Calverley #4 (API 42-173-36036) is a well in Glasscock County operated by Ovintiv USA Inc., completed January 5, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 4, 2013, permitted to 10,400 ft.
It was permitted by Athlon Energy Operating LLC and has since transferred to Ovintiv USA Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Dean, Strawn, Atoka.
Its lease has reported 117K barrels of oil and 889K mcf of gas since May 2013, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
