La Salle County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Martin Ranch B #4H (API 42-283-32952) is a horizontal well in La Salle County operated by Verdun Oil & Gas LLC, completed February 18, 2012 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued December 15, 2011, permitted to 9,327 ft.
It was permitted by Matador Production Company and has since transferred to Verdun Oil & Gas LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.
Its lease has reported 1.35M barrels of oil and 3.43M mcf of gas since February 2012, last reporting volume in April 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
