Giesenschlag-Hensz Unit #1 (API 42-051-33065) is a plugged horizontal well in Burleson County, plugged April 16, 2012, last operated by Silver Oak Operating LLC.
The RRC has issued one drilling permit (amended once), issued May 4, 1990, permitted to 10,794 ft.
It was permitted by Christico Petroleum Company and has since transferred to Silver Oak Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Austin Chalk.
Its 2 leases have reported 10.8K barrels of oil and 269K mcf of gas since January 1993, last reporting in August 2012. The leases carry 2 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Christico Petroleum Company; the EWA schedule now lists a different operator.
