A Saturation-Constrained Four-Phase Acoustic Screening Model for Shallow Gas-Bearing Permafrost: Coupled Effects of Ice Cementation, Gas Saturation, and Pore Pressure

Shallow free gas trapped within or beneath polar permafrost can be destabilized by drilling-induced thermal and pressure perturbations, but its acoustic response is difficult to separate from variations in lithology and freezing state. This study develops a saturation-constrained...
