A debate rages as to whether abandoned oil and gas wells have to be sealed to prevent
methane leakage–a potent greenhouse gas–or whether the valuable infrastructure can be …

Supercritical geothermal systems are very high-temperature geothermal systems that are
located at depths near or below the brittle–ductile transition zone in the crust where the …

The investigation of the mechanical properties of hot dry rock (HDR) is of great significance
to the development of deep geothermal energy. However, the effects of thermal-mechanical …

We performed a series of hydraulic stimulations at 1.1 km depth in the Bedretto underground
laboratory, Switzerland, as part of an overall research strategy attempting to understand …

Enhanced geothermal systems (EGS) are engineered reservoirs that have been stimulated
to extract efficiently heat from low permeability hot rock. Generating efficient hydraulic …

Hot dry rock is an almost inexhaustible source of geothermal energy. Since the first attempt
to extract thermal energy from hot dry rock in America in the 1970s, successive studies have …

In order to achieve the goal of carbon neutrality in the energy sector and promote
sustainable economic development, it is critical to expand the depth of geothermal …

ABSTRACT Enhanced Geothermal Systems (EGS) development will require an ability to
accurately predict the flow rates and temperatures of the production wells over time. While …

Well planning for every drilling project includes cost estimation. Maximizing the rate of
penetration (ROP) reduces the time required for drilling, resulting in reducing the expenses …

This paper explores the potential of carbon dioxide as a working fluid in geothermal
systems, emphasizing its dual role in enhancing energy efficiency and contributing to carbon …
