Overview

Randomized trial investigates permeability changes in low-permeability formations, suggesting corrective factors for accurate predictions.

Key Points

  • This research aims to understand how shear displacement and confining pressure affect fluid flow in rough microfractures.
  • Reconstructed a rough microfracture surface using micro-CT imaging and image-processing techniques.
  • Conducted numerical simulations with the finite element method to analyze fluid flow under varying conditions.
  • Assessed the impact of shear deformation and confining pressure on permeability evolution.
  • Enlarged aperture bands created preferential flow paths, enhancing channelization in sheared microfractures.
  • Confined pressure caused gradual mechanical closure and a significant decrease in permeability.
  • The corrected cubic law improved permeability predictions by accounting for aperture variability and confining effects.
