West Ranch #6042 (API 42-371-37803) is a well in Pecos County operated by Occidental W TX Overthrust Inc., completed April 20, 2007.
The RRC has issued one drilling permit (amended 3 times), issued October 27, 2006, permitted to 9,000 ft.
It was permitted by Sandridge Energy, Inc. and has since transferred to Occidental W TX Overthrust Inc. on the wellbore schedule.
Completion filings report 4 formation tops, including Wolfcamp, Tesnus Ii Sand, Tensus Iii Sand, Tesnun Iii Sand.
Its 3 leases have reported 2.94K barrels of oil and 42.5K mcf of gas since April 2007, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
