Senkel-Hawkins #A1 (API 42-503-36446) is a well in Young County operated by Karper Oil & Gas Corporation, completed September 30, 2015 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued November 23, 1982, permitted to 5,100 ft.
It was permitted by Senkel, Wesley, Inc. and has since transferred to Karper Oil & Gas Corporation on the wellbore schedule.

Its lease has reported 68.9K barrels of oil and 35.3K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
