The project hopes to use the “water hammer” drilling method developed by a local company Hanjin D&B. The water hammer method is a drilling technique whereby the injection well transmits strong water pressure to the drill bit, moving it up and down like a hammer. The method is not only faster than the standard roller cone bit method, but it is cheaper as well.
GRC member David Blackwell, a professor of geophysics at Southern Methodist University in the USA and an expert on deep geothermal heat, was present at an international symposium on the topic that was held at the Kim Dae-jung Convention Center after the investment agreement was signed on Wednesday.
“Using Hanjin’s water hammer method, it will be possible to build deep geothermal power generators with a capacity of 50,000 MW by 2050,” Professor Blackwell said. “That is enough to replace fifty nuclear power plants around the world.”
