Njcu #13 (API 42-165-34183) is a well in Gaines County operated by White Rock Oil & Gas LLC, completed April 20, 2024 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued July 18, 1990, permitted to 7,355 ft.

It was permitted by Exxon Corp. and has since transferred to White Rock Oil & Gas LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Yates, Seven Rivers, San Andres, Glorieta.

Its 2 leases have reported 2.16M barrels of oil and 3.49M mcf of gas since January 1993, last reporting volume in March 2026. The leases carry 75 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 85.2K barrels injected in the 12 months reported through October 2025.

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

Well logs

1 log loaded from the RRC's log index, the latest received Nov 6, 2023. Neutron. 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.

"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.
