Wheeler 44 #2 (API 42-317-41042) is a well in Martin County operated by Oxyrock Operating LLC, completed April 23, 2018 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 20, 2017, permitted to 11,551 ft.
It was permitted by Crownquest Operating, LLC and has since transferred to Oxyrock Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Yates, Grayburg, San Andres, Spraberry.
Its lease has reported 135K barrels of oil and 380K mcf of gas since November 2017, last reporting volume in August 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

Click a log to get its files from the RRC (free account). It opens in a new tab on the RRC's log search for this well, which lists each file to view or download; the RRC has no address for a single file.

"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.
