Andrews County · Fullerton field · Producing · Vertical
Fullerton Clearfork Unit #7220 (API 42-003-47267) is a well in Andrews County operated by Hilcorp Energy Company, completed May 5, 2016 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 17, 2015, permitted to 7,427 ft.
It was permitted by Xto Energy Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 10 formation tops, including Yates, Seven Rivers, Queen, Grayburg.
Its lease has reported 77.4M barrels of oil and 65.6M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 1,406 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Mar 26, 2019. Cement bond. 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.
