Medarby Unit #20W (API 42-219-37043) is a well in Hockley County operated by Bce-Mach Iii LLC, completed September 8, 2008 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued April 23, 2008, permitted to 5,000 ft.

It was permitted by Chevron U. S. A. Inc. and has since transferred to Bce-Mach Iii LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Rustler, Salt, Yates, San Andres.

Its lease has reported 3.81M barrels of oil and 1.3M mcf of gas since January 1993, last reporting in July 2026. The lease carries 63 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 226K barrels injected in the 12 months reported through February 2026.

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