Chico Company #228A (API 42-383-37429) is a well in Reagan County operated by RP Operating L.L.C., completed May 4, 2012 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 12, 2011, permitted to 9,315 ft.
It was permitted by Fiml Natural Resources, LLC and has since transferred to RP Operating L.L.C. on the wellbore schedule.
Completion filings report 5 formation tops, including Spraberry, Dean, Wolfcamp, Canyon.
Its lease has reported 369K barrels of oil and 1.53M mcf of gas since December 2010, last reporting volume in April 2026. The lease carries 14 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Oct 29, 2014. Density, 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.
