North Robertson Unit #3514 B (API 42-165-33669) is a well in Gaines County operated by Bce-Mach Iii LLC, completed October 5, 1987.

The RRC has issued one drilling permit (amended once), issued July 31, 1986, permitted to 7,500 ft.

It was permitted by Sabinal Energy Operating, LLC and has since transferred to Bce-Mach Iii LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Glorieta, Clear Fork, Tubb.

Its lease has reported 25.7M barrels of oil and 12.1M mcf of gas since January 1993, last reporting in July 2026. The lease carries 562 wells, so these are lease totals, not this well alone.
