Neal #505 (API 42-461-37451) is a plugged well in Upton County, plugged April 7, 2017, last operated by Saxum Opco LLC.

The RRC has issued one drilling permit, issued June 30, 2011, permitted to 11,600 ft.

It was permitted by Callon Petroleum Operating CO and has since transferred to Saxum Opco LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.

Its lease has reported 6.02M barrels of oil and 19.6M mcf of gas since June 2010, last reporting volume in April 2026. The lease carries 66 wells, so these are lease totals, not this well alone.

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

2 logs loaded from the RRC's log index, the latest received Feb 17, 2015. Neutron, Resistivity. 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.
