Mabee C #40 (API 42-317-39926) is a well in Martin County operated by Diamondback E&P LLC, completed December 12, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 9, 2014, permitted to 11,755 ft.
It was permitted by Qep Energy Company and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Santa Rosa, Yates, Queen, Grayburg.
Its lease has reported 4.29M barrels of oil and 9.82M mcf of gas since December 2005, last reporting volume in April 2026. The lease carries 61 wells, so these are lease totals, not this well alone.

Completion filings
W-2 and G-1 reports on record in the RRC wellbore file, newest first. The suffix identifies the wellbore or completion event. The record date is the RRC's own date on the record, not the day the report was filed: 462,034 of the state's filings carry 1984-01-12. About these reports →

Well logs
2 logs loaded from the RRC's log index, 2 of them with a digital LAS file, the latest received Nov 28, 2017. Cement bond, Gamma ray. 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.
