Wheeler County · Stiles Ranch (Granite Wash Cons) field · Producing · Vertical
Bartz 19 #3019 (API 42-483-31731) is a well in Wheeler County operated by Formentera Operations LLC, completed July 25, 2025 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended twice) between 2004 and 2007, permitted to 16,510 ft.
It was permitted by Apache Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Caldwell, Cherokee, Granite Wash, Atoka.
Its 2 leases have reported 27.6K barrels of oil and 1.72M mcf of gas since April 2005, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

Surface location
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.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
1 log loaded from the RRC's log index, the latest received Jan 29, 2008. Density, 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.
