It was permitted by Diamond Petroleum and has since transferred to Driscoll S.W.D. Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Anacacho, Anachaco, Austin Chalk.
Its lease has reported 1 barrels of oil and 2 mcf of gas since January 1993, last reporting in August 2003. The lease carries 2 wells, so these are lease totals, not this well alone.
