About this data
Wyoming Oil and Gas Conservation Commission's field registry, its well completions, and the volumes operators filed against the field on form 2, through Aug 2026. 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.
