Frances 12-1-B #4104H (API 42-317-42880) is a horizontal well in Martin County operated by Pioneer Natural Res. USA Inc., completed September 9, 2020 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued January 30, 2020, permitted to 8,995 ft.

It was permitted by Parsley Energy Operations, LLC and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.

Completion filings report 9 formation tops, including Tansil, Yates, Seven Rivers, Queen.

Its lease has reported 919K barrels of oil and 1.86M mcf of gas since September 2020, last reporting in July 2026. The lease carries 2 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.
