Exploration Activity: Core Analysis At Medicine Lake Area (Clausen Et Al, 2006)
|Exploration Activity Details|
|Location||Medicine Lake Area|
|Exploration Technique||Core Analysis|
A major challenge to energy production in the region has been locating high-permeability fracture zones in the largely impermeable volcanic host rock. An understanding of the fracture networks will be a key to harnessing geothermal resources in the Cascades. Medicine Lake site was selected for this study because of the extensive collection of core samples, lithologic, structural, geophysical and temperature data that are available. The sample collection totals about 15.8 km of core from 18 wells. Core samples are critical for the study because they allow characterization of fracture aperture, permeability, age relationships, and kinematics (e.g. Nemcok and Lisle, 1995; Nemcok and Gayer, 1996).
