1966 Partnership #6
Trinity County · M. Gaston (Carrizo -B-) field · NO Production · Vertical
1966 Partnership #6 (API 42-455-30481) is a well in Trinity County operated by Upstream Resource Partners LLC, completed September 7, 2005 and listed as no production on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued May 26, 2004, permitted to 2,000 ft.
It was permitted by Triple "B" Production Drlg Inc and has since transferred to Upstream Resource Partners LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Sparta, Queen City, Carrizo.
Its lease has reported 176K barrels of oil and 9 mcf of gas since January 1993, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
