About this data

Wyoming Oil and Gas Conservation Commission (WOGCC), from its public database extracts. Status and type are in WOGCC's own words. Production and injection are what operators filed on form 2, by well and month; twelve-month figures end in Aug 2026, the last month whose filings are in. Locations are from the well's location plat and are approximate. The Commission's production file names each well's current operator on every month, so an operator's figures are those of the wells it operates today. Nothing is estimated.
