Ector County · Cowden North field · Horizontal
Holt O. B. #136H (API 42-135-37452) is a plugged horizontal well in Ector County, plugged May 23, 2012, last operated by Texland Petroleum L.P..
The RRC has issued 2 drilling permits between 1997 and 2000, permitted to 4,850 ft.
It was permitted by Texaco E & P Inc. and has since transferred to Texland Petroleum L.P. on the wellbore schedule.
Completion filings report one formation top, including Grayburg.
Its lease has reported 2.08M barrels of oil and 705K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 134 wells, so these are lease totals, not this well alone.
