Modelling cloggings in a geothermal reservoir

Due to an increase of precipitation reactions in water by temperature changes, cloggings canoccur in a geothermal doublet. A consequence of the cloggings is that the process of generatinggeothermal energy becomes inefficient eventually. Our goal is to determine which minerals playan important role in the clogging process in each part of the...

Algebraic Dynamic Multilevel Simulation of Coupled Flow and Heat Transfer in Heterogeneous Geothermal Reservoirs with Fluid-Rock Non-Thermal Equilibrium Effects

Accurate simulation of fluid flow and heat transfer in geothermal reservoirs is a crucial necessity for optimising energy extraction strategies. However, natural formations (including geothermal ones) extend large length scales (in the order of km), while their properties (e.g., heat and flow conductivity) can change in small (fine) scales (e.g....

Multiscale Finite Volume Method for Coupled Single-Phase Flow and Heat Equations in Fractured Porous Media: Application to Geothermal Systems

Modern geoscience challenges motivate the development of advanced simulation methods for large-scale geothermal fields, where single- or multi-phase flow is coupled with heat transfer equation in heterogeneous fractured formations. The state-of-the-art multiscale formulation for fractured media (F-AMS; Tene et al., JCP, 2016) develops an...
