WELL · 42-173-31639 · DISTRICT 8
Glass #1
Glasscock County · R.W.P. (Strawn) field · Vertical
Glass #1 (API 42-173-31639) is a well in Glasscock County operated by Landmark IP LLC, completed January 1, 1986.
The RRC has issued 3 drilling permits between 1984 and 1989, permitted to 10,800 ft.
It was permitted by Union Texas Petroleum Corp. and has since transferred to Landmark IP LLC on the wellbore schedule.
Completion filings report 7 formation tops, including Clear Fork, Wolfcamp, Pennsylvanian, Strawn.
Its 2 leases have reported 235K barrels of oil and 2.39M mcf of gas since January 1993, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Union Texas Petroleum Corp.; the EWA schedule now lists a different operator.
