Duval County · Tarancahuas field · Vertical
Rosemary #47 (API 42-131-36740) is a plugged well in Duval County, plugged March 23, 1999, last operated by Hbc Oil Company LLC.
The RRC has issued one drilling permit, issued June 25, 1985, permitted to 2,300 ft.
It was permitted by Cox, Edwin L. & Hamon, Jake L. and has since transferred to Hbc Oil Company LLC on the wellbore schedule.
Completion filings report one formation top, including Tarancahuas.
Its lease has reported 111K barrels of oil and 23 mcf of gas since January 1993, last reporting in July 2026. The lease carries 19 wells, so these are lease totals, not this well alone.
