Abstract

Geothermal energy is a reliable, environmentally friendly resource efficiently transformed to other energy forms without any storage. Therefore, it has taken the attention of many investors in recent years. The investments in developing new technological materials, tools, fluids and methods to obtain fluid and heat transfer from a geothermal reservoir open the way to increase the efficiency of the entire geothermal power generation cycle in the medium and long terms. The effectiveness of a geothermal production system is directly related to the sustainability of the reservoir and production wells. At this point, the presence of CO2 is crucial for the life of a geothermal well as it provides extra pressure and a lifting mechanism to geothermal fluids along the wellbore.
