Geomechanical modelling of underground gas storage (UGS) activities in an exhausted gas field

Category
Computer Modelling, Geomechanical Engineering
ABOUT THE PROJECT

This study, developed in cooperation with the University of Padova, is aimed at the numerical modelling of the geomechanical effects induced by the storage of natural gas in an underground exhausted field.

The geomechanical analysis is performed with the aid of a state-of-the-art 3D finite-element numerical model, developed by the M3E team, with the following objectives: (1) predict the land surface displacements over the field, (2) analyze the variation of the natural stress field induced by the field activities, and (3) analyze the possible activation of faults and fractures located in the proximity of the reservoir.
