Condensate sampling

Definition

Condensate sampling is the process of collecting liquid samples from geothermal fluids after they have undergone phase separation, primarily to analyze their chemical composition. This method is essential for understanding the geochemistry of geothermal systems as it provides insights into the characteristics of the reservoir, including mineral content and fluid origin, helping in the assessment of resource viability and potential environmental impacts.
