Stimulation of geothermal wells is applying permeability stimulation/enhancement techniques toward solving the problem of limited well productivity.
Stimulation’s primary objective is to remedy and/or improve the connection of the wellbore with the natural fractures or faults in the geothermal reservoir, to improve permeability and therefore well productivity.
In the geothermal industry the predominant well stimulation techniques in use or under consideration are as follows:
- Acid injection, also known as ‘acidising’
- Hydraulic fracturing
- Deflagrationeflagration
- Thermal fracturing
