Information Provided by Technique
Hydrological: Results can aid in the determination of fluid source regions and circulation pathways, and assist in determining the degree of mixing between different hydrothermal fluids.
Thermal: Certain elements exhibit high spatial correlation with high-temperature geothermal systems; Isotopic ratios can be used to characterize and locate subsurface thermal anomalies.
Fluid Lab Analysis:
Fluid lab analysis encompasses a broad array of techniques used for the analysis of water and gas samples. These analyses are used in a variety of disciplines to quantify the chemical components and properties of groundwater systems. In geothermal exploration and development, fluid analyses often provide a first look into the characteristics of a hydrothermal system, and are routinely used in ongoing monitoring of geothermal reservoirs.

Fluid lab analysis is routinely used in hydrology and geochemistry for the characterization of fluid samples, identification of contaminants, and to trace the migration of chemical species through reservoir systems. Fluid lab analysis encompasses several techniques, including isotopic analysis, major, trace element, and molecular analysis, and analysis of fluid inclusions trapped in hydrothermal minerals.

Use in Geothermal Exploration
Lab-based fluid analysis techniques are used throughout the lifetime of a geothermal project, from the early exploration stages through to monitoring of development wells. Fluid analysis provides data used for estimation of reservoir temperatures through various chemical and isotopic geothermometers, and allows investigators to use chemical and isotopic tracers to evaluate flow in hydrothermal systems. Gas analyses can also reveal information that can be used to distinguish the source of heat in a hydrothermal system (e.g. magmatic vs. deep subsurface conduits).
