Hydraulic fracturing (HF) has become essential for extracting oil and gas from unconventional reservoirs and heat energy from hot dry rock masses. However, a paradox remains in the fracturing mode of HF: stress conditions predicted by elasticity theory suggest tensile fracturing, while shear fracturing is dominant in HF-related microseismicity (MS). This book resolves this paradox by reviewing the results of various laboratory and small-scale field experiments conducted by the author over nearly 40 years.
It explores the use of carbon dioxide (CO2) in HF as a method for geologic sequestration and demonstrates that CO2 can induce three-dimensional, sinuous cracks with numerous secondary branches, creating ideal pathways for heat, oil, and gas recovery. The author provides a detailed explanation of the fracturing mechanisms based on rock and fluid properties, particularly the use of supercritical (SC) CO2 as a fracturing fluid. Readers will benefit from a deeper understanding of HF processes and their applications for resource extraction and environmental management.
