Wylie A #4012 (API 42-101-30486) is a well in Cottle County operated by Daylight Petroleum LLC, completed August 19, 1988 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued May 12, 1988, permitted to 6,000 ft.
It was permitted by Whalen Drilling & Mining CO. and has since transferred to Daylight Petroleum LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Coleman Junction, Tannehill, Flippen Reef.
Its lease has reported 296K barrels of oil and 22 mcf of gas since January 1993, last reporting in July 2026. The lease carries 21 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 86.3K barrels injected in the 12 months reported through April 2026.
