Permit surface location from the RRC GIS record, in Upton County.
Only the permit record exists for this well so far, here and in the RRC's wellbore query. Completion reports, formation tops, lease production, and the scanned filings appear once the operator files a completion report, typically months after drilling. Petrora refreshes the wellbore file weekly, so a filing from the last few days may reach the RRC before it shows here. How long each source takes →
