Time for Geochemistry

A productive geochemical modelling framework based on PHREEQC.

The ultimate Phreeqc

GibbsStudio is the tool that every PHREEQC (USGS geochemical code) user needs. It allows you to run PHREEQC models in a productive graphical environment.

GibbsStudio provides automatic parameter calibration, quantification of uncertainty, sensitivity analysis and predominance plots.

GibbsStudio reduces the time spent on postprocessing and allows you to focus on modelling.


Productive environment

Save time in preprocessing and posprocessing and have more time for geochemistry.

Have a structured overview of your model with the hierarchical relational tree viewer that allows you to change your simulation settings with a single click.
Worried about your existing PHREEQC models? Import PHREEQC models and databases without effort.
Easily change the input source for your model or plots and update your results.
Define your own parameters using mathematical expressions.
