Chisum Roy R. #7
Kent County · Boomerang S. (Strawn Lime) field · Injection · Horizontal · Sidetrack
Chisum Roy R. #7 (API 42-263-31345) is a horizontal well in Kent County operated by Three Span Oil & Gas Inc., completed August 30, 2023 and listed as injection on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 1989 and 1995, permitted to 6,598 ft.
It was permitted by Marathon Oil Company and has since transferred to Three Span Oil & Gas Inc. on the wellbore schedule.
Completion filings report 5 formation tops, including Coleman Junction, Noodle Creek, Strawn, Canyon.
Its lease has reported 176K barrels of oil and 77.5K mcf of gas since January 1993, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 366K barrels injected in the 12 months reported through May 2026.
