Pore‐Scale Dissolution by CO 2 Saturated Brine in a Multimineral Carbonate at Reservoir Conditions: Impact of Physical and Chemical Heterogeneity
Journal ArticleDOI
Upscaling the porosity-permeability relationship of a microporous carbonate for Darcy-scale flow with machine learning.
TL;DR: In this paper, a micro-CT image of Estaillades limestone was divided into small 603 and 1203 sub-volumes and permeability was computed using the Darcy-Brinkman-Stokes (DBS) model.

Partial dissolution of carbonate rock grains during reactive CO2-saturated brine injection under reservoir conditions
TL;DR: In this article, the dissolution behavior in wettability-altered carbonate rocks at the nm-to µm-scale was investigated using X-ray micro-tomography and focused ion beam scanning electron microscopy (FIB-SEM) techniques.

CT scanning: patterns of use and dose
TL;DR: In most large hospitals in the United States CT scanning probably accounts for more than 10% of diagnostic radiology examinations and about two-thirds of the radiation dose, and most patients have multiple scan sequences.

Influence of Transport and Reaction on Wormhole Formation in Porous Media
TL;DR: The Damkohler number is shown to dictate the type of wormhole structure formed by systems with various degrees of transport and reaction limitations, and results from a 2-D network model and a 3-D physically representative network model agree qualitatively with experimental results and substantiate the existence of an optimum Damk Kohler number.
