A study of changes in deep fractured rock permeability due to coupled hydro-mechanical effects
Author(s): Figueiredo, B; Tsang, CF; Rutqvist, J; Niemi, A | Abstract: © 2015 Elsevier Ltd. This paper presents a numerical study of the hydro-mechanical behaviour of a fractured rock domain at 1000.… Expand
Upscaling of fracture hydraulics by means of an oriented correlated stochastic continuum model
 Two methods for upscaling hydraulics of fractured media are compared, namely, a classical fracture network based approach and a new enhanced stochastic continuum approach, the benefit of the… Expand
Coupled hydro-mechanical processes and fault reactivation induced by Co 2 Injection in a three-layer storage formation
Abstract The interaction between mechanical deformation and fluid flow in fault zones gives rise to a host of coupled hydro-mechanical processes fundamental to fault instability, induced seismicity,… Expand
A partially coupled, fraction-by-fraction modelling approach to the subsurface migration of gasoline spills.
The subsurface spreading behaviour of gasoline, as well as several other common soil- and groundwater pollutants (e.g. diesel, creosote), is complicated by the fact that it is a mixture of hundreds… Expand
Review: The state-of-art of sparse channel models and their applicability to performance assessment of radioactive waste repositories in fractured crystalline formations
Laboratory and field experiments done on fractured rock show that flow and solute transport often occur along flow channels. ‘Sparse channels’ refers to the case where these channels are… Expand
A regional-scale particle-tracking method for nonstationary fractured media
A regional scale transport model is introduced that is applicable to non-stationary and statistically inhomogeneous fractured media, provided that hydraulic flow, but not necessarily solute… Expand
Analysis of alternative push–pull-test-designs for determining in situ residual trapping of carbon dioxide
- Kristina Rasmusson, Maria Rasmusson, F. Fagerlund, J. Bensabat, Y. Tsang, A. Niemi

Carbon dioxide storage in deep saline aquifers is a promising technique to reduce direct emissions of greenhouse gas to the atmosphere. To ensure safe storage the in situ trapping mechanisms, resid… Expand
Flow dimension as an indicator of hydraulic behavior in site characterization of fractured rock.
We examine the possibility of using the flow dimension identified from constant pressure injection tests as a tool for characterizing the hydraulic conditions of fractured media. The data comes from… Expand

Understanding of the entrapment and dissolution behavior of dense non-aqueous phase liquids (DNAPLs) in single fractures is important for modeling contaminant flux generation from fractured sites.… Expand
Two‐phase flow in rough‐walled fractures: Comparison of continuum and invasion‐percolation models
 We present a systematic comparison study of simulating two-phase flow (drainage) in single heterogeneous fractures by using two fundamentally different approaches, namely, a continuum-based… Expand
