Lake Trammel Unit #140 (API 42-353-32964) is a well in Nolan County operated by Grayrock Energy II LLC, completed May 30, 2008.

The RRC has issued 3 drilling permits (amended once) between 2007 and 2013, permitted to 7,200 ft.

It was permitted by Merit Energy Company and has since transferred to Grayrock Energy II LLC on the wellbore schedule.

Completion filings report one formation top, including Canyon.

Its 2 leases have reported 3.85M barrels of oil and 2.09M mcf of gas since January 1993, last reporting in July 2026. The leases carry 204 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.
