- Not one formation; the well must be completed in one of them, and no target formation is stated. The district's wildcat field is also on the permit.
Mabee C #30 (API 42-317-34856) is a well in Martin County operated by Diamondback E&P LLC, completed July 12, 2007 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued January 26, 2007, permitted to 10,300 ft.
It was permitted by Chesapeake Operating, Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 9 formation tops, including Red Beds, Rustler, Tansill, Grayburg.
Its lease has reported 4.29M barrels of oil and 9.83M mcf of gas since December 2005, last reporting volume in August 2026. The lease carries 61 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.

Operator on the lease's P-4
Each operator named on the P-4 filings for this well's lease (a gas well is its own lease), from the date its filing took effect. The P-4 is filed by lease, so a date before the well was drilled is the lease's.

"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.
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.
