50 Tonne drilling equipment
Unique set-up for drilling experiments under in-situ pressure conditions
Pressure bombe

Pumps for mud circulation system
Drill bit
Equipment
The unit can test the performance of different drill bits or other drilling technology (e.g. jettting) on different rock specimen under different pressure conditions. Sensor techniques and shaker optimization techniques can be applied and tested, and the setup can be modified to test other flow techniques. Projects are planned to evaluate the performance of steering technology for horizontal/multilateral wells, a technique that will probably become invaluable to enhance the performance of geothermal wells.
Application areas
This unique facility allows testing of various drilling systems at dowhole conditions. Rock specimen can be placed in the pressure vessel to simulate various rock formations. The 50T compression stroke drilling machine is serviced by a full capacity mud circulation system with pumps and ring line and is connected to a shaker.
