Rock mechanics is meeting the challenge of geo-energies
Résumé
The exploitation of geo-energies often leads to difficulties that rock mechanics helps to overcome. These essentially consist of
instability problems caused by changes in the state of stress, associated pore pressures, and temperature. Besides the classical
near field problem of wellbore stability, the changes can impact a larger scale, triggering earthquakes and inducing seismicity. In
this paper the current approaches envisaged to tackle these problems are briefly reviewed and discussed. Some extensions that
have been made possible thanks to the combination of new numerical techniques is outlined.
