Runnels County · McMillan field  · Vertical

Bull Field Unit #4WS (API 42-399-34337) is a plugged well in Runnels County, plugged October 31, 2024, last operated by Jericho Energy Operations LLC.

The RRC has issued 2 drilling permits between 1994 and 2009, permitted to 4,750 ft.

It was permitted by Hgn Operating I, LLC and has since transferred to Jericho Energy Operations LLC on the wellbore schedule.

Completion filings report 6 formation tops, including Saddle Creek, Breckenridge, Palo Pinto, Goen.

Its 3 leases have reported 140K barrels of oil and 288K mcf of gas since July 1993, last reporting in July 2026. The leases carry 13 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.
