Tumlinson A #1 Gas Unit #4 (API 42-293-32039) is a well in Limestone County operated by Hilcorp Energy Company, completed November 14, 2008 and listed as swr-10-well on the RRC schedule.

The RRC has issued one drilling permit, issued October 8, 2007, permitted to 14,600 ft.

It was permitted by Xto Energy Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 6 formation tops, including BMA, Pettit, Travis Peak, Cv Consolidated.

Its 3 leases have reported 666 barrels of oil and 2.05M mcf of gas since November 2008, last reporting volume in April 2026. The leases carry 3 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 Aug 17, 2011. 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.
