文摘
- •
A semi-analytical correlation of the fracture aperture change induced by cold water injection has been derived. The correlation is of practical usage.
- •
The correlation has been implemented in a parallel geothermal simulator to conduct fully coupled thermal-hydraulic-mechanical simulation.
- •
The results predicted by the model has been used to qualitatively explain the increase of injectivity of cold water injectors and to predict the permeability variation in Cooper Basin.
