Rio San Jacinto 38-43 D #243
Midland County · Spraberry (Trend Area) field · Shut In · Horizontal
Rio San Jacinto 38-43 D #243 (API 42-329-46418) is a horizontal well in Midland County operated by Diamondback E&P LLC, completed August 26, 2024 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued July 18, 2023, permitted to 9,402 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Santa Rosa, Rustler, Yates, Seven Rivers.
Its 2 leases have reported 2.9M barrels of oil and 9M mcf of gas since August 2023, last reporting in July 2026. The leases carry 17 wells, so these are lease totals, not this well alone.
