Blagrave 54-59 #1 (API 42-317-36236) is a well in Martin County operated by Diamondback E&P LLC, completed January 20, 2011 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued August 24, 2010, permitted to 10,802 ft.

It was permitted by Endeavor Energy Resources L.P. 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 228K barrels of oil and 268K mcf of gas since January 2011, last reporting volume in August 2026. The lease carries 4 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Well logs

1 log loaded from the RRC's log index, the latest received Feb 15, 2012. 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.
