| Abstract |
This paper focuses on the technology and problem areas related to the management of low enthalpy geothermal reservoirs dedicated to direct uses, chiefly space and district heating. Accordingly it reviews the headings, deemed the most sensitive, itemised below: - well drilling and completion - well restoration and workover - production and injection technology - corrosion and scaling thermochemical shortcomings - risk assessment - sustainable reservoir development. The latter, indeed a key issue, is illustrated by the reservoir simulation of two 50 year projected development scenarios in view of investigating well longevities and reservoir life. |
