The Python scripts presented in this repository can simulate microbially induced calcium carbonate precipitation (MICP) experiments as reported in the work of Martinez et al (2013). Each python file simulates one experiment that is mentioned in the docstring at the top of each file. For the full description of each experiment, refer to the work of Martinez et al. (2013) and Martinez et al. (2014).

A geochemical solver called Phreeqc is used for geochemical calculations. Phreeqpy is a python interface for Phreeqc that is utilized here. Phreeqc handles various geochemical calculations using different keyword blocks. A keyword block is a code segment in the input file processed by Phreeqc. To develop a model for conducting MICP in a column, we utilized the following keyword blocks for specific purposes:

• Solution: for defining initial and inlet solutions.
• Rate: to define the rate of ureolysis and precipitation.
• Kinetics: to add the kinetics using rate equations to the solutions.
• Transport: to make a column with specific number of cells and initiate flow.
• Selected_Output: to collect output data.

The full description of each of the aforementioned keyword blocks is provided in the Phreeqc manual.
