Renewable energy is seen as the future source to meet the world’s growing demand, with geothermal resources offering a constant and independent supply.
Over the past century, the oil and gas sector has developed high level technologies for the exploitation of hydrocarbon reservoirs and most of this expertise is directly transferrable to geothermal exploitation.
This presentation begins with a review of the principles and uses of geothermal energy in today’s sustainable energy scenario, from district heating to electricity generation and/or combined heat and power (CHP) from Enhanced Geothermal Systems (EGS). The challenges faced by the geothermal sector within the broader energy landscape are also discussed.
Special attention will be paid to those aspects of geothermal exploitation that overlap with the oil and gas expertise, such as drilling and completions practices, the characterisation of fluid flow through porous media and in wellbores, and resources classification.
The comparison will show how hydrocarbon exploration and production complement geothermal exploitation (and vice-versa) and identifies technical areas where future research efforts could be addressed to enhance the technology transfer between these energy sectors.
