Samson University 9 #1 (API 42-003-41516) is a well in Andrews County operated by Sabalo II Operating LLC, completed June 14, 2010 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued March 9, 2010, permitted to 11,350 ft.

It was permitted by Williams, Clayton Energy, Inc. and has since transferred to Sabalo II Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Clear Fork, Spraberry, Wolfcamp, Strawn.

Its lease has reported 663K barrels of oil and 1.39M mcf of gas since June 2010, last reporting volume in April 2026. The lease carries 8 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

1 log loaded from the RRC's log index, the latest received May 13, 2013. 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.
