Experimental study of heat transport in fractured network
نویسندگان
چکیده
Fractured rocks play an important role in transport of natural resources through subsurface systems. In recent years, interest has grown in investigating heat transport by means of tracer tests, driven by the important current development of geothermal applications. Many field and laboratory tracer tests in fractured media show that fracture matrix exchange is more significant for heat than mass tracers, thus thermal breakthrough curves are strongly controlled by matrix thermal diffusivity. In this study, the behaviour of heat transport in a fractured network, at bench laboratory scale, has been investigated. © 2015 The Authors. Published by Elsevier Ltd.

Coupling Geomechanics and Transport in Naturally Fractured Reservoirs
Large amounts of hydrocarbon reserves are trapped in naturally fractured reservoirs which arechallenging in terms of accurate recovery prediction because of their joint fabric complexity andlithological heterogeneity. Canada, for example, has over 400 billion barrels of crude oil in fracturedcarbonates in Alberta, most of this being bitumen of viscosity greater than 106 cP in the GrosmontFormat...

Heat transfer fluids have inherently low thermal conductivity that greatly limits the heat exchange efficiency. While the effectiveness of extending surfaces and redesigning heat exchange equipments to increase the heat transfer rate has reached a limit, many research activities have been carried out attempting to improve the thermal transport properties of the fluids by adding more thermally c...
