Mallet L&C CO. #210 (API 42-219-36871) is a well in Hockley County operated by Ctoc Energy LLC, completed March 29, 2006 and listed as shut in on the RRC schedule, shut in March 1, 2018.
The RRC has issued one drilling permit (amended once), issued December 7, 2005, permitted to 5,260 ft.
It was permitted by Merit Energy Company and has since transferred to Ctoc Energy LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Yates, San Andres, Main San Andres.
Its lease has reported 406K barrels of oil and 810K mcf of gas since November 2005, last reporting volume in August 2026. The lease carries 37 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
2 logs loaded from the RRC's log index, the latest received Dec 7, 2006. Density, Gamma ray, 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.
