Sentry C.C. #1 (API 42-003-34189) is a well in Andrews County operated by Montare Operating Ltd., completed June 20, 1984 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued May 10, 1984, permitted to 4,750 ft.
It was permitted by Rankin Oil CO. and has since transferred to Montare Operating Ltd. on the wellbore schedule.
Completion filings report 3 formation tops, including Yates, Grayburg, San Andres.
Its lease has reported 150K barrels of oil and 96.4K mcf of gas since January 1993, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
