Characterizing the Evolution of Trapped scCO2 Curvature in Bentheimer and Nugget Sandstone Pore Geometry

Characterizing the Evolution of Trapped scCO2 Curvature in Bentheimer and Nugget Sandstone Pore Geometry

During a Geologic Carbon Storage process, supercritical CO2 (scCO2) is subjected to a series of dynamic and static conditions where the relationship between pore geometry and the trapped scCO2 curvature remains to be established. To mimic the dynamic process, two sandstones, Bentheimer and Nugget, were subjected to two successive drainage and imbibition (D-I) cycles and X-ray computed tomography scanned at each residual state to capture the wettability evolu...

Uncertainty span for relative permeability and capillary pressure by varying wettability and spatial flow directions utilizing pore scale modelling

Uncertainty span for relative permeability and capillary pressure by varying wettability and spatial flow directions utilizing pore scale modelling

Relative permeability and capillary pressure are key properties within special core analysis and provide crucial information for full field simulation models. These properties are traditionally obtained by multi-phase flow experiments, however pore scale modelling has during the last decade shown to add significant information as well as being less time-consuming to obtain. Pore scale modelling has been performed by using the lattice-Boltzmann method directly on the digital rock models obtain... Read more

Analyzing the Relationship between Capillary Pressure, Saturation, and Interfacial Area for a Three-Phase Flow System in Porous Media

Analyzing the Relationship between Capillary Pressure, Saturation, and Interfacial Area for a Three-Phase Flow System in Porous Media

In this study, we examined the relationship between capillary pressure, saturation, and interfacial area for a three-phase flow system. Using x-ray microtomography we were able to capture high-resolution three-dimensional images of the flow system, from which the saturation, interfacial area, and capillary pressure were determined.

Multi-phase flow in porous media includes many instances of subsurface flow. Three-phase flow in particular is important in situations of enhanced oil recov... Read more

Pore‐Scale Experimental Investigation of Two‐Phase Flow Through Fractured Porous Media

Pore‐Scale Experimental Investigation of Two‐Phase Flow Through Fractured Porous Media

Understanding transport mechanisms that govern two-phase flow in fractured porous media has direct implications for natural and industrial processes such as extraction of hydrocarbons from fractured reservoirs, geologic sequestration of CO2, or fluid flow through aquifers.

We present the results of a systematic pore‐scale experimental investigation of two‐phase oil/brine flow through a miniature water‐wet, fractured sandstone core sample. X‐ray microtomography is employed to ge... Read more

Combining high-resolution with larger volume images for improved characterization of mudstone reservoirs

Combining high-resolution with larger volume images for improved characterization of mudstone reservoirs

Optimization of production from shale reservoirs requires understanding of rock properties over a range of scales.

Multiple imaging techniques can be combined to determine the nature, connectivity, and wettability of nano-scale pore systems as well as the underlying mineralogy and organic textures that control reservoir behavior and the propensity of the matrix to fail and to contain expulsion cracks. The current study demonstrates new capabilities in integrated multiscale and time-res... Read more
