Strain Ranch 12-1-B #4103H (API 42-317-41751) is a horizontal well in Martin County operated by Pioneer Natural Res. USA Inc., completed March 26, 2019 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit (amended twice), issued September 6, 2018, permitted to 9,239 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 10 formation tops, including San Andres, Clear Fork, Spraberry, Dean.

Its lease has reported 1.16M barrels of oil and 3.16M mcf of gas since March 2019, last reporting in July 2026. The lease carries 3 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.
