Foster H. S. #21 (API 42-135-38260) is a well in Ector County operated by Helms Oil & Gas LLC, completed June 10, 2003 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued September 13, 2002, permitted to 4,550 ft.
It was permitted by Turrentine Oil And Gas, Inc. and has since transferred to Helms Oil & Gas LLC on the wellbore schedule.
Completion filings report one formation top, including Grayburg.
Its lease has reported 577K barrels of oil and 409K mcf of gas since January 1993, last reporting in July 2026. The lease carries 25 wells, so these are lease totals, not this well alone.
