Simpson-Mann B #2 (API 42-451-31806) is a plugged well in Tom Green County, plugged October 14, 2014, last operated by Tcs Petroleum CO. LLC.
The RRC has issued one drilling permit, issued July 29, 1987, permitted to 1,250 ft.
It was permitted by Lawrence, C. F. & Assoc. Inc. and has since transferred to Tcs Petroleum CO. LLC on the wellbore schedule.
Completion filings report one formation top, including San Angelo.
Its lease has reported 17.2K barrels of oil and 38 mcf of gas since January 1993, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
