Jyoti and Haese, 2019, "The transition from face dissolution to wormhole formation in a heterogeneous limestone based on the distribution of local dissolution rates"
The findings from the dataset presented here are described in the paper titled "The transition from face dissolution to wormhole formation in a heterogeneous limestone based on the distribution of local dissolution rates" by Apoorv Jyoti and Ralf. R. Haese from the Peter Cook Center for CCS Research at the University of Melbourne. A multicomponent reactive transport model at the pore-scale in combination with a flow-through experiment with intermittent high-resolution imaging of the pore network geometry is used to better understand the formation of dissolution patterns in porous limestone. The 3D images of the pore network were used for reactive-transport simulations to derive the distribution of local dissolution rates. The model was validated through the comparison of experimental and integrated calcite dissolution rates derived from simulations. The image-based change in pore geometry was limited to less than 3 mm from the inflow of acid due to the rapid acid neutralization from calcite dissolution. The dataset consists of three parts: 1) Raw image data from the micro-CT scanner, 2) Chemical analysis of the effluent presented in an excel file, 3) The three reactive transport models at T0, T2, and T4, consisting of the input files for COMSOL and PhreeqC.
