Livingston Ranch 4 #401
Knox County · Bobby B (Tann) field · Shut IN · Vertical
Livingston Ranch 4 #401 (API 42-275-31766) is a well in Knox County operated by Royal Oryx OG LLC, completed February 4, 1987 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued April 16, 1986, permitted to 2,700 ft.
It was permitted by Livingston, F. L. and has since transferred to Royal Oryx OG LLC on the wellbore schedule.
Completion filings report one formation top, including Tannehill.
Its lease has reported 62.3K barrels of oil and 171 mcf of gas since January 1993, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Livingston, F. L.; the EWA schedule now lists a different operator.
