EGS Collab Experiment 1: Second Set Tracer Test Results

Dec 19, 2019
4.94 MB
Publicly accessible
The EGS Collab project is developing ~10-20 m-scale field sites where fracture stimulation and flow models can be validated against controlled, small-scale, in-situ experiments. The first multi-well experimental site was established at the 4850 level in the Homestake Mine in Lead,...

Development of a Downhole Tracer and pH Measurement Instrument for Application in Geothermal Wells

Sep 11, 2013
1.8 MB
Publicly accessible
Due the high temperature and pressure conditions found in geothermal wells, tracer studies designed to elucidate properties of geothermal reservoirs are traditionally conducted by pulling liquid samples from the wellhead. These samples are then sent off for analysis in a fixed lab...

Newberry EGS Demonstration: Well 55-29 Stimulation Data

Dec 08, 2012
273.53 MB
Publicly accessible
The Newberry Volcano EGS Demonstration in central Oregon, a 3 year project started in 2010, tests recent technological advances designed to reduce the cost of power generated by EGS in a hot, dry well (NWG 55-29) drilled in 2008. First, the stimulation pumps used were designed to ...
