Holt O.B. -J- #4 (API 42-135-33001) is a plugged well in Ector County, plugged May 24, 2018, last operated by Occidental Permian Ltd..
The RRC has issued one drilling permit, issued May 10, 1978, permitted to 4,675 ft.
It was permitted by Amoco Production Company and has since transferred to Occidental Permian Ltd. on the wellbore schedule.
Completion filings report 3 formation tops, including Queen, Grayburg, San Andres.
Its lease has reported 31.8K barrels of oil and 9.88K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
