Numerical Modeling for Hydraulic Fracture Prediction

Apr 26, 2016
1.1 MB
Publicly accessible
Numerical modeling on fused silica cylindrical materials for predicting overpressures required to fracture an homogeneous pure (surrogate) material with known mechanical properties similar to igneous rock materials and later compare these values to experimental overpressures obtai...

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 ...
