Blankenship Heirs #1 (API 42-387-30453) is a horizontal well in Red River County operated by Cali Crude LLC, completed April 4, 1996.

The RRC has issued 2 drilling permits between 1995 and 1996, permitted to 5,500 ft.

It was permitted by Genesis Producing Company and has since transferred to Cali Crude LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Paluky, Paluxy, Massive, Rodessa.

Its 4 leases have reported 222K barrels of oil since April 1995, last reporting in July 2026. The leases carry 24 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.
