A comprehensive review of energy extraction from low-temperature geothermal resources in hydrocarbon fields

Hydrocarbon fields around the world may possess suitable features for low-temperature geothermal energy extraction (below 190 degrees C). Few demonstration plants prove the technical feasibility of power generation from such fields. Case studies are reviewed and discussed to identify deciding parameters for an economical geothermal system. An insightful discussion outlining the unique characteristics of a power project in oil and gas fields is presented. A low-temperature geothermal system set up on unused wells in depleted reservoirs must justify the challenging economics to become an investment opportunity. Interlinked economic, technical and geological parameters influence a profitable development. The long-term behaviour of the resource is uncertain and sustainable resource management in such fields is rarely discussed. Reservoir and wellbore simulations are likely to allow an improved understanding of resource behaviour. It will facilitate the evaluation of the reservoir capability to sustain the estimated capacity for longer.     «
