Rosemary #50 (API 42-131-39610) is a well in Duval County operated by Hbc Oil Company LLC, completed February 16, 2018 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 8, 2018, permitted to 2,300 ft.

It was permitted by Aurora Resources Corporation and has since transferred to Hbc Oil Company LLC on the wellbore schedule.

Completion filings report 9 formation tops, including Tarancahuas, Jackson, Catahoula, Miocene (undifferentiated).

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.
