Abstract
The disposal of spent geothermal fluids from power plants an nonelectric installations is a major expense to the resource developer. Subsurface injection, the most favored of all disposal options, accounts for 10-20% of the cost of power from a binary fluid cycle power plant. The disposal of liquid effluents has been successfully demonstrated a a number of geothermal sites but numerous technological difficulties must often be overcome, including hostile fluid chemistry, large disposal volumes, adverse environmental impacts, the site specific nature of geothermal resource, and the lack of geothermal reservoir definition
