Holt O. B. -C- #21W (API 42-135-36572) is a plugged well in Ector County, plugged August 8, 2023, last operated by Texland Petroleum L.P..
The RRC has issued one drilling permit, issued December 20, 1991, permitted to 5,350 ft.
It was permitted by Union Oil Company Of California and has since transferred to Texland Petroleum L.P. on the wellbore schedule.
Completion filings report 2 formation tops, including Grayburg, San Andres.
Its lease has reported 2.52M barrels of oil and 335K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 32 wells, so these are lease totals, not this well alone.
