MODELING & DESIGN
For clients interested in CO2 storage within porous media, Geogreen can provide a variety of engineering services. The detail of the work can range from helping clients orient themselves to potential a storage project in terms of where to store the CO2 and how the injected emissions will behave over the life of the project with projections of how the CO2 plume will evolve after the project has stopped injection and has proceeded through closure, to helping incorporate CCUS as a carbon management option for a group of emission intensive industries in proximity.
Key drivers effecting the development of storage projects include: 1) demonstrating permanent confinement of the injected CO2 within the storage formation is the central question of CCS project development, 2) validating the theoretical capacity with a rigorous site characterization is crucial for determining the actual storage capacity of a potential site, 3) modeling the CO2 trapping mechanisms for a specific site is an essential component for predicting a storage site's performance and efficiency - the optimization of which makes the selection of the injection well location very important, and 4) in most cases, the main issue to be managed is the pressure in the formation, which can be managed with a variety of techniques.
Uncertainties: a particular challenge when approaching a storage project, especially within a non-hydrocarbon bearing formation where the lack of data is a key issue, is managing the uncertainties within the various models that are created for the project by employing the appropriate physical and numerical assumptions.
Injection strategy: to safely and effectively inject and store the amount of CO2 that will be required for most industrial projects, a well-defined injection strategy is an essential tool for project developers.
Geogreen is able to provide clients requiring CO2 storage with an initial screening to help select storage formation candidates. Then Geogreen can manage the development of a storage project design, including the engineering, in terms of building a geologic model and performing injection simulations to define the storage site and the injection strategy. As the project moves from the design phase into construction and operation, Geogreen continuously updates the storage model and injection simulations with new data, which are key deliverables for risk assessment and permitting purposes.
Powerful modelling tools: Geogreen's in-house software and other engineering tools help with the quantification of the trapping and confinement mechanisms present within the target formation and with designing an optimal injection strategy. These models, which will be regularly updated throughout the project, will also help clients in maintaining a top rate safety management plan over the entire life of the project.
