Ensemble Kalman Inversion for Geothermal Reservoir Modelling

Autor: de Beer, Alex, Bjarkason, Elvar K, Gravatt, Michael, Nicholson, Ruanui, O'Sullivan, John P, O'Sullivan, Michael J, Maclaren, Oliver J

Numerical models of geothermal reservoirs typically depend on hundreds or thousands of unknown parameters, which must be estimated using sparse, noisy data. However, these models capture complex physical processes, which frequently results in long ru

Data Space Inversion for Efficient Predictions and Uncertainty Quantification for Geothermal Models

Autor: de Beer, Alex, Power, Andrew, Wong, Daniel, Dekkers, Ken, Gravatt, Michael, Bjarkason, Elvar K., O'Sullivan, John P., O'Sullivan, Michael J., Maclaren, Oliver J., Nicholson, Ruanui

The ability to make accurate predictions with quantified uncertainty provides a crucial foundation for the successful management of a geothermal reservoir. Conventional approaches for making predictions using geothermal reservoir models involve estim

The reentrant condensation of polyelectrolytes induced by diluted multivalent salts: A mean-field level revisiting

Autor: Yong, Huaisong, Zhuang, Bilin, de Beer, Sissi

We study the reentrant condensation of polyelectrolytes in dilute solutions of small multivalent salts, whose phase-transition mechanism remains poorly understood. Motivated by recent full atomic simulation results reported by the Caltech group on ph
