Roberts Unit #3734A (API 42-501-33759) is a well in Yoakum County operated by Hilcorp Energy Company, completed July 20, 2011 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued November 19, 1991, permitted to 5,473 ft.

It was permitted by Texaco E & P Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 3 formation tops, including Rustler, Yates, San Andres.

Its lease has reported 18.3M barrels of oil and 12.3M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 622 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 125K barrels injected in the 12 months reported through September 2025.

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