Comments on "Predicting permeability changes with injecting CO2 in coal seams during CO2 geological sequestration: A comparative study among six SVM-based hybrid models" Science of the Total Environment, 705, 135941 (2020)

Sci Total Environ. 2020 Nov 20;744:139486. doi: 10.1016/j.scitotenv.2020.139486. Epub 2020 Jun 5.


In this study, some important mistakes related to model development process and missing information which should be carefully taken into account by the authors of the previous literature and other researchers are presented. Some important issues are presented to avoid propagation of similar mistakes in the scientific literature.

Keywords: CO2 sequestration; Coal seam; Permeability; Predictive model; SVM-based hybrid model.
