Simulating stress-dependent fluid flow in a fractured core sample using real-time X-ray CT data

Kling, Tobias; Huo, Da; Schwarz, Jens-Oliver; Enzmann, Frieder; Benson, Sally; Blum, Philipp

Abstract:
Various geoscientific applications require a fast prediction of fracture permeability for an optimal workflow. Hence, the objective of the current study is to introduce and validate a practical method to characterize and approximate single flow in fractures under different stress conditions by using a core-flooding apparatus, in situ X-ray computed tomography (CT) scans and a finite-volume method solving the Navier-Stokes-Brinkman equations. The permeability of the fractured sandstone sample was measured stepwise during a loading-unloading cycle (0.7 to 22.1MPa and back) to validate the numerical results. ... mehr
