Milam County · Minerva-Rockdale field · Shut In · Vertical
Cook Zelda #Z 42 (API 42-331-33817) is a well in Milam County operated by C & P Land Services LLC, completed March 25, 2011 and listed as shut in on the RRC schedule, shut in July 1, 2023.
The RRC has issued one drilling permit, issued January 28, 2011, permitted to 803 ft.
It was permitted by Omni Oil & Gas, Inc. and has since transferred to C & P Land Services LLC on the wellbore schedule.
Completion filings report one formation top, including Navarro.
Its lease has reported 184K barrels of oil and 98 mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 111 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Oct 27, 2011. 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.
