Slash -O- #1 (API 42-301-30763) is a well in Loving County operated by Forest Oil Corporation, completed September 23, 1988.
The RRC has issued 2 drilling permits between 1987 and 1988, permitted to 6,600 ft.
It was permitted by Parker & Parsley Petroleum CO. and has since transferred to Forest Oil Corporation on the wellbore schedule.
Completion filings report 7 formation tops, including Lamar, Ramsey, Top Ramsey, Cherry Canyon.
Its 2 leases have reported 110K barrels of oil and 130K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
