Howard County · Luther E. (Canyon Reef) field · Injection · Vertical
Cao #1R (API 42-227-40627) is a well in Howard County operated by Select Water Solutions LLC, completed October 13, 2021 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued February 26, 2020, permitted to 5,800 ft.
It was permitted by Platform Operating, LLC and has since transferred to Select Water Solutions LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Santa Rosa, Rustler, Yates, Seven Rivers.
Its lease has reported 17K barrels of oil and 25.2K mcf of gas since August 1995, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 224K barrels injected in the 12 months reported through December 2025; TexNet located 1 M2+ earthquakes within 10 km over the last two years.
