Abstract
The invention may provide a method and system of characterising at least one fracture in an enhanced geothermal system. The method comprises arranging two or more tracer sources with distinct tracer materials in known levels of a production well of the enhanced geothermal system. The method comprises injecting at least one tracer into the at least one fracture in the injection well, producing fluid in the production well, collecting samples of produced fluid and analysing the samples for the presence and/or concentration of tracers. Based on the presence and/or concentration of tracers in the samples estimating at least one characteristic of the at least one fracture.
