Andrews County · Cowden North field · Producing · Vertical
Holt O.B. Grbg #502 (API 42-003-11018) is a well in Andrews County operated by Olsen Energy Inc., completed November 23, 1978 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 19, 1978, permitted to 9,110 ft.
It was permitted by Sun Exploration & Production CO. and has since transferred to Olsen Energy Inc. on the wellbore schedule.
Its lease has reported 386K barrels of oil and 57.4K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 97 wells, so these are lease totals, not this well alone.
