Cooper O. R. -D- #1 (API 42-429-31134) is a plugged well in Stephens County, plugged November 5, 2013, last operated by T-N-T Engineering Inc..
The RRC has issued one drilling permit, issued August 7, 1978, permitted to 4,500 ft.
It was permitted by Atoka Gas & Oil, Inc. and has since transferred to T-N-T Engineering Inc. on the wellbore schedule.
Completion filings report one formation top, including Marble Falls.
Its 3 leases have reported 221 barrels of oil and 59.3K mcf of gas since January 1993, last reporting in November 2013. The leases carry 5 wells, so these are lease totals, not this well alone.
