Andrews County · Spraberry (Trend Area) field · Horizontal
UL MS HZ Blk 6 B Unit #3107 (API 42-003-47602) is a horizontal well in Andrews County operated by Diamondback E&P LLC, completed November 14, 2017.
The RRC has issued one drilling permit (amended twice), issued July 17, 2017, permitted to 10,000 ft.
It was permitted by Ajax Resources, LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Yates, Seven Rivers, Grayburg, Queen.
Its 2 leases have reported 4.38M barrels of oil and 3.63M mcf of gas since April 2016, last reporting in July 2026. The leases carry 16 wells, so these are lease totals, not this well alone.
