  • CLASSIFYING THE REACTIVITY OF VOLCANIC ROCKS FROM THE SERRA GERAL GROUP: AN APPROACH USING A PROPOSED REACTIVITY INDEX (RI)
    Stephanie Carvalho da Silva, João Pedro Zielinski, Erico Albuquerque Santos, William Jeovanini Fucks, Antônio Rosales Gonçalves Oliveira, et al.
    Boletim Paranaense De Geosciencias, 2025
    The increasing global interest in CO₂ mineralization in basaltic rocks has led to studies within Large Igneous Provinces (LIPs), particularly focusing on their carbon storage potential. In South America, the Serra Geral Group (SGG), part of the Paraná-Etendeka Province, has been the subject of investigations due to its compositional diversity and extensive volcanic sequences. This study assesses the applicability of the Reactivity Index (RI) as a predictive tool for geochemical reactivity in six SGG volcanic rock samples, compared with two Icelandic basalts and one Columbia River Basalt (CRB). Results reveal RI values for SGG samples ranging from -11.1 to -6.7 log mol/s, aligning well with the observations from batch reactor experiments. Higher RI values were associated with increased reactivity, supporting the use of the index as a reliable proxy, especially in preliminary evaluations, although it does not account for textural characteristics or surface area variations. The samples from SGG, Icelandic, and CRB showed similar RI values. When integrated with petrography, surface area, and chemical data, the RI provides a promising tool for evaluating the reactivity of volcanic rocks in carbon storage strategies.
  • UNDERGROUND CO2 MINERALIZATION POTENTIAL IN PARANÁ STATE: PRELIMINARY ASSESSMENT OF BASALTIC ROCKS FROM SERRA GERAL GROUP
    Erico Albuquerque dos Santos, João Pedro Tauscheck Zielinski, Stéphanie Carvalho da Silva, Antônio Rosales Goncalves Oliveira, William Jeovanini Fucks, et al.
    Boletim Paranaense De Geosciencias, 2025
    The Paraná Basin's CO2 geological storage potential is significant due to its coal deposits, saline formations, CO2 emission sources, and pipeline network. Recent interest has shifted to volcanic rocks containing divalent cations, facilitating mineral carbonation. The basin's volcanic rocks have an estimated CO2 storage capacity of 2,840 Gt and areas of ca. 174,000 km2 in total were identified in different parts of Brazil. Paraná State, with its vast geological data, is ideal for a detailed assessment, especially in the Serra Geral Group (SGG), which covers over half of the state. Using different methodologies, the CO2 storage capacity in this area was estimated between 79 to 654 Gt, with further research required for precise quantification and the identification of possible reservoirs for CO2 injection.
  • IDENTIFICATION OF POTENTIAL CO2 INJECTION ZONES IN THE SERRA GERAL GROUP: A GEOPHYSICAL ANALYSIS OF LEGACY DRILLED WELLS

    Boletim Paranaense De Geosciencias, 2025
    Os basaltos do Grupo Serra Geral (GSG), na Bacia do Paraná, têm despertado interesse devido ao seu potencial para mineralização de CO2. Apesar de sua ampla extensão (~787.000 km²), dados geológicos são limitados, dificultando a identificação de zonas de armazenamento. Este estudo propõe um fluxo de trabalho integrado baseado na interpretação de perfis geofísicos de quatro poços (1-PT-1-PR, 2-AN-1-PR, 1-API-1-PR e 1-AV-1-PR) situados em uma área com potencial para armazenamento geológico de CO2. O poço 1-PT-1-PR foi usado como modelo de referência e revelou padrões distintos de interiores de fluxo e horizontes entre os fluxos. A porosidade foi estimada utilizando uma relação entre velocidade e porosidade baseada nas velocidades da onda P. Foram identificadas zonas de alta porosidade (Φ >10%), associadas a topos ou bases de derrames e derrames compostos. Intervalos de alta porosidade apresentaram valores de densidade reduzida (~2 g/cm³), porosidade até 30% e velocidades de onda P baixas (~3,1 km/s). Nos demais poços, também foram identificados múltiplos intervalos de alta porosidade, com “net-to-gross” variando entre 19% e 43%. Picos de raios gama, excursões positivas no perfil de caliper e valores reduzidos de resistividade sustentam a presença de zonas porosas e alteradas. Os resultados indicam a recorrência e possível continuidade lateral desses intervalos, reforçando sua viabilidade como reservatórios. O método aplicado contribui para delimitar zonas potenciais para futura injeção de CO2 no GSG. Trabalhos futuros serão direcionados à correlação sub-regional, com o objetivo de embasar projetos de mineralização voltados a áreas específicas.
  • Water-Alternating CO2 Injection in Carbonate Reservoirs: A Review of Fluid-Rock Interaction Studies
    Diogo Reato Marçon, Rodrigo Sebastian Iglesias, Aline Machado de Azevedo Novaes, Rafaella Magliano Balbi de Faria
    SPE Journal, 2024
    SummaryWater-alternating-CO2 (CO2-WAG) injection is a well-established method for enhanced oil recovery (EOR) and a promising option for geological carbon storage. The alternating injection of this gas with water also increases carbonate rock reactivity, which is higher than that in siliciclastic reservoirs, affecting the porosity and permeability near the well, thereby impacting the injectivity and well integrity. The composition of the produced water is also affected, increasing the potential for inorganic scaling. Moreover, reactivity also changes the pH of the produced water, thereby affecting material selection for producer wells. The characterization and modeling of such fluid-rock interaction effects are challenging but valuable for designing and optimizing the CO2-WAG process. To assess the current knowledge on this topic, we present a review encompassing laboratory- and field-scale studies of fluid-rock interactions resulting from CO2-WAG processes, particularly those pertaining to changes in the porosity, permeability, and produced water composition. Numerous studies within this scope have been published. This review summarizes the most pertinent findings and identifies opportunities for further research. In laboratory-scale studies, the main necessity is to expand the range of experimental conditions and parameters, either by conducting experiments with different mineralogies under representative reservoir conditions (e.g., pressure, temperature, and hydrodynamics) or by incorporating an oil phase, as such studies yield data essential for field-scale simulations, thereby enhancing their reliability. Addressing gaps in field-scale studies involves integrating the phenomenon of relative permeability hysteresis when assessing the impact of carbonate rock dissolution on the injectivity during CO2-WAG, as these phenomena are concurrent. Finally, we advocate for studies that establish an upscaling methodology for translating laboratory results into field-scale reactive transport simulations.

