Geothermal Energy is the thermal energy stored and generated inside earth’s crust. Geothermal well Drilling is a process of making a borehole into earth to tap the resources in reservoirs such as oil, gas, water, heat, steam and others.
How Geothermal drilling done?
Geothermal drilling can be of two types:
Near surface geothermal (up to 400m deep)
Deep geothermal ( exceeding 400 m)
The steam from underground reservoirs through a pipe system enters turbines and powers the generators ,which in turn provides electricity to the grid. The steam condensed and piped back into the earth through the injection well to continue the cycle.
Why drilling is performed?
Exploration- The initial employment of drilling in geothermal prospecting is aimed at providing proof of exploitable steam and data .
Production and re -injections- Additional wells are drilled.
Make -up- is done to replenish the reduced steam delivery.
Management of drilling process
Drilling can be broken into drilling operations which involves the actual drilling process and running of castings, cementing process, drilling fluids operations, eg., air drilling, well logging, drill pipe inspection service. Various contract are drawn to avail all these services depending on the well design and anticipated drilling problems. A representative of the company is appointed to represent the client on a 24 hrs basis. Other specialised requirements like fishing are obtained as and when need arise.
Types of geothermal Heat Pump systems
Closed-loop system- It circulates an antifreeze solution through a closed loop.
Horizontal loops-It is more cost effective and suitable for residential installations.
Vertical loops — It is suitable where soil is too shallow for trenching and they reduces the disturbance to existing landscaping.
Open loop system- It uses well or surface body water as the heat exchange fluid that circulates directly through the GHP system.
Geothermal energy method has the potential of becoming the leading technology for reducing greenhouse gas emissions. The deeper we drill the more energy can be acquired which will be economically viable.
Pros of geothermal Energy
The emission intensity of existing geothermal electric plants is on average122kg of CO2 per kilowatt-hour of electricity about one-eight of a conventional coal-fired plant.
Geothermal plants uses 404 sq meter per GWH VS 3632 for coal and 1335 for wind farms.
It is available 365 days unlike solar and wind energy .
which helps in saving 80% over fossil fuels when used directly.
