Jack County · Jack County Regular field · Producing · Vertical
Keyser #4 (API 42-237-37412) is a well in Jack County operated by Ray Herring Operating CO. LLC, completed March 18, 1988 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued October 7, 1987, permitted to 3,500 ft.
It was permitted by Herring, Ray and has since transferred to Ray Herring Operating CO. LLC on the wellbore schedule.
Completion filings report one formation top, including Bryson.
Its lease has reported 13.2K barrels of oil and 104K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
