Fracture network can be commonly found or produced in many natural or damageable porous media, such as reservoirs, brittle materials and soil. Thus, fracture network and fractured porous media as well as their transport properties have received great attentions in many fields. Fractures are usually extended in length and aperture to form complex fracture network under some external conditions....
Permeability is one of the most important petrophysical parameters for reservoir characterization, completion design and production prediction, etc. However, due to the strong heterogeneity, poor pore structure, extremely low porosity and complicated minerals types in shale gas reservoirs, it is challenges for estimating the permeability accurately.
In this paper, we present a method for...
We study the in situ measured distributions of contact angles and curvatures within mm-size X-ray tomography images of rock samples from a producing
hydrocarbon carbonate reservoir imaged after wateflooding [1]. We analyse
their spatial correlation on a pore-by-pore basis using automated methods for
measuring contact angles [2], a new method for measuring curvatures, and by
performing pore...
Most commonly used numerical models of unsaturated porous media flow use a single capillary retention function which is specified at the start of the model run and alters capillary pressure only as a function of saturation. However, changes in porosity are common in geologic and industrial applications across a wide range of time scales. Consequently, numerical models of unsaturated media...
Drying of porous media is of significant importance in many fields ranging from hydrology and agriculture, to industrial applications, e.g., food sciences and chemical engineering. The drying process depends on both the external atmospheric conditions and structure of the porous medium. Previous research has shown that hydrogel produced by plant seeds/roots or bacteria can change the physical...
