Each well drilled with Epiroc rigs uses around 150 litres of water per minute. Today, water is a necessity for drilling to take place. In many places where Epiroc’s drilling rigs are used, there is a shortage of water, which makes the process more expensive but also less sustainable. But whether water is available on site or needs to be transported, the total amount of water used would need to be reduced. That’s why the company is looking for a solution that allows for the treatment and reuse of the water on site. The challenge here is to find a solution that can capture and purify the used water, as it contains large amounts of the drilled material, known as ‘borrkax’. Another challenge is that the solution needs to be compact and able to be applied to the existing rigs in use.
