Dimmit County · Briscoe Ranch (Eagleford) field · Producing · Horizontal
Lazy A Cotulla Unit Dim #H 3H (API 42-127-37227) is a horizontal well in Dimmit County operated by Ineos USA Oil & Gas LLC, completed November 28, 2016 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued November 19, 2015, permitted to 7,447 ft.
It was permitted by Chesapeake Operating, L.L.C. and has since transferred to Ineos USA Oil & Gas LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Escondido, Olmos, San Miguel, Anacacho.
Its lease has reported 552K barrels of oil and 1.44M mcf of gas since January 2016, last reporting volume in April 2026. The lease carries 3 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, 1 of it with a digital LAS file, the latest received Aug 23, 2019. Gamma ray. 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.
