Chisum Roy R. #4
Kent County · Boomerang S. (Strawn Lime) field · Shut In · Vertical
Chisum Roy R. #4 (API 42-263-30647) is a well in Kent County operated by Three Span Oil & Gas Inc., completed December 28, 2009 and listed as shut in on the RRC schedule, shut in February 1, 2015.
The RRC has issued one drilling permit (amended once), issued May 23, 1979, permitted to 6,695 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 Tubb, Vale, Coleman Junction, Pennsylvanian.
Its lease has reported 176K barrels of oil and 77.5K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
