Flag Ranch D #4 (API 42-135-43504) is a well in Ector County operated by Raptor Resources Inc., completed June 19, 2017 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued March 29, 2017, permitted to 9,000 ft.

It was permitted by Capstone Natural Res II, LLC and has since transferred to Raptor Resources Inc. on the wellbore schedule.

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

Its lease has reported 68.4K barrels of oil and 136K mcf of gas since December 2014, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
