| Abstract | This paper addresses the well and near well formation damage mechanisms encountered on geothermal district heating wells producing/injecting low to medium temperature brines in an aqueous CO2/H2S environment. Corrosion of exposed metal surfaces and forming of heavy metal sulphide and calcium carbonate scale are reviewed. Remedial strategies based on material definition (removable fiberglass lining of metal casings) and downhole chemical inhibition technologies are presented and monitoring/economical aspects are presented in fine. |
