Parker Farms 25 #4 (API 42-317-36989) is a well in Martin County operated by Diamondback E&P LLC, completed February 14, 2012 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 8, 2011, permitted to 10,820 ft.
It was permitted by Cobra Oil & Gas Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Strawn, Mississippian.
Its lease has reported 406K barrels of oil and 1.09M mcf of gas since June 2011, last reporting volume in April 2026. The lease carries 7 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
1 log loaded from the RRC's log index, the latest received May 29, 2014. 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.
