Asche #98 (API 42-505-35227) is a well in Zapata County operated by Hilcorp Energy Company, completed July 12, 2005 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued February 24, 2005, permitted to 10,100 ft.
It was permitted by Houston Exploration Company, The and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including Perdido Unconformity, Top Perdido A, Top Perdido B.
Its 2 leases have reported 300 barrels of oil and 418K mcf of gas since May 2005, last reporting volume in April 2026. The leases carry 2 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 15, 2008. Resistivity. 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.
