Yoakum County · Wasson field · Injection · Vertical
Roberts Unit #3240 (API 42-501-35170) is a well in Yoakum County operated by Hilcorp Energy Company, completed June 6, 2013 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued March 23, 2005, permitted to 5,520 ft.
It was permitted by Apache Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 6 formation tops, including Rustler, Yates, Seven Rivers, Queen.
Its lease has reported 18.4M barrels of oil and 12.3M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 623 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 46K barrels injected in the 12 months reported through September 2025.

No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.
