Martin County · Spraberry (Trend Area) R 40 Exc field · Producing · Horizontal
Glass Ranch A #1H (API 42-317-39396) is a horizontal well in Martin County operated by Pioneer Natural Res. USA Inc., completed February 10, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued April 26, 2014, permitted to 10,087 ft.
It was permitted by Devon Energy Production CO, L.P. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 10 formation tops, including Cisco, Santa Rosa, Yates, Queen.
Its lease has reported 526K barrels of oil and 1.08M mcf of gas since September 2014, last reporting volume in April 2026. The lease carries 3 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 Sep 28, 2018. Gamma ray. 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.
