Development of geothermal energy sources is an important contribution to ensure the "green shift" from fossil fuels to more sustainable sources of energy. Currently, most geothermal wells operate at temperature range of 150 - 300⁰ C, but development of super-high temperature geothermal reservoirs...

Leakages of greenhouse gases, such as methane and carbon dioxide from wells, may have considerable environmental consequences. Although much emphasis is currently put on understanding well barrier failures, and thus, preventing well leakages, especially for an important barrier material as cement...

Annular cement sheath is considered to be one of the most important barrier elements in the well, both during production and after well abandonment. It is however well-known that mechanical damage to the cement sheath might result in leakage pathways, such as microannuli and radial cracks, and thus...

Cement sheaths are among the most important barrier elements in petroleum wells. However, the cement may lose its integrity due to repeated pressure variations in the wellbore, such as during pressure tests and fluid injections. Typical cement sheaths failure mechanisms are formation of radial...

In permanently abandoned wells, cement plugs serve as a well barrier element that is essential for providing long-term zonal isolation. Poorly plugged wells may provide leakage pathways that pose risks to the surrounding environment. It is well known that the final quality of set cement is...
