Wichita County · Wichita County Regular field · Shut IN · Vertical
Chilson Lylan #1 (API 42-485-40220) is a well in Wichita County operated by R2q Operating LLC, completed April 8, 1985 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued December 27, 1984, permitted to 5,200 ft.
It was permitted by Winfrey, W. C. and has since transferred to R2q Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including KMA, Caddo, Ellenburger.
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.
