Exploration Basis
A conceptual model based on tracer testing was done to estimate swept volume and fluid velocity between pairs of production and injection wells.
A conceptual model was developed to analyze the results of tracer tests. The tracer moment analysis of Dixie Valley concluded that the reservoir can be considered a set of sub-parallel fractures with narrow apertures, long mean residence times, large surface areas, and adjacent damage zones that provide permeability. The tracers were injected in the center of the Dixie Valley Geothermal Field and recovered from the northeastern and southwestern production wells. This showed that there is no barrier to flow between the two areas of production wells. Groups of isolated fractures with different permeability are believed to connect pairs of injection and production wells.
