La Salle County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Jasik Ranch A Unit #12H (API 42-283-35831) is a horizontal well in La Salle County operated by Javelin Energy Partners Mgmt LLC, completed June 19, 2017 and listed as producing on the RRC schedule, shut in July 1, 2025.
The RRC has issued one drilling permit, issued September 20, 2016, permitted to 7,664 ft.
It was permitted by Carrizo (Eagle Ford) LLC and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.
Completion filings report 11 formation tops, including Midway, Escondido, Olmos, Austin Chalk.
Its 3 leases have reported 3.38M barrels of oil and 8.73M mcf of gas since January 2013, last reporting volume in March 2026. The leases carry 30 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Mar 2, 2020. 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.
