TwoPhase Flow Within Porous Media Analogies: Application Towards CO2 Sequestration
Abstract
Geologic carbon dioxide sequestration (GCO2S) involves the capture of large quantities of CO2 from pointsource emitters and pumping this greenhouse gas to subsurface reservoirs (USDOE, 2006). The mechanisms of twophase fluid displacement in GCO2S, where a less viscous fluid displaces a more viscous fluid in a heterogeneous porous domain is similar to enhanced oil recovery activities. Direct observation of gasliquid interface movement in geologic reservoirs is difficult due to location and opacity. Over the past decades, complex, interconnected porethroat models have been developed and used to study multiphase flow interactions in porous media, both experimentally (Buckley, 1994) and numerically (Blunt, 2001). This work expands upon previous experimental research with the use of a new type of heterogeneous flowcell, created with stereolithography (SL). Numerical solutions using the VolumeofFluid (VOF) model with the same flowcell geometry, are shown to be in good agreement with the drainage experiments, where the defending fluid wets the surface. This computational model is then used to model imbibition, the case of the invading fluid preferentially wetting the surface. Low capillary flows and imbibition conditions are shown to increase the storage volume of the invading fluid in the porous medium.

The amount of CO2 that can be sequestered in deep brine reservoirs is dependant on fluidfluidsolid interactions within heterogeneous porous media. Displacement of an inplace fluid by a less viscous invading fluid does not displace 100% of the defending fluid, due to capillary and viscous fingering. This has been studied experimentally and numerically with the use of porethroat flow cells and porelevel models, respectively, in the last two decades. This current work solves the full NavierStokes and continuity equations in a random porethroat geometry using the Volume of Fluid (VOF) method. To verify that the VOF model can be accuratelymore »

Flow in Porous Media: Experiments and Simulations with Application to CO2 Sequestration
The amount of carbon dioxide that can be sequestered in reservoirs is dependent on fluidfluidsolid interactions within porous rock. Displacement of an inplace fluid by a less viscous invading fluid does not evacuate 100 percent of the defending fluid, due to capillary and viscous fingering. This has been studied over the past decades experimentally and numerically with porethroat flow cells and porelevel models, respectively. This current work examines immiscible twophase displacements within a novel flowcell and extends this experimental work with a computational fluid dynamics model within the same random porethroat geometry using the Volume of Fluid (VOF) method.

TwoPhase Flow within Geological Flow AnalogiesA Computational Study
Displacement of a viscous fluid in heterogeneous geological media by a less viscous one does not evacuate 100% of the defending fluid due to capillary and viscous fingering. This is of importance in geological flows that are encountered in secondary oil recovery and carbon dioxide sequestration in saturated brine fields. HeleShaw and pore/throat cells are commonly used to study this in the labratory. Numerical simulations of this flow phenomenon with porethroat models have been prevalent for over two decades. This current work solves the full NavierStokes equations of conservation within random porethroat geometries with varying properties to study the resultingmore » 
Flow in porous media II: The governing equations for immiscible, twophase flow
The Stokes flow of two immiscible fluids through a rigid porous medium is analyzed using the method of volume averaging. The volumeaveraged momentum equations, in terms of averaged quantities and spatial deviations, are identical in form to that obtained for single phase flow; however, the solution of the closure problem gives rise to additional terms not found in the traditional treatment of twophase flow. Qualitative arguments suggest that the nontraditional terms may be important when ..mu../sub ..beta..//..mu.. is of order one, and order of magnitude analysis indicates that they may be significant in terms of the motion of a fluidmore »
