Abstract
Process for destroying a rigid thermal insulator obtained in particular by a process of the sol-gel type and positioned in a confined space, the process comprising the stage of introducing a dissolving liquid into the confined space in order to convert the insulator into a liquid phase. The process applies in particular to destroying an insulating jacket positioned in the annular space of an oil well.
