New Trapping Mechanism in Carbon Sequestration
Abstract The modes of geologic storage of $ CO_{2} $ are usually categorized as structural, dissolution, residual, and mineral trapping. Here we argue that the heterogeneity intrinsic to sedimentary rocks gives rise to a fifth category of storage, which we call local capillary trapping. Local capill...

| 520 | |a Abstract The modes of geologic storage of $ CO_{2} $ are usually categorized as structural, dissolution, residual, and mineral trapping. Here we argue that the heterogeneity intrinsic to sedimentary rocks gives rise to a fifth category of storage, which we call local capillary trapping. Local capillary trapping occurs during buoyancy-driven migration of bulk phase $ CO_{2} $ within a saline aquifer. When the rising $ CO_{2} $ plume encounters a region ($ 10^{−2} $ to $ 10^{+1} $m) where capillary entry pressure is locally larger than average, $ CO_{2} $ accumulates beneath the region. This form of storage differs from structural trapping in that much of the accumulated saturation will not escape, should the integrity of the seal overlying the aquifer be compromised. Local capillary trapping differs from residual trapping in that the accumulated saturation can be much larger than the residual saturation for the rock. We examine local capillary trapping in a series of numerical simulations. The essential feature is that the drainage curves (capillary pressure versus saturation for $ CO_{2} $ displacing brine) are required to be consistent with permeabilities in a heterogeneous domain. In this work, we accomplish this with the Leverett J-function, so that each grid block has its own drainage curve, scaled from a reference curve to the permeability and porosity in that block. We find that capillary heterogeneity controls the path taken by rising $ CO_{2} $. The displacement front is much more ramified than in a homogeneous domain, or in a heterogeneous domain with a single drainage curve. Consequently, residual trapping is overestimated in simulations that ignore capillary heterogeneity. In the cases studied here, the reduction in residual trapping is compensated by local capillary trapping, which yields larger saturations held in a smaller volume of pore space. Moreover, the amount of $ CO_{2} $ phase remaining mobile after a leak develops in the caprock is smaller. Therefore, the extent of immobilization in a heterogeneous formation exceeds that reported in previous studies of buoyancy-driven plume movement. | ||

In the cases studied here, the reduction in residual trapping is compensated by local capillary trapping, which yields larger saturations held in a smaller volume of pore space. Moreover, the amount of $ CO_{2} $ phase remaining mobile after a leak develops in the caprock is smaller. Therefore, the extent of immobilization in a heterogeneous formation exceeds that reported in previous studies of buoyancy-driven plume movement.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Carbon dioxide</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Heterogeneous</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Capillary pressure</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Leakage</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Local capillary trapping</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bryant, Steven L.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Sepehrnoori, Kamy</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Transport in porous media</subfield><subfield code="d">Springer Netherlands, 1986</subfield><subfield code="g">82(2009), 1 vom: 05.

New Trapping Mechanism in Carbon Sequestration |
| abstract |
Abstract The modes of geologic storage of $ CO_{2} $ are usually categorized as structural, dissolution, residual, and mineral trapping. Here we argue that the heterogeneity intrinsic to sedimentary rocks gives rise to a fifth category of storage, which we call local capillary trapping. Local capillary trapping occurs during buoyancy-driven migration of bulk phase $ CO_{2} $ within a saline aquifer. When the rising $ CO_{2} $ plume encounters a region ($ 10^{−2} $ to $ 10^{+1} $m) where capillary entry pressure is locally larger than average, $ CO_{2} $ accumulates beneath the region. This form of storage differs from structural trapping in that much of the accumulated saturation will not escape, should the integrity of the seal overlying the aquifer be compromised. Local capillary trapping differs from residual trapping in that the accumulated saturation can be much larger than the residual saturation for the rock. We examine local capillary trapping in a series of numerical simulations. The essential feature is that the drainage curves (capillary pressure versus saturation for $ CO_{2} $ displacing brine) are required to be consistent with permeabilities in a heterogeneous domain. In this work, we accomplish this with the Leverett J-function, so that each grid block has its own drainage curve, scaled from a reference curve to the permeability and porosity in that block. We find that capillary heterogeneity controls the path taken by rising $ CO_{2} $. The displacement front is much more ramified than in a homogeneous domain, or in a heterogeneous domain with a single drainage curve. Consequently, residual trapping is overestimated in simulations that ignore capillary heterogeneity. In the cases studied here, the reduction in residual trapping is compensated by local capillary trapping, which yields larger saturations held in a smaller volume of pore space. Moreover, the amount of $ CO_{2} $ phase remaining mobile after a leak develops in the caprock is smaller. Therefore, the extent of immobilization in a heterogeneous formation exceeds that reported in previous studies of buoyancy-driven plume movement. © Springer Science+Business Media B.V. 2009 |
