Abstract

This dataset comprises 47 fluid samples from 11 geothermal sites (Germany, Austria, Iceland, Turkey, Netherlands, Belgium, French West Indies). The samples were collected within the REFLECT project (Redefining geothermal properties at extreme conditions to optimize future geothermal energy extraction). The focus with these analyses were on the organic compound composition of the fluids, since they are rarely included in the analyses of fluids taken from geothermal power plants. Understanding the organic compound composition of geothermal fluids might help to better understand chemical reactions within the fluids and might help to mitigate problems that arise with the operation of a geothermal power plant such as mineral precipitation (scaling) and corrosion of the casing and pipes.

Methods

The samples were taken by the onsite project partners and sent to GFZ for the analyses. Generally, the fluid samples were taken at the surface instalments and remained untreated after sampling (otherwise given as remark in the datasheet). Sampling bottles were rinsed and flushed with the fluids prior to filling them up. Sampling volumes ranged from 250-500 ml per sample.

        CharacterString: The samples were taken by the onsite project partners and sent to GFZ for the analyses. Generally, the fluid samples were taken at the surface instalments and remained untreated after sampling (otherwise given as remark in the datasheet). Sampling bottles were rinsed and flushed with the fluids prior to filling them up. Sampling volumes ranged from 250-500 ml per sample.
