Bronte Cambrian Unit #319
Coke County · Bronte (Cambrian) field · Shut IN · Vertical
Bronte Cambrian Unit #319 (API 42-081-31975) is a well in Coke County operated by R3 Operating Corporation, completed December 2, 2010 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued September 24, 2010, permitted to 6,000 ft.
It was permitted by Grandfield Consulting, Inc. and has since transferred to R3 Operating Corporation on the wellbore schedule.
Completion filings report one formation top, including Cambrian.
Its lease has reported 872K barrels of oil and 275K mcf of gas since January 1993, last reporting in July 2026. The lease carries 27 wells, so these are lease totals, not this well alone.
