Merus announce the second generation of the Merus down hole tools. The first batch of the new generation was now delivered to China. The DHT is fixed from outside on the tubing, and can be brought down the bore hole, to any depth required.  The DHT is available in standard sizes starting at 2 7/8", but can be customized to any size. The installation was done in April 2010 in Northern China. The down hole tool can be applied in either bore wells for water or as in this case in oil wells.
