Mustang #3H
McMullen County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Mustang #3H (API 42-311-35214) is a horizontal well in Mcmullen County operated by Javelin Energy Partners Mgmt LLC, completed March 16, 2013 and listed as producing on the RRC schedule, shut in December 1, 2025.
The RRC has issued one drilling permit, issued November 30, 2012, permitted to 10,038 ft.
It was permitted by Abraxas Petroleum Corporation and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.
Its 2 leases have reported 960K barrels of oil and 1.8M mcf of gas since December 2012, last reporting volume in March 2026. The leases carry 10 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 9, 2016. 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.
