Throckmorton County · Throckmorton County Regular field · Producing · Vertical
Daws Margaret M. #B 2 (API 42-447-35903) is a well in Throckmorton County operated by S2 Oil LLC (1), completed November 21, 1999 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 1, 1998, permitted to 1,000 ft.
It was permitted by Shack, Bill and has since transferred to S2 Oil LLC (1) on the wellbore schedule.
Completion filings report one formation top, including King Sand.
Its lease has reported 39.2K barrels of oil and 137 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.
Operator of record
Permitted by Shack, Bill; the EWA schedule now lists a different operator.
