The RRC has issued one drilling permit (amended once), issued May 25, 2011, permitted to 12,000 ft.
It was permitted by Berry Oil Comp. and has since transferred to Callon Petroleum Operating CO on the wellbore schedule.
Completion filings report 5 formation tops, including San Andres, Spraberry, Dean, Wolfcamp.
Its 2 leases have reported 126K barrels of oil and 168K mcf of gas since September 2010, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
