Coupled hydromechanical modelling reveals surface uplift and subsidence risks in depleted hydrocarbon fields, highlighting UHS implications.

The study demonstrates significant surface uplift and subsidence during underground hydrogen storage operations.
Surface deformations were modeled using the Imperial College Geomechanics Toolkit, producing accurate reservoir pressure distributions.
The numerical implementation aligns well with classical models, validating the findings through established analytical solutions.
Understanding these ground deformations supports infrastructure safety in regions utilized for hydrogen storage.

Burtonshaw et al. (2025) studied this question.
