Halfmann Delbert #2
Glasscock County · Saint Lawrence (Strawn) field · Temp Abandoned · Vertical
Halfmann Delbert #2 (API 42-173-31840) is a well in Glasscock County operated by Xto Energy Inc., completed February 9, 1996 and listed as temp abandoned on the RRC schedule, shut in February 1, 2019.
The RRC has issued one drilling permit, issued April 2, 1985, permitted to 12,100 ft.
It was permitted by Exxon Corp. and has since transferred to Xto Energy Inc. on the wellbore schedule.
Completion filings report 18 formation tops, including Dewey Lake, Rustler, Salado, Tansill.
Its 2 leases have reported 1.36K barrels of oil and 472K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
