Operator of record and permit operator
A well's operator of record is the WOGCC's, and its permit operator is the one on its latest drilling permit; neither fills in for the other. Its wells of record are counted as its wells, with its live permits; a well it permitted that another operator runs, or that the WOGCC lists with no operator at all, is not. Each count opens the wells it counts. Transfers and operator numbers →

About this data
Wyoming Oil and Gas Conservation Commission (WOGCC). Big Muddy Operating LLC is identified by its operator. Well counts are the wells it is operator of record for today; volumes are what it filed under that number, through Aug 2026 for production and Aug 2026 for injection. 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.
