A survey of existing and developing field permeability test methods was conducted to identify and specify capable methods to be used in feasibility investigations or performance monitoring for in situ leaching ore deposits. Geologic settings of leachable deposits are discussed, as well as representative techniques used for the in situ leaching operation. Subsurface investigation techniques including drilling, core recovery, and down-hole inspection methods relevant to field permeability investigations are discussed. Field experience is examined and capable field permeability test methods are identified. Specifications for test borehole preparation, test performance, and methods of analysis are given. The test methods are comparatively rated in a matrix with respect to costs, ease of use, and data effectiveness for a broad range of conditions. Well pump and packer test methods receive high ratings. Recommendations are made for needed developments in field permeability test methods and a comprehensive bibliography is included.
