Carbon Dioxide removal from air (CDR) combined with permanent solid storage can be
accomplished via carbon mineralization in ultramafic rocks in at least four ways: 1. Surficial …

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 paper presents an investigation into the suitability of abandoned wells in California for
Enhanced Geothermal Systems (EGS) and low temperature deep Borehole Heat Exchanger …

Drilling rate of penetration (ROP) prediction is an enormously important step to optimize
drilling controllable parameters. Therefore, numerous efforts have been done in order to …

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 …

With increasing costs, finite sources, and adverse environmental impacts of fossil fuels,
global attention has focused on develo** renewable and clean sources of energy …

First, the heat sources that can be used to power salinity gradient heat engines (SGHEs) are
explored. The waste heat sources included in this analysis are waste heat from the industry …

Using abandoned gas wells as geothermal resources for energy production is an effective
way to extract geothermal energy from geological formations. These abandoned wells have …

The province of Alberta has a high demand of thermal energy for both industrial and
residential applications. Currently, the vast majority of the heat used in these applications is …

Drilling parameters are analyzed here to improve forecasting of the rate of penetration
(ROP) in enhanced geothermal systems (EGSs). Data recorded during drilling a 4.2-km …
