The RRC has issued one drilling permit (amended once), issued November 1, 1995, permitted to 4,440 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Olsen Energy Inc. on the wellbore schedule.

Its lease has reported 110K barrels of oil and 249K mcf of gas since February 1996, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
