报告内容简介（Abstract）：
Permeability is the fundamental rate-limiting factor governing the performance of unconventional reservoirs, deep geothermal systems, and subsurface energy storage. However, current stimulation technologies remain largely empirical, focusing on fracture creation rather than control. This disconnect leads to unpredictable fracture networks, inefficient fluid flow, and long-term integrity challenges.
This presentation critically evaluates existing stimulation techniques, including hydraulic fracturing, supercritical CO₂ injection, foam-based stimulation, and thermal methods, and demonstrates their limitations in controlling fracture evolution under in-situ stress conditions. By integrating insights from rock mechanics, fluid–rock interactions, and energy-driven fracture processes, the talk reframes permeability enhancement as a problem of controlled energy delivery in the subsurface.
A novel framework based on time-dependent energy release is introduced, enabling regulated fracture initiation and propagation, and offering improved control over fracture density, orientation, and connectivity. This approach opens new opportunities for sustainable and efficient subsurface engineering across a wide range of applications, from hydrocarbon recovery to geothermal energy and hydrogen storage.
By shifting the paradigm from passive stimulation to active control, this work highlights the need for a new generation of technologies aimed at engineering permeability rather than merely inducing it.
