Multilateral Closed-Loop Geothermal Systems as a Zero Emission Load-Following Resource

The Eavor-Loop™, a multilateral closed loop geothermal system (MCLGS), is introduced as a zero-emission load-following resource (ZELFR) that is globally scalable and can provide baseload or dispatchable electricity…

Eavor-Lite Performance Update and Extrapolation to Commercial Projects

Eavor-Lite™ is a full-scale demonstration project of a multilateral closed-loop geothermal system. An update is presented based on ~16 months of operations and testing. The project is located near Sylvan Lake, Alberta, Canada and consists of two 1.7 km long multilateral horizontal wellbores connecting two 2.4 km deep vertical wellbores to create a U-tube shaped closed-loop geothermal system.

Subsurface Characterization Methods for Multilateral Closed Loop Geothermal Systems

The production of heat and electricity from geothermal energy is an old concept and has been around since the early 1900’s. However, many geothermal projects are plagued by high up-front exploration costs, financing difficulties and geological risk of low permeability reservoirs which limits development past the exploration phase.

Case Study of a Multilateral Closed-Loop Geothermal System

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.
