Martin Ranch B #31H (API 42-283-34630) is a horizontal well in La Salle County operated by Verdun Oil & Gas LLC, completed May 24, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued March 14, 2014, permitted to 10,000 ft.

It was permitted by Matador Production Company and has since transferred to Verdun Oil & Gas LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Yegua, Sparta, Queen City, Wilcox.

Its lease has reported 1.35M barrels of oil and 3.43M mcf of gas since February 2012, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
