Andrews County · Fuhrman-Mascho field · Producing · Vertical
Zeismer #8 (API 42-003-40927) is a well in Andrews County operated by Crescent Energy Operating LLC, completed November 9, 2011 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 24, 2008, permitted to 4,801 ft.
It was permitted by OK Arena Operating Company and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Rustler, Yates, Grayburg, Gryburg.
Its lease has reported 197K barrels of oil and 210K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 13 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Dec 10, 2009. 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.
