Loving County · Mason N. (Delaware Sand) field · Shut In · Vertical
North Mason /Delaware Sand/ Unit #1503 (API 42-301-30833) is a well in Loving County operated by R2q Operating LLC, completed September 22, 1988 and listed as shut in on the RRC schedule, shut in July 1, 2020.
The RRC has issued one drilling permit, issued July 6, 1988, permitted to 4,300 ft.
It was permitted by Marathon Oil Company and has since transferred to R2q Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Delaware.
Its lease has reported 561K barrels of oil and 704K mcf of gas since January 1993, last reporting in July 2026. The lease carries 59 wells, so these are lease totals, not this well alone.
