Yturria #20 (API 42-489-31263) is a well in Willacy County operated by Texas Oil And Gas Operating LLC, completed June 18, 2014.

The RRC has issued one drilling permit (amended once), issued December 29, 2011, permitted to 10,500 ft.

It was permitted by Risco La Sara Operations, LLC and has since transferred to Texas Oil And Gas Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Miocene (undifferentiated), Catahoula, No 40 Sand.

Its 3 leases have reported 23.7K barrels of oil and 8.62K mcf of gas since July 2012, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
