Blackwell Raymond #40 (API 42-055-33715) is a well in Caldwell County operated by Castillo Oil Company LLC, completed January 4, 1985 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 8, 1984, permitted to 2,500 ft.
It was permitted by Tri-City Oil Company and has since transferred to Castillo Oil Company LLC on the wellbore schedule.

Its lease has reported 30.4K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 31 wells, so these are lease totals, not this well alone.
