Abstract:
A method for detecting the geometry of underground fractures comprising: introducing a filling material (14) into an underground fracture (11) to form a pack of filling material (14); transmitting an electromagnetic field into the fracture (11); detecting at least one reflected signal of the electromagnetic field transmitted; and processing the at least one detected signal to reconstruct the geometric and dimensional characteristics of the pack of filling material (14); wherein the electromagnetic field transmitted into the fracture (11) has a frequency comprised in the range of between 30 megahertz and 250 megahertz and in that said filling material is not added with any additives; and a system for implementing the aforementioned method.
