Locklar -A- #1 (API 42-329-31970) is a plugged well in Midland County, plugged September 1, 2022, last operated by Pioneer Natural Res. USA Inc..

The RRC has issued one drilling permit, issued December 10, 1987, permitted to 9,525 ft.

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

Completion filings report 2 formation tops, including Spraberry, Dean.

Its lease has reported 124K barrels of oil and 384K mcf of gas since January 1993, with no volume in the three years through April 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.
