Bastrop County · Yoast field · Vertical
Yoast #5 (API 42-021-80040) is a plugged well in Bastrop County, plugged May 3, 2002, last operated by Hellums Harold.
The RRC has issued one drilling permit, issued September 24, 2008, permitted to 1,630 ft.
It was permitted by Cibolo Energy Operating, Inc. and has since transferred to Hellums Harold on the wellbore schedule.
Completion filings report one formation top, including Serpentine.
Its 2 leases have reported 12.9K barrels of oil and 109 mcf of gas since January 1993, last reporting in July 2026. The leases carry 13 wells, so these are lease totals, not this well alone.
