Lopez #1 (API 42-131-39364) is a well in Duval County operated by Rattlesnake Operating CO LLC, completed May 30, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued March 6, 2013, permitted to 2,700 ft.
It was permitted by Sanchez Oil & Gas Corporation and has since transferred to Rattlesnake Operating CO LLC on the wellbore schedule.
Completion filings report 4 formation tops, including 1st Mirando, 2nd Mirando, 3rd Mirando, 4th Mirando.
Its lease has reported 22.4K barrels of oil since June 2013, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
