Bayliss #1 (API 42-329-31606) is a well in Midland County operated by Diamondback E&P LLC, completed December 29, 1985 and listed as shut in on the RRC schedule.

The RRC has issued 2 drilling permits in 1985, permitted to 12,000 ft.

It was permitted by Hcw Exploration, Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 6 formation tops, including Spraberry, Dean, Wolfcamp, Strawn.

Its 2 leases have reported 148K barrels of oil and 192K mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
