Hydrogen storage in heterogeneous reservoirs: evaluating well configurations an...
Pereira, Pedro; Carneiro, Júlio; Canhoto, Paulo; Pedro, Jorge; Khudhur, Karwan; Mazezo, AugustoThe urgency in mitigating the climate change effects and the expecting rise of energy consumption in the coming decades will require zero-carbon sources like renewables, fossil fuels with carbon capture and storage, and sustainable storage solutions like underground gas storage. Hydrogen geological storage in porous rock formations is expected to play a major role for sustainable energy systems, offering large-...
Interactions and Impacts on the Efficiency of Underground Hydrogen Storage in S...
Pereira, Pedro; Carneiro, Júlio; Canhoto, Paulo; Pedro, Jorge; Khudhur, Karwan; Mazezo, AugustoThis study, part of the H2GeoStore R&D project, investigates underground hydrogen storage in saline aquifers as a solution for large-scale, long-term energy storage to support renewable energy systems. Using reservoir simulations of cyclic hydrogen injection and withdrawal under various conditions and reservoir heterogeneities, the research evaluates performance metrics like injectivity, productivity, and stora...
3D static modelling with uncertainties of an offshore area in Portugal for CO2 ...
Pereira, Pedro; Khudhur, Karwan; Carneiro, Julio; Caeiro, Maria Helena; Santos, Mário; Lopes, Ana Mafalda; Revaux, CharlesThis study presents the construction of a 3D static geological model with uncertainty assessment for the Q4-TV1 prospect in the offshore northern Lusitanian Basin, Portugal, as part of the PilotSTRATEGY project. Using seismic interpretation, well data, and petrophysical logs, lithofacies and reservoir properties were simulated with geostatistical algorithms in Aspen SKUA. The models reproduced the geological fr...
Optimizing CO2 Injection Under Geological Uncertainties in CCUS: A Lusitanian B...
Khudhur, Karwan; Pereira, Pedro; Carneiro, Júlio; Goldman, Matthew; Blin, Gwendoline; Santos, Mário; Casacão, JoãoThis study, conducted within the PilotSTRATEGY project, explores the optimization of CO₂ injection under geological uncertainties in the Q4-TV1 prospect of the offshore Lusitanian Basin, Portugal. A static model integrating seismic and well data was coupled with dynamic simulations in the Big Loop framework, combining Bayesian optimization with uncertainty analysis. Geological risks, including intersecting faul...
Hydrogen geological storage in saline aquifers based on seasonal and hourly cyc...
Pereira, Pedro; Canhoto, Paulo; Khudhur, Karwan; Carneiro, Júlio; Pedro, Jorge; Mazezo, AugustoUnderground hydrogen storage (UHS) in saline aquifers is a scalable solution to balance renewable energy intermittency. This study evaluates the techno-operational feasibility of UHS through dynamic numerical simulations using a 3D heterogeneous synthetic model representing real reservoir properties of a saline aquifer. Two operational cyclic profiles (seasonal and hourly) were developed based on real energy da...
