Howard County · Howard Glasscock (Consolidated) field · Injection · Vertical
Roberts Dora #135W (API 42-227-35353) is a well in Howard County operated by Apache Corporation, completed March 19, 2022 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued July 20, 1999, permitted to 3,000 ft.
It was permitted by Westport Oil And Gas Company Inc and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 4 formation tops, including Graayburg, Grayburg, San Andres, Glorieta.
Its 2 leases have reported 1.1M barrels of oil and 39K mcf of gas since January 1993, last reporting in July 2026. The leases carry 120 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 46.9K barrels injected in the 12 months reported through December 2025.
