Martin County · Spraberry (Trend Area) field · Vertical
Welch & Welch #2 (API 42-317-33259) is a plugged well in Martin County, plugged October 4, 2012, last operated by Pioneer Natural Res. USA Inc..
The RRC has issued one drilling permit, issued September 27, 1985, permitted to 9,425 ft.
It was permitted by Brown, Tom Inc. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 4 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.
Its lease has reported 32.7K barrels of oil and 128K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jan 30, 2012. 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.
