Assessing the impact of thermal feedback and recycling in open-loop groundwater heat pump (GWHP) systems : a complementary design tool

Milnes, Ellen ; Perrochet, Pierre

In: Hydrogeology Journal, 2013, vol. 21, no. 2, p. 505-514

Thermal feedback and thermal recycling in open-loop groundwater heat pump (GWHP) systems occurs when a fraction of the injected water in a well doublet returns to the production well. They reflect two different mathematical representations of the same physical process. Thermal feedback assumes a constant injection temperature, while thermal recycling couples the injection and...

Understanding diagnostic plots for well-test interpretation = Comprendre l’utilisation des graphes de diagnostic pour l’interprétation des essais de pompage

Renard, Philippe ; Glenz, Damian ; Mejias, Miguel

In: Hydrogeology Journal, 2009, vol. 17, no. 3, p. 589-600

In well-test analysis, a diagnostic plot is a scatter plot of both drawdown and its logarithmic derivative versus time. It is usually plotted in log–log scale. The main advantages and limitations of the method are reviewed with the help of three hydrogeological field examples. Guidelines are provided for the selection of an appropriate conceptual model from a qualitative analysis of the...
