Sweeney H. O. #12 (API 42-181-31585) is a well in Grayson County operated by R2q Operating LLC, completed March 3, 2018 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued September 16, 2016, permitted to 11,000 ft.
It was permitted by Blackwell Exp & Development, LLC and has since transferred to R2q Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Barnes Sand, Baker Sand, Bruhlmeyer, Carraway Sand.
Its lease has reported 91.3K barrels of oil and 1.38M mcf of gas since October 1999, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
