EGS Collab Experiment 1: Time-series geochemistry data of the long-term circulation test

Published by Stanford University | Department of Energy | Metadata Last Checked: January 27, 2026 | Last Modified: 2025-02-17T18:17:55Z
This submission presents the weekly geochemistry data of the long-term flow test performed within EGS Collab Experiment 1 from early 2019 to early 2020. The fluids from each producing borehole/interval (PI, PB, PDT and PST) along with the injectate were sampled roughly weekly from April 2019 to January 2020 for geochemistry analysis. The geochemical measurement was part of a long-term microbial profiling project (see details in the PNAS paper linked below). Additional background and methodologies are available in the PNAS paper linked bellow.
