Dear Colleagues,
We are pleased to announce that AquaNRG, an environmental and energy tech company in Houston, will host a "Geochemical and Reactive Transport Modeling Course for Geologic CO2 Storage" on July 7th, 2022. You could find further information about this course in the link below:

Following the successful CCUS workshop sponsored by Premier Oilfield Group at AAPG Conference, i.e. A Journey Through Carbon Captured Focused Core Analysis Program, and presentation by AquaNRG team on reactive transport modeling for CCS applications, this complimentary course will cover a comprehensive review of geochemical methods to build fluid-rock interaction models for CO2 injection/storage. Furthermore, in this course geochemical and 1D reactive transport models using USGS's powerful and open-source geochemical simulator i.e. PHREEQC will be demonstrated. This course has been designed for geoscientists and engineers interested in CO2 injection/storage modeling which is also outlined in EPA Class VI UIC Guideline regulatory documents.
About EPA Class VI Guidelines:
As you are aware of, "US Environmental Protection Agency (EPA)'s Federal Requirements Under the Underground Injection Control Program for carbon dioxide Geologic Sequestration Wells are codified in the U.S. Code of Federal Regulations [40 CFR 146.81 et seq.] and are referred to as the Class VI Rule. The Class VI Rule establishes a new class of injection well (Class VI) and sets minimum federal technical criteria for Class VI injection wells for the purpose of protecting underground sources of drinking water (USDWs)." EPA has provided a series of technical guidance documents designed to support owners or operators of Class VI wells and the UIC Program permitting authorities.
As suggested by EPA in these guidelines, reactive transport models play critical role in studying significant effects of geochemistry, and fluid-rock interactions while delineating the Area of Review (AoR):
"If an evaluation of potential geochemical processes suggests that long-term storage and confinement of carbon dioxide may be affected by changes in the injection formation and confining zone(s), the AoR delineation may need to account for geochemical reactions through the use of reactive transport models. EPA recommends the use of dynamic modeling for updating carbon dioxide storage capacity estimates. Periodic reevaluations of the storage capacity should be done in conjunction with reevaluations of the AoR. For example, estimates of carbon dioxide trapping mechanisms from reactive transport modeling will affect storage capacity estimates. Likewise, alterations in storage capacity estimates may lead to changes in operational parameters. Evaluations of storage capacity and operational parameters may especially need to be revisited in case of unexpectedly high pressure buildup within the injection formation or evidence of fluid displacement that may cause significant risk of endangerment to USDWs. "
