Jack County · Neale (Marble Falls) field · Vertical
Hamman D #4 (API 42-237-39725) is a plugged well in Jack County, plugged May 28, 2021, last operated by Oakridge Oil And Gas LP.
The RRC has issued one drilling permit (amended once), issued March 18, 2013, permitted to 6,500 ft.
It was permitted by Atlas Barnett, LLC and has since transferred to Oakridge Oil And Gas LP on the wellbore schedule.
Completion filings report 4 formation tops, including Caddo, Pregnant Shale, Marble Falls, Barnett.
Its 2 leases have reported 15.4K barrels of oil and 1.33M mcf of gas since April 2013, with no volume in the three years through April 2026. The leases carry 6 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jul 10, 2016. 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.
