- Federal Oil and Gas Leasing geospatial data is viewable on the Bureau of Land Management’s Mineral & Land Records System (MLRS) Research Map. Rocky Mountain Wild created a GIS snapshot of this data on 8/25/2025 and it is available as a zipped shapefile. Extracts for states in the Rocky Mountain Region are available in this Google Drive Folder.
- The Google Earth kmz data in the Google Drive Folder is color coded by held by production status: Red = held by actual production. Brown = held by allocated production. Purple = not held by production. Grey = production status unknown.
- Currently authorized leases spatial data extracted from the Bureau’s Oil and Gas Leases Feature Service as of 8/25/2025. Data was modified by Rocky Mountain Wild by extracting currently authorized leases, removing data with the poorest quality (including all parcels in Texas), changing the projection, and removing internal attributes.
