“…The observation of dissolution-driven particle migration along a possible CO 2 leakage pathway made by Newell and Carey (2012) supports the findings of our current study, thereby helping to make the case for inclusion of particle transport into future reactive transport simulations assessing CO 2 leakage risk. An excellent example of simulated particle transport and permeability reduction relevant to CO 2 sequestration has been presented by Sbai and Azaroual (2011), although for a porous medium rather than for a fractured caprock, and not due to dissolution-induced particle mobilization. Accounting for potential mechanical closure of the fracture following the approach of the thermal-hydrologicmechanical-chemical modeling employed for the study of geothermal reservoirs (e.g., Taron and Elsworth, 2009) should also lead to more robust CO 2 leakage risk assessments.…”

Geochemical reactions may alter the permeability of leakage pathways in caprocks, which serve a critical role in confining CO 2 in geologic carbon sequestration. A caprock specimen from a carbonate formation in the Michigan sedimentary Basin was fractured and studied in a high-pressure core flow experiment. Inflowing brine was saturated with CO 2 at 40°C and 10 MPa, resulting in an initial pH of 4.6, and had a calcite saturation index of -0.8. Fracture permeability decreased during the experiment, but subsequent analyses did not reveal calcite precipitation. Instead, experimental observations indicate that calcite dissolution along the fracture pathway led to mobilization of less soluble mineral particles that clogged the flow path. Analyses of core sections via electron microscopy, synchrotron-based X-ray diffraction imaging, and the first application of microbeam Ca K-edge X-ray absorption near edge structure, provided evidence that these occlusions were fragments from the host rock rather than secondary precipitates. X-ray computed tomography showed a significant loss of rock mass within preferential flow paths, suggesting that dissolution also removed critical asperities and caused mechanical closure of the fracture. The decrease in fracture permeability despite a net removal of material along the fracture pathway demonstrates a nonintuitive, inverse relationship between dissolution and permeability evolution in a fractured carbonate caprock.

“…The non-hydrodynamic forces considered in this model includes the unretarded van der Waals interaction (Masliyah and Bhattacharjee 2005;Elimelech et al 1995) and the EDL interactions. Equation 3 is commonly referred to as the convection-diffusion-migration (C-D-M) equation Masliyah and Bhattacharjee 2005;Nazemifard et al 2006a;Sbai and Azaroual 2011). This study analyzes transport of dilute suspensions such that particle-particle interactions can be neglected.…”

“…Lab-on-chip (LOC) systems (Felten et al 2008), flow of biomolecules in microchannels and microcapillaries (Waghmare and Mitra 2010a), porous media flows (Sbai and Azaroual 2011), chromatographic analysis (Bernate and Drazer 2011), and membrane separations (Das et al 2003;Bacchin et al 2011) are some of the examples of such systems in which particle transport in micro and nanochannels is ubiquitous. In most cases, the walls of these microchannels are physically and chemically heterogeneous which are either naturally occurring in these systems (Zhu et al 2008) or might be induced due to fabrication procedures (Rawool et al 2006).…”

An Eulerian model (convection-diffusionmigration equation) to evaluate particle transport in patchy heterogeneous cylindrical microchannels is presented. The objective of this model is to capture the effect of surface chemical heterogeneity on deposition and particle transport in cylindrical microchannels with fully developed Poiseuille flow velocity profile. Surface heterogeneity is modeled as alternate bands of attractive and repulsive regions on the channel wall to facilitate systematic continuum type evaluation. The results indicate that particles tend to preferentially collect at the leading edge of the favorable sections and the extent of this deposition can be controlled by changing Peclet number. Also, it is shown that particles tend to travel further along the microchannel length for heterogeneous channels compared to homogeneously favorable channels. In addition, the study evaluates the effect of the frequency of these stripes on the transport behavior and provides the average collection rate depending on favorable surface coverage fraction. This analysis shows how the existing microchannel/capillary transport models could possibly be modified by incorporating surface interactions and chemical heterogeneity.

“…On the other hand, Izgec et al [23] found that CO 2 injection into carbonate aquifers simulated using CMG's STARS could result in permeability reduction as well as improvement depending on the balance between mineral dissolution and precipitation. Furthermore, Sbai and Azaroual [24] found that CO 2 injection could in some circumstances cause particulates to clog reservoir pores leading to a permeability reduction and injectivity decline near the injection well.…”

A 100,000 t/year demonstration project for carbon dioxide (CO 2 ) capture and storage in the deep saline formations of the Ordos Basin, China, has been successfully completed. Field observations suggested that the injectivity increased nearly tenfold after CO 2 injection commenced without substantial pressure build-up. In order to evaluate whether this unique phenomenon could be attributed to geochemical changes, reactive transport modeling was conducted to investigate CO 2 -water-rock interactions and changes in porosity and permeability induced by CO 2 injection. The results indicated that using porosity-permeability relationships that include tortuosity, grain size, and percolation porosity, other than typical Kozeny-Carman porosity-permeability relationship, it is possible to explain the considerable injectivity increase as a consequence of mineral dissolution. These models might be justified in terms of selective dissolution along flow paths and by dissolution or migration of plugging fines. In terms of geochemical changes, dolomite dissolution is the largest source of porosity increase. Formation physical properties such as temperature, pressure, and brine salinity were found to have modest effects on mineral dissolution and precipitation. Results from this study could have practical implications for a successful CO 2 injection and enhanced oil/gas/geothermal production in low-permeability formations, potentially providing a new basis for screening of storage sites and reservoirs.
