La Salle County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Altito A 27a Unit #273H (API 42-283-35359) is a horizontal well in La Salle County operated by Verdun Oil EF II LLC, completed March 23, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued February 6, 2015, permitted to 9,035 ft.
It was permitted by EP Energy E&P Company, L.P. and has since transferred to Verdun Oil EF II LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Escondido, Olmos, Austin Chalk, Eagle Ford.
Its lease has reported 225K barrels of oil and 564K mcf of gas since March 2015, last reporting volume in April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

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 Nov 3, 2015. 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.
