Lake Trammel Unit #13W (API 42-353-01046) is a plugged well in Nolan County, plugged March 29, 2012, last operated by Grayrock Energy II LLC.
The RRC has issued one drilling permit, issued January 2, 2013, permitted to 5,800 ft.
It was permitted by Merit Energy Company and has since transferred to Grayrock Energy II LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Vale Shale, Valera, Wolfcamp, Coleman Junction.
Its lease has reported 3.85M barrels of oil and 2.09M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 203 wells, so these are lease totals, not this well alone.
