"The natural gas storage in salt caverns requires faster injection cycles / racking due to the increasing \r\ndynamics of the energy market. These cycles induce rapid changes in the internal pressure of the stored \r\ngas causing important temperature changes that can damage the rock salt mass. Several theoretical \r\nstudies have been conducted to estimate this type of damage (Brouard et al, 2011; Sicsic and Berest, \r\n2014). To experimentally observe this damage, the Solution Mining Research Institute (SMRI) has \r\ncofounded the Starfish project between 2013 to 2016 and led by Storengy in partnership with the Ecole \r\ndes Mines de Paris, the Salins du Midi and INERIS. The main objective of this project was to initiate and \r\ncharacterize the damage by purely thermal stresses at the surface of a large bloc of salt partially slotted \r\nin a rock mass of the salt Mine of Varangéville (France). This was to determine the type of failure \r\nmechanism involved, the nature and extent of the cracks induced, as well as amplification of the damage \r\nof the solid mass with repeated cooling cycles. \r\nThe salt being favorable to the generation of Acoustic Emissions (AE) and the propagation of the stress \r\nwaves, the acoustic monitoring method has been chosen to follow the impact of the salt cooling. In \r\naddition to thermal and mechanical sensors, an acoustic monitoring device consisting of 16 ultrasonic \r\nsensors has been installed on the free surface and in boreholes. It enabled to record and locate a large \r\nnumber of AE (58426) with good accuracy (2.5 cm). Those AE can be correlated to the evolution of salt \r\nfracturing. Acoustic monitoring provided a very good insight in the physics of the damaging process."^^ . "2016" . . . . . . . . . . . . . . . . . . . . . "Hévin,"^^ . "Grégoire"^^ . "Hévin, Grégoire"^^ . .
