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