The Electric Impulse Drilling (EID) uses high voltage impulses to destroy the rock. Without any mechanical interaction between a bit and the rock, it works with almost no wear. Because of that, there is a big potential for reducing roundtrips and non-productive time. In a current R&D project, an EID system is built up and will be tested in a shallow well. A very difficult task during the development is the adjustment of the process to high-pressure conditions.
