Conrad Combi 300 drilling rig for Geothermal Boreholes | Drilcorp

The Drilcorp management team decided in 2022 that to move ahead strategically, the company would target the closed loop drilling market. This is to service the rapidly growing government push for zero carbon emissions and the removal of gas boilers as a form of heating as soon as possible. This market demands high production with small diameter 200mtr boreholes often constructed daily.

Following extensive research on drilling rig manufacturers, it was decided that Dutch manufacturer Conrad produced a rig that would be ideal for this application and an order was placed for a Combi 300 model. The rig would also complement Drilcorp’s specialist water supply borehole work. The rig had a one-year lead in period from date of order which was placed June 2022.
