Fracture Transmissivity in Prospective Host Rocks for Enhanced Geothermal Systems (EGS) [PDF]
Geosciences, 2022 We experimentally determined the hydraulic properties of fractures within various rock types, focusing on a variety of Variscan rocks. Flow-through experiments were performed on slate, graywacke, quartzite, granite, natural fault gouge, and claystone samples containing an artificial fracture with a given roughness.

Overcoming challenges in the classification of deep geothermal potential [PDF]
, 2015 The geothermal community lacks a universal definition of deep geothermal systems. A minimum depth of 400 m is often assumed, with a further sub-classification into middle-deep geothermal systems for reservoirs found between 400 and 1000 m.

Enhanced Geothermal Systems (EGS) Well Construction Technology Evaluation Report [PDF]
, 2008 A synopsis of a report evaluating well construction technology for Enhanced Geothermal Systems (EGS) is presented. The assessment of well construction technology had two primary objectives: 1. Determining the ability of existing technologies to develop EGS wells. 2. Identifying critical well construction research lines and development technologies that
