Green Gas Unit 1 #4 (API 42-401-34509) is a well in Rusk County operated by Buckhorn Operating LLC, completed December 23, 2007 and listed as swr-10-well on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued September 17, 2007, permitted to 11,050 ft.

It was permitted by Enduring Resources, LLC and has since transferred to Buckhorn Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Pettit, Travis Peak, Cotton Valley, Bossier.

Its 2 leases have reported 7.63K barrels of oil and 1.62M mcf of gas since December 2007, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Well logs

1 log loaded from the RRC's log index, the latest received Nov 23, 2010. Density, Neutron, 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.
