Abstract
Tracer returns provide direct proof of fluid connections between different wells in a geothermal field. The tracer profile yields estimates for travel times and fluid recovery fractions between injection and production wells, and can provide strong constraints on assumed reservoir structure in numerical simulators. Analysis of tracer profiles is not always straightforward, due to uncertainties from secondary injection of tracer, and from assumptions about the