  • CO₂-shallow groundwater interaction and related hydrogeochemical mechanisms: A review on reduced-scale CO2 release field experiments
    João Pedro T. Zielinski, Clarissa L. Melo, Rodrigo S. Iglesias, Pedro R. Reginato
    Greenhouse Gases Science and Technology, 2023
    Carbon capture and storage (CCS) has been highlighted as a crucial technology for reducing carbon emissions, yet CO₂ leakage from the reservoir is still a matter of great public concern, especially because of water pollution reasons. Hence, reduced‐scale CO₂ release experiments have been conducted worldwide to study hydrogeochemical response in shallow groundwaters. Although other reviews have been previously published, this study reviews critical data to establish a geochemical process‐based framework of the scientific findings. Following this, four mechanisms were found to be responsible for hydrogeochemical behavior: (i) ion exchange is mainly responsible for short‐lived increase in Mg, Ca, Ba and Sr concentrations; (ii) sorption and desorption processes were related to heavy metal and trace element variations, seemingly due to the presence of oxyhydroxides and clay minerals; (iii) silicate and carbonate dissolution played different roles as a function of specific aquifer mineralogy, releasing metals or influencing divalent cations response; (iv) conservative, mixing and oxidation processes were pointed out as possible mechanisms regulating variations of Cl⁻, SO₄2⁻ and NO₃⁻. Although studies suggested no parameter exceeded potable limits, most experiments were short‐lived, possibly overlooking the CO₂ leakage response in a long‐term exposure. Hence, further work is still needed specially to support relevant environmental legislation. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.

  • CO2-water-rock interactions in undeformed and sheared claystone caprocks from Northern Europe
    Roland Vernooij, Tiago de Abreu Siqueira, Suzanne Hangx, Christopher Spiers, Marcelo Ketzer, et al.
    Greenhouse Gases Science and Technology, 2021
    One of the most promising, cost‐effective, and readily available technologies for reducing greenhouse gas emissions to the atmosphere is the capture and separation of CO2 from large stationary sources and storage in geological formations. Storage security, especially in the early stages of operation, is mostly guaranteed by caprock formations with very low permeability overlying the reservoir, capable of containing the injected fluid. Chemical alterations of the formation brine, caused by CO2 injection may cause dissolution and precipitation of secondary minerals, potentially increasing the risks of leakage from the reservoir. In order to evaluate these processes and their potential to induce the formation of leakage pathways in ultrafine fault gouges, a series of batch experiments was performed on crushed and sheared samples from three different caprock formations from Northern Europe (Sollingen, Röt and Opalinus claystones). The experiments were supported by numerical models of the kinetics of mineral dissolution and precipitation simulating the same experimental conditions, and over a longer time (10 000 years). Minor mineral alterations were observed after the batch experiments, the most important being: illite dissolution for the Opalinus and Röt formation samples, and dolomite dissolution and the transformation of illite and chlorite into kaolinite for the Sollingen sample. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd.

  • Modeling CO2 flow in support of a shallow subsurface controlled leakage field test
    Rodrigo S. Iglesias, Cristiane Romio, Clarissa L. Melo, Ana Paula S. Musse, Fátima do Rosário, et al.
    Greenhouse Gases Science and Technology, 2019
    Controlled release of carbon dioxide (CO2) into the soil and atmosphere is performed to test detection and monitoring tools, for which several field laboratories were established by a number of institutions worldwide. Numerical simulations of CO2 behavior in the shallow subsurface region are other forms of validation and verification of the leakage pathways and destinations. These studies aim to improve monitoring and verification of CO2 in case of unexpected leakages for public assurance. In this work, we present the results of a numerical modeling study conducted to simulate the injection of CO2 as carried out during a field test in Viamão, southern Brazil, where 20 kg day–1 of CO2 was pumped for 30 days through a vertical well 3 m below ground in an altered granitic soil. Multiphase flow simulations were performed with the TOUGH2/EOS7CA software for unsaturated porous media, using field data and injection parameters, including sensitivity tests to permeability direction, diffusivity, and boundary conditions. Results with increased horizontal permeabilities are in better agreement with the field observations. In this condition, mass balance calculations indicate approximately 90% of injected CO2 (20 kg day–1 during 30 days) remains in the soil after 180 days from injection start, consistent with the measured flow through the soil–atmosphere interface. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.
