Pilgrim Hot Springs, Alaska Geothermal Project

|Project Title||Pilgrim Hot Springs, Alaska|
|Project Type / Topic 1||Recovery Act: Geothermal Technologies Program|
|Project Type / Topic 2||Validation of Innovative Exploration Technologies|
|Project Description|| A combination of existing and innovative remote sensing and geophysical techniques will be used to site the two confirmation core holes. These include a suite of Landsat, Aster, and FLIR techniques using infrared radiation combined with a CSAMT/AMT resistivity survey, 4.5 m to 150 m temperature gradient holes, and 1980 convective heat loss calculations. These will be used in combination to determine the natural heat loss from the Pilgrim geothermal system and allow an order of magnitude estimate of the resource potential.
As part of this project the University of Alaska is proposing a new and innovative iterative method of digital processing of acquired thermal infrared data adapted from thermal data processing techniques successfully used to identify small and subtle coal mine fires and in volcanology research. This has been successfully attempted for a geothermal system with a discrete surface expression on one prior occasion by the project team. If this technique can be repeatedly shown to be effective at estimating the heat flow to the surface, it will provide a very low cost and fast method of measuring the natural heat loss for certain geothermal systems which can be used as an indication of its maximum possible electrical megawatt output potential.
|Objectives||Utilize remote sensing and ground based geophysical surveys to develop a preliminary conceptual model to site two NQ or HQ sized core holes.|
