Denison S #1 (API 42-433-32668) is a well in Stonewall County operated by Grayrock Energy II LLC, completed December 15, 1990 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued November 28, 1990, permitted to 4,300 ft.

It was permitted by Wetzel, John M. and has since transferred to Grayrock Energy II LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Base/Coleman Junc, Gunsight, Canyon.

Its lease has reported 32.9K barrels of oil and 667 mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
