The effect of dissolved methane on subsurface flow for heat production from geothermal aquifers

We investigate non-isothermal compositional flow in methane-rich geothermal aquifers by coupling a thermodynamic model and a dynamic flow model. For the thermodynamic model, we develop a MATLAB program, which calculates the thermodynamic equilibrium of the H2OCH4-NaCl mixtures at high pressure conditions and reservoir temperatures. In the same...

Doublet Spacing in the “Delft Aardwarmte Project”

In the “Delft Aardwarmte Project” cooled geothermal water is planned to be injected back into the producing formation. This paper describes the mechanisms occurring during injection and he prediction of the thermal breakthrough that are studied using a reservoir simulation model developed for the “Delft Aardwarmte Project” field properties....
