Visser and Smit Hanab has therefore proposed to perform the intersection at an alternative, rather unique way, namely with an'arc-drilling' (length 172 meters).
This arc drilling is a variant of the known controlled horizontal drilling technique, the 48'' pipe is bent mechanically prior to the withdrawal.
There are three sections in this drilling (3x54 meters) of pre-bent tube sections constructed, which can be drawn in the borehole one by one. As a result, the required length of the bore is significantly reduced.
