Shows where there are potential commercial sources of natural gas trapped in formations with very low permeability to gas (not necessarily shale units). Hydraulic fracturing might be needed in order to exploit these resources.
Using a performance-based geological assessment methodology, we estimated mean volumes of 1,345 billion cubic feet of potentially technically recoverable gas and 168 million barrels of technically recoverable oil and natural gas liquids here.
Describes organizational process and field study used to estimate production capacity (mostly by artisanal miners) in the parts of the country likely to contain diamonds. We estimate a production capacity of 600,000 carats per year.
Presentation describing uses of rare earth elements, why they are important, where they occur and are produced, and aspects of the economics of production and consumption with emphasis on sites that might be developed for production.
