The RRC has issued 2 drilling permits between 1995 and 1997, permitted to 11,000 ft.
It was permitted by Brigham Oil & Gas, L.P. and has since transferred to Cobra Oil & Gas Corporation on the wellbore schedule.
Completion filings report 4 formation tops, including Spraberry, Dean, Wolfcamp, Pennsylvanian.
Its 3 leases have reported 27K barrels of oil and 16.5K mcf of gas since May 1994, last reporting in October 1998. The leases carry 5 wells, so these are lease totals, not this well alone.
