    Dear Colleagues,

    Only 4 days left until AquaNRG's workshop on Geochemical and Reactive Transport Modeling of Geologic CO2 Storage" which will be held on April 21, 2023. If you are interested in the following workshop, we have a few more spots available:

    We are pleased to announce that 
    AquaNRG, energy tech company in Houston, will host its first hybrid workshop on "Geochemical and Reactive Transport Modeling of Geologic CO2 Storage" in 2023 on April 21st. You can find further information about this workshop in the link below:

    AquaNRG team organized 3 very successful workshops in 2022 including: 1) in-person workshop in partnership with Premier Oilfield Group at AAPG Conference, i.e.
    A Journey Through Carbon Captured Focused Core Analysis Program, and, 2) two hybrid online and in-person workshops held at Greentown Labs, Houston, Texas. 100+ professionals from 23 countries working in E&P, oilfield service companies, and leading research institutes attended these workshops. 

    This workshop encompasses a comprehensive review of geochemical methods to build fluid-rock interaction models for CO2 injection/storage. Furthermore, in this workshop geochemical and 1D reactive transport models using USGS's powerful and open-source geochemical simulator i.e. PHREEQC are demonstrated. This workshop 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. "

    Please do not hesitate to contact us at should you have any questions about this workshop.
