Matlock-Fullerton #18 (API 42-237-39208) is a well in Jack County operated by Mokan Capital LLC, completed October 17, 2013 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued April 1, 2008, permitted to 1,050 ft.

It was permitted by Jrj Oil & Gas LLC and has since transferred to Mokan Capital LLC on the wellbore schedule.

Completion filings report 2 formation tops, including Gunsight, Gun Sight Sand.

Its lease has reported 5.74K barrels of oil and 57 mcf of gas since January 1993, last reporting in July 2026. The lease carries 21 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.
