At 3.4 kilometres, it's the deepest well ever drilled in Saskatchewan. The shaft has been sunk over the past two months as part of the Petroleum Technology Research Centre's Aquis-tore project to permanently store carbon dioxide deep underground. It will be the first project in the world to integrate commercial-scale CO2 capture, transportation and injection from a coal-fired electrical generating station into a deep geological formation. The gas will be turned into a liquid and piped from SaskPower's Boundary Dam Plant, then stored deep underground in a brine and sandstone formation to reduce greenhouse gases. The project is expected to be running by next year.
