Colossus 44 #2 (API 42-173-37957) is a well in Glasscock County operated by Oxyrock Operating LLC, completed February 5, 2019 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 7, 2018, permitted to 12,000 ft.
It was permitted by Crownquest Operating, LLC and has since transferred to Oxyrock Operating LLC on the wellbore schedule.

Its lease has reported 59.8K barrels of oil and 807K mcf of gas since February 2019, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
