Milam County · Minerva-Rockdale field · Producing · Vertical
Coulter -B- #10 (API 42-331-34450) is a well in Milam County operated by Speckle Trout Operating LLC, completed February 28, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 2, 2012, permitted to 1,225 ft.
It was permitted by Stingray Oil Company, Inc. and has since transferred to Speckle Trout Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Navarro.
Its lease has reported 35.7K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 12 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Stingray Oil Company, Inc.; the EWA schedule now lists a different operator.
