Whittenburg #9LS (API 42-135-43587) is a horizontal well in Ector County operated by Permian Resources Operating LLC, completed February 11, 2023 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued April 11, 2018, permitted to 11,000 ft.

It was permitted by Independence Resources Mgmt, LLC and has since transferred to Permian Resources Operating LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.

Its lease has reported 3.85M barrels of oil and 8.74M mcf of gas since February 2010, last reporting in July 2026. The lease carries 36 wells, so these are lease totals, not this well alone.
