Martin County · Spraberry (Trend Area) field · Shut IN  · Horizontal

Massasauga D #11HA (API 42-317-43690) is a horizontal well in Martin County operated by Oxyrock Operating LLC, completed July 29, 2023 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued July 20, 2021, permitted to 10,500 ft.

It was permitted by Crownquest Operating, LLC and has since transferred to Oxyrock Operating LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Yates, Grayburg, San Andres, Glorieta.

Its lease has reported 1.1M barrels of oil and 2.03M mcf of gas since June 2020, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
