Resources
- Geospatial Data for currently authorized Federal Oil and Gas Lease Parcels
- 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 6/11/2024 and it is available as a zipped shapefile. Extracts for states in the Rocky Mountain Region are available in this Google Drive Folder.
- In Google Earth kmz data in the Google Drive Folder, Red = held by production. Purple = not held by production.
- Currently authorized leases spatial data extracted from the Bureau’s Oil and Gas Leases Feature Service as of 6/11/2024. 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, adding missing currently authorized parcels from recent sales in Wyoming (the majority of missing parcels with recent effective dates), adding attribute data from the BLM Land & Mineral System Reports as of 6/11 – 6/14/2024, and removing leases no longer authorized as of 6/11/2024.
