Holt #4CB
Taylor County · Lake Kirby field · Producing · Horizontal
Holt #4CB (API 42-441-34232) is a horizontal well in Taylor County operated by Mesa Ridge Holdings LLC, completed August 15, 2008 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued March 31, 2008, permitted to 1,998 ft.
It was permitted by Central Basin Oil Inv. Inc. and has since transferred to Mesa Ridge Holdings LLC on the wellbore schedule.
Completion filings report one formation top, including Flippen Lime.
Its lease has reported 11K barrels of oil and 29 mcf of gas since January 1993, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
