NOTE: EWG's estimates of leases that are currently producing oil or gas are constrained by the accuracy of information in BLM's Land and Mineral Records 2000 database, and may represent an overestimate. We have identified cases for which BLM has failed to enter the data necessary to identify particular leases on which production has ceased. An EWG request for more accurate production data is currently being processed by the Department of the Interior.
