Martin County · Spraberry (Trend Area) field · Producing · Vertical
Nebbiolo #1 (API 42-317-38320) is a well in Martin County operated by Ovintiv USA Inc., completed April 26, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued December 12, 2012, permitted to 11,499 ft.
It was permitted by W&T Offshore, Inc. and has since transferred to Ovintiv USA Inc. on the wellbore schedule.
Completion filings report 7 formation tops, including Clear Fork, Spraberry, Wolfcamp, Dean.
Its lease has reported 160K barrels of oil and 326K mcf of gas since April 2013, last reporting volume in April 2026. The lease carries 3 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Mar 31, 2016. Density, 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.
