The RRC has issued one drilling permit (amended once), issued March 13, 1987, permitted to 2,238 ft.
It was permitted by Hazelett Oil Company, Inc. and has since transferred to Proline Energy Resources Inc on the wellbore schedule.
Completion filings report 4 formation tops, including Wilcox, Midway, Taylor, Dale-Lime.
Its lease has reported 240K barrels of oil and 112K mcf of gas since January 1993, last reporting in July 2026. The lease carries 22 wells, so these are lease totals, not this well alone.
