Drilling deep holes with Wassara

Long straight holes

When drilling several long holes, minimised borehole deviation is crucial as the holes might collide otherwise. Wassara has proven its capability to drill long straight holes that are not affected by the water table. The ability to drill fewer holes to larger depths is also one of the advantages of the water-powered drilling technology – especially in restricted areas where space is limited.

Drills through different formations

Drilling in areas with layers of different formations can be tricky. Dense clay is one of the more troublesome formations for conventional equipment to handle, while Wassara penetrates it with maintained speed and straightness. The water-powered DTH hammer is capable of penetrating any formation.

Efficient and secure in water rich formations

To drill in water rich formations with air-powered equipment is hazardous; the air wants to push the water to the surface. This gives far reduced, if any, drilling efficiency. With Wassara, water in the formation is not a problem. The surrounding water will not affect the drilling at all. Nor does the drilling affect the water in the formation.
