Frances #1 (API 42-135-40488) is a well in Ector County operated by Diamondback E&P LLC, completed November 6, 2011 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued September 13, 2010, permitted to 10,600 ft.

It was permitted by Oxy USA Wtp LP and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Spraberry, Wolfcamp, Strawn.

Its lease has reported 346K barrels of oil and 804K mcf of gas since September 2009, last reporting in July 2026. The lease carries 17 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.
