WHD-Drilling Method
BHG Brechtel invented a new registered drilling method for 480 mm horizontal drilling in water saturated aquifers. The developing process went on for nearly three years and was administrated by the inventor, Mr. Horst Derwand in close cooperation with the engineering company IB Dieterle. Notable companies of Mechanical Engineering and IT-Technology took part in this development because of their contribution of technical knowledge and mechanical skills.
