Sutton County · Fort Terrett Ranch (Canyon 2800) field · Horizontal
FT. Terrett Ranch /Canyon LM/ U. #21H (API 42-435-10225) is a former disposal or injection well in Sutton County, last operated by Rocking R Investments Inc.; its UIC permit is no longer active.
The RRC has issued 2 drilling permits (amended once) between 1990 and 2012, permitted to 3,999 ft.
It was permitted by Mextex Operating Company and has since transferred to Rocking R Investments Inc. on the wellbore schedule.
Completion filings report 2 formation tops, including Adams Branch, Canyon.
Its 3 leases have reported 559K barrels of oil and 210K mcf of gas since January 1993, last reporting in July 2026. The leases carry 73 wells, so these are lease totals, not this well alone.
