Abstract

The specific area of the contact surface between fractures and rock matrix, that has an important role in solute and heat transport in fractured-porous reservoirs, is not properly captured by hydraulic and geophysical tests, nor by flow-path tracings in highly dispersive flow fields. A single-well tracing method that increases the sensitivity of tracer breakthrough curves with regard to the contact-surface area parameter is described, with its first application in deep (geothermal) reservoirs in Germany.
