This paper evaluates current and historical drilling and completion costs of oil and gas wells
and compares them with geothermal wells costs. As a starting point, we developed a new …

This Handbook is a description of the complex process that comprises drilling a geothermal
well. The focus of the detailed Chapters covering various aspects of the process (casing …

The goal of this study was to characterize the uncertainty associated with the cost of drilling
and completion of geothermal wells. Previous research and publications have produced …

Wellbore drilling for any resource extraction—and particularly for EGS—is subject to many
uncertainties, ranging from those related to geology to those related to the drilling …

Abstract Thermal Spallation Drilling (TSD) is widely applied in the exploration and
development of oil, gas, and geothermal resources. Flake-like spalls (or particles) are often …

ABSTRACT The publication of “The Future of Geothermal Energy” in the fall of 2006 brought
renewed interest and focus to work on Engineered Geothermal Systems (EGS) in the US …

The perspectives of future development of geothermal power plants, mainly of small size for
the exploitation of medium–low temperature reservoirs, are discussed and analyzed in the …

The focal objective of this work is to calculate the energy consumption for constructing the
EGS (Enhanced Geothermal Systems) wells, to examine the energy (heat and power) …

In this work we have optimized the operation of a geothermal facility. Benzene, toluene and
cyclohexane are selected as candidate fluids based on previous studies. We formulated a …

In this chapter, utilization of deep geothermal energy as an economically viable source of
energy for district heating (DH) systems is discussed. An overview of enhanced geothermal …
