Down hole directional drilling tools are used in oil & gas industry to drill for oil. They are used to control the direction of the drilling head in order to change direction from vertical to horizontal and to bypass obstacles in the ground. These drilling tools as well as the special tools „LWD - Logging While Drilling“, „MWD - Measurement While Drilling“, „Wireline Tools“, „Completion Tools“ and „Well Tractors“ are used in the underground.

The position and direction of the drilling tools are directed and controlled from the drilling platform. The drilling tools are driven up to 3 km depth and additionally, up to 9 km horizontally. They must be very small and are exposed to extreme operating conditions. The ambient temperature can reach up to 175°C, the ambient pressure up to 2000 bar and all the while being subjected to extreme vibrations and shock stress.

AKP  Micro-Pumps from BIERI, which are components of the directional control unit, ensure that the drilling tool reaches the target destination exactly and reliably. The  drilling direction is defined by three flaps in the tool, which are actuated by a plunger cylinder. Driven by a DC servo motor, our pumps ensure that reliable and accurate pressure is applied to the plunger cylinders.
