Constantine #1H (API 42-149-33502) is a horizontal well in Fayette County operated by Paleo Oil Company LLC, completed February 27, 2020 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued January 8, 2020, permitted to 10,500 ft.
It was permitted by Ironroc Energy and has since transferred to Paleo Oil Company LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Taylor, Anacacho, Austin Chalk, Glen Rose.
Its lease has reported 851K barrels of oil and 3.08M mcf of gas since February 2020, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
