Parks Bell #3908 (API 42-135-41498) is a well in Ector County operated by Cog Operating LLC, completed June 27, 2012 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 23, 2012, permitted to 10,972 ft.

It was permitted by Rsp Permian, LLC and has since transferred to Cog Operating LLC on the wellbore schedule.

Its lease has reported 3.03M barrels of oil and 3.87M mcf of gas since June 2008, last reporting volume in April 2026. The lease carries 28 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 May 13, 2013. 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.
