Tracer Flow in a Fractured Geothermal Reservoir Model

Abstract

Tracer injection for identifying reservoir and transport parametersin geothermal sources has become an important procedure for desigtestshave been analyzed using convectiondiffusion equation to predict fracture size, width and probable thermal breakthrough times. The present study was conducted in a laboratory fractured reservoir model whose physical properties were known. The tracer, KI. breakthrough profiles were analyzed for different injection-production depth schemes. For different patterns different preferential flow paths existed which were then affected by flow through auxiliary paths. A correlation between heat and mass transport was used to define an apparent heat transfer coefficient for the flow.
