Cowden Elliott F. -A- #166W (API 42-135-34374) is a plugged well in Ector County, plugged August 7, 2023, last operated by Occidental Permian Ltd..
The RRC has issued one drilling permit, issued October 6, 1983, permitted to 9,200 ft.
It was permitted by Amoco Production Company and has since transferred to Occidental Permian Ltd. on the wellbore schedule.
Completion filings report one formation top, including Canyon.
Its lease has reported 1.51M barrels of oil and 631K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 53 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received May 15, 2019. Neutron, Temperature. 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.
Open the RRC's log search for this well ↗| Logas described | Files | Intervalft, as filed | Datereceived | SizeMB |
|---|---|---|---|---|
| NeutronSpans Canyon | TIFF | 0 to 9,256 | May 15, 2019 | 15.7 |
| Temperature Survey | TIFF | 3,900 to 5,000 | May 7, 2019 | 18.0 |
"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.
