In RC (reverse circulation) drilling, the fuel consumption is very high because of the air compressor. By using Wassara, you can save up to 80% of the fuel cost. This is in the first part of the borehole, where you don’t need samples. As this often is the major part of the distance to be drilled, you can save a lot of money in the total project. A rig that can do RC with air hammer is very well suited also for Wassara drilling. You won’t need weight rods etc. to protect the rig.
The RC drilling technology (with air hammer) in combination with core drilling is quite common in Australia, where multipurpose rig are used often. Instead of RC, you can use Wassara to reach the core sampling zone faster, without the heavy and expansive air compressor.
