Journal Article: Tracer Testing at Dixie Valley, Nevada, Using Pyrene Tetrasulfonate Amino G, and Fluorescein

Abstract
A series of four tracer tests was recently conducted at the Dixie Valley, Nevada, geothermal reservoir in order to determine fluid-flow processes and to evaluate candidate tracers for use in hydrothermal systems. These tests have resulted in the first successful use of the compounds amino G and pyrenetetrasulfonate as tracers in a geothermal reservoir. The tracer candidates were subjected to simulated hydrothermal conditions in laboratory reactors at temperatures as high as 300°C in order to determine their thermal stabilities. They were next injected as pulses into the target injection wells. Fluids from the surrounding production wells were then sampled and analyzed in order to determine injectate flow patterns. The tracer data indicate that injected fluids flow only to a cluster of production wells in the south-central portion of the field; no tracer was produced in the producers located in the northeast section of the reservoir. Tracer returns from fluids injected into one of the wells indicate a much shorter residence time and a more heterogeneous flow pattern than traced fluids from the other three injectors
