Slash -B- #1 (API 42-301-30707) is a well in Loving County operated by Last Mile Production LLC, completed October 6, 1986 and listed as shut in on the RRC schedule, shut in July 1, 2020.
The RRC has issued one drilling permit, issued July 31, 1986, permitted to 6,600 ft.
It was permitted by Parker & Parsley Petroleum CO. and has since transferred to Last Mile Production LLC on the wellbore schedule.
Completion filings report 5 formation tops, including T. Lamar, T. Cherry Canyon, T. "G" Sand, T. "H" Sand.
Its 2 leases have reported 268K barrels of oil and 744K mcf of gas since January 1993, last reporting in July 2026. The leases carry 8 wells, so these are lease totals, not this well alone.
