Card Hcwc & I Dist. 6 Unit #1 (API 42-215-31130) is a well in Hidalgo County operated by Winchester Energy Operating CO., completed November 8, 1981.

The RRC has issued 4 drilling permits (amended once) between 1981 and 2001, permitted to 10,200 ft.

It was permitted by Owl Creek Production CO., Inc. and has since transferred to Winchester Energy Operating CO. on the wellbore schedule.

Completion filings report 7 formation tops, including "R" Sand, R Sand, "T" Sand, T Sand.

Its 5 leases have reported 18.3K barrels of oil and 383K mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 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.
