Results from a full-scale demonstration project of a multilateral closed-loop geothermal system are presented. The project is located near Sylvan Lake, Alberta, Canada and consists of two 2.5 km long multilateral horizontal wellbores connecting two 2.4 km deep vertical wellbores to create a U-tube shaped closed-loop geothermal system.
