Yu et al. (2023): CO2 storage in chalks: What are we afraid of?

Tongtong Yu, Raoof Gholami, Arshad Raza, Kim Andre Nesse Vorland, Mohamed Mahmoud IN: International Journal of Greenhouse Gas Control 123, 103832, https://doi.org/10.1016/j.ijggc.2023.103832

This study attempts to evaluate the feasibility of CO₂ storage in carbonate chalk formations by focusing on changes in storage capacity (porosity) and injectivity (permeability) over time. A series of laboratory tests were carried out on Stevns Klint chalk from Denmark after exposure to CO₂ for 37 days at a fluid pressure of 15 MPa and a temperature of 50 °C.
