South Lake Trammel Unit #64
Nolan County · Lake Trammel S. (Canyon) field · Shut IN · Vertical
South Lake Trammel Unit #64 (API 42-353-32435) is a well in Nolan County operated by Grayrock Energy II LLC, completed August 19, 1996 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued June 17, 1996, permitted to 7,200 ft.
It was permitted by Lavanco Energy, Inc. and has since transferred to Grayrock Energy II LLC on the wellbore schedule.
Completion filings report one formation top, including Canyon.
Its lease has reported 217K barrels of oil and 465K mcf of gas since January 1993, last reporting in July 2026. The lease carries 54 wells, so these are lease totals, not this well alone.
Operator of record
