Experimental Environment

The DSC has a modular experimental environment that allows technical components and processes to be analysed on a real scale. The centrepiece is a high-performance, field-tested pump system to which various experimental set-ups can be connected.

The centrepiece of the equipment is the pump system, which can be flexibly adapted to different test set-ups.

The adaptive horizontal test rig functions as a drive unit for experimental tests on horizontal wells, but can also be used flexibly for component tests, e.g. on drilling motors.

The currently available rock chamber is used for investigations into drilling dynamics and their effects on rock destruction processes.

The Flow Loop enables the investigation of multiphase transport processes in the flushing system (cuttings discharge), taking into account the dynamics of the drill string using optical and ultrasound-based sensor technology.

The Pulse Propagation Test Stand is used to investigate the effects of pressure waves on the rock destruction process, such as those caused by the use of hammer drilling tools.

At the vertical test rig, rock destruction processes of prototype drilling tools are tested up to real scale.
