This package includes the final technical report for the Play-Fairway project in Washington State. It includes all activities and reporting from phases 1, 2, and 3. The primary goal of this study is to develop a suite of tools and methods that help identify a ?fairway? where the three main aspects of a functioning geothermal system are most likely to be found and particularly focuses on developing these tools for use in an actively deforming magmatic arc where heat is associated with volcanic centers and permeability is provided by a network of suitably stressed active faults.
