Ector County · Dora Roberts (Consolidated) field · Producing · Vertical
Dora Roberts Ranch Unit #1809 (API 42-135-40811) is a well in Ector County operated by Continental Resources Inc., completed April 17, 2011 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued February 9, 2011, permitted to 10,400 ft.
It was permitted by Oxy USA Wtp LP and has since transferred to Continental Resources Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Wolfcamp, Strawn.
Its lease has reported 8.26M barrels of oil and 39.5M mcf of gas since October 1995, last reporting volume in April 2026. The lease carries 244 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Sep 17, 2013. Neutron. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
