Wichita County · Wichita County Regular field · Shut IN · Vertical
Chilson Lylan #7S (API 42-485-43641) is a well in Wichita County operated by R2q Operating LLC, completed October 15, 2001 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued August 20, 2001, permitted to 1,999 ft.
It was permitted by Sissom Oil and has since transferred to R2q Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Cisco.
Its lease has reported 19.8K barrels of oil and 20 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.
Operator of record
Permitted by Sissom Oil; the EWA schedule now lists a different operator.
