Estes #4 (API 42-103-35648) is a well in Crane County operated by Olsen Energy Inc., completed May 29, 2009 and listed as no production on the RRC schedule.
The RRC has issued one drilling permit, issued February 11, 2009, permitted to 6,150 ft.
It was permitted by Northstar Operating Company and has since transferred to Olsen Energy Inc. on the wellbore schedule.
Its lease has reported 11.7K barrels of oil and 60.1K mcf of gas since November 2007, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
