Oil Dev. CO. Of Tex. #6 (API 42-195-30809) is a well in Hansford County operated by Highmark Energy Operating LLC, completed September 10, 2010 and listed as swr-10-well on the RRC schedule.

The RRC has issued one drilling permit, issued July 22, 1981, permitted to 6,550 ft.

It was permitted by Exxon Corp. and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.

Completion filings report 7 formation tops, including Cottage Grove, Admire, Douglas, Tonkawa.

Its 3 leases have reported 9.58K barrels of oil and 347K mcf of gas since January 1993, last reporting in July 2026. The leases carry 6 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.
