Please join us from the comfort of your home or office for instructor-led, hands-on training on how you can use The Geochemist's Workbench® software to create quantitative models of multicomponent reaction processes in isothermal and polythermal geochemical systems.

This workshop will be of interest to users and potential users of the Standard and Professional versions of the GWB 2022 software.

The workshop will be presented as a fully interactive, instructor-led online meeting for three consecutive half-days, from 08:00 to 11:30 CST (13:00 to 16:30 UTC).

What you will learn. Following a fully hands-on format, you will learn all the ins and outs of this advanced toolset. Specific topics covered include:

  • Reaction in multicomponent systems
  • Geochemical buffers
  • Acidity and alkalinity
  • Acid drainage and wallrock buffering
  • Fluid mixing and scaling
  • Waste injection wells
  • Evaporation
  • Geothermometry
  • Creating phase diagrams with Phase2

Prerequisites: There are no advance requirements for this course, but we suggest you acquaint yourself with how to configure the GWB apps to model speciation and surface complexation.

Thank you for the GWB workshop—it was perfect! The tasks made the learning process really easy.

The [Johannesburg] workshop was good and quite informative, I'll be attending the one that you'll hold in Cape Town in 2016.

The perfect mix of lecture, background stories, knowledge, insights, and hands-on software exercises.

Before the workshop

As the workshop date approaches, please take note of the following:

  • About a week ahead of the workshop, we will send you a free 30-day license to The Geochemist's Workbench® 2022 Professional, along with the workshop schedule and two pdf files.
  • Please make sure GWB 2022 Standard or Professional is installed and activated on a computer running MS Windows before joining the workshop.
  • The first pdf file holds the complete set of PowerPoint slides to be shown by workshop instructors, in chronologic order, for your reference during and after the workshop.
  • We recommend you print and spiral bind the second pdf file, containing the workbook you will use to complete hands-on exercises.
  • We think you will be happiest if you have two computer screens available. That way, you will be able to take part in the workshop on one screen, while you use the other to run the software.
