Hassenstab Leonard #1 (API 42-357-32011) is a horizontal well in Ochiltree County operated by Sunlight Exploration Inc., completed February 4, 1993 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 6, 1992, permitted to 7,500 ft.
It was permitted by Norcen Explorer, Inc. and has since transferred to Sunlight Exploration Inc. on the wellbore schedule.
Completion filings report 6 formation tops, including Pennsylvanian, Base Heebner, Douglas, Kansas City.
Its lease has reported 105K barrels of oil and 240K mcf of gas since February 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
