Why Geothermal?
8/4/2019 Present Situation and Future Development of Indonesian Geothremal
http://slidepdf.com/reader/full/present-situation-and-future-development-of-indonesian-geothremal 8/29
Advantages of Geothermal Using
Sustainable (Independence of climatic variation andweather change, independence of cost increase andfluctuation, deliverability and waste management of fossil
fuels) Renewable (Abundant source, will be available for the
foreseeable future)
High base load capacity, over 90%
Environmentally Friendly (Help to reduce GHG and CO2)
Reliable (Does not require extensive land)
Low operating cost compare to other RE NEXT

How an Enhanced GeothermalSystem Works
There are four main types of geothermal power plants: 1. Drill Injection Well
An Injection well is drilled into hot bedrock that has limited permeablility and fluid content, This isconsiderably deeper than water tables, at depths greater than 5,000 feet.
2. Inject Water Water is injected at sufficient pressure to ensure fracturing, or open existing fractures within thedevolping reservoir and hot bedrock.
3. Hydro-fracture Pumping of water is continued to extend fractures and reopen old fractures some distance from theinjection wellbore.
4. Drill Production Well A production well is drilled, intersecting the stimulated fracture system. The water is circulated to
produce steam. The water, depleted of its heat, is re-injected to be heated again in the fractures.
5. Drill Additional Production WellsMore production wells are drilled to extract heat form large volumes of hot bedrock to meet powergeneration requirements.
