Enhanced Geothermal Systems (EGS) Well Construction Technology Evaluation Report

Polsky, Yarom P.; Knudsen, Steven D.; Raymond, David W.

This report provides an assessment of well construction technology for EGS with 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 are likely to enhance prospects for EGS viability and improve overall economics.
