Geochemical Modelling of the Fracturing Fluid Transport in Shale Reservoirs
Energies, 2022 Field operations report that at least half of the fracturing fluid used in shale reservoirs is trapped. These trapped fluids can trigger various geochemical interactions. However, the impact of these interactions on well performance is still elusive.

The Canadian Journal of Chemical Engineering, EarlyView.We clarify how Gibbs‐energy‐minimization models for aqueous‐amine CO2 capture fail when conservation constraints and concentration conventions are inconsistent. Exact standard‐state conversions and Reaktoro case studies show that P(CO2)‐loading fits can mask non‐unique parameters and wrong speciation, motivating complete water‐inclusive formulations ...

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs
Deep Underground Science and Engineering, EarlyView.A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Trace element mobility during CO2 storage: application of reactive transport modelling [PDF]
E3S Web of Conferences, 2019 The geologic storage of CO2 carries both physical and chemical risks to the environment. In order to reduce those risks, it is necessary to provide predictive capabilities for impacts so that strategies can be developed to monitor, identify and mitigate ...

Combining paleoecology and modeling to explore cascading disturbances in forest ecosystems
Ecography, EarlyView.Climate‐induced cascading disturbance interactions pose a major challenge to the sustainable provision of forest ecosystem services to society. Developing a deeper understanding and enhanced capacity to simulate these interactions is essential for identifying disturbance‐induced tipping points in forest ecosystems, and for improving management in ...
