Surface location

No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

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 →
