Spraberry Driver Unit #4203D (API 42-173-32480) is a well in Glasscock County operated by Pioneer Natural Res. USA Inc., completed April 5, 2018 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued January 5, 1995, permitted to 5,000 ft.

It was permitted by Parker & Parsley Development CO. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.

Completion filings report 2 formation tops, including Base Of Salt, San Andres.

Its lease has reported 39.2M barrels of oil and 144M mcf of gas since January 1993, last reporting in July 2026. The lease carries 901 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 26.5K barrels injected in the 12 months reported through January 2026.

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