Cog Operating LLC, completed August 21, 2009 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued September 28, 2005, permitted to 10,550 ft.

It was permitted by Henry Petroleum LP and has since transferred to Cog Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.

Its lease has reported 266K barrels of oil and 649K mcf of gas since April 2006, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
