Annis #13 (API 42-433-32231) is a plugged well in Stonewall County, plugged July 31, 2002, last operated by Grayrock Energy II LLC.

The RRC has issued one drilling permit, issued April 3, 1987, permitted to 5,500 ft.

It was permitted by Martin Oil CO. and has since transferred to Grayrock Energy II LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Stockweather Lime, Swastika Sd, Canyon.

Its lease has reported 92.8K barrels of oil and 7.76K mcf of gas since January 1993, last reporting in July 2026. The lease carries 11 wells, so these are lease totals, not this well alone.
