Numerical Modeling of Water-Rock-Gas Interactions and Natural Hydrogen Generation (G584)

Tutor

Dr. Eric C. Gaucher: Lavoisier H2 Geoconsult

Overview

In the rapidly evolving field of natural hydrogen, mastering geochemical modeling is a critical asset for any technical team.  This course will give participants the skills to undertake the numerical modeling of water-rock-gas systems and become familiar with the widely-used PHREEQC software package. You will receive debugged and optimized PHREEQC scripts and the specific LH₂G methodology for water chemistry quality control. This allows your team to save weeks of in-house development and avoid costly modeling errors.

Duration and Logistics

Classroom version: A 4-day course including case studies, exercises, and practical work on a variety of waters and H₂ generation systems. The exercises become more complex to allow for a step-by-step approach. The course can be given at your office, or for those wanting an out-of-office experience in Europe, the course can be delivered in Chamonix, France.

Level and Audience

Intermediate. The course is largely aimed at geoscientists, hydro-geochemists, hydrogeologists or process engineers wishing to acquire skills in geochemical numerical modeling. You will be required to have a basic knowledge of chemistry, geochemistry and fundamental notions of thermodynamics.

Objectives

You will learn to: 

1. Evaluate water chemistry and correction of the chemical composition.
2. Calculate the speciation of an aqueous solution and simulate water/rock/gas interactions in open or closed batch systems.
3. Model the evolution of fluid composition as a function of temperature, pressure and salinity.
4. Assess the chemical composition of a fluid during dissolution/precipitation of solid phases.
5. Characterize how hydrogen is generated from various rock types.
