Drilling and Insitu Tests

Boring and Core Drilling (Off-Shore & On Land)


Offshore and Onshore drillings can be performed for geotechnical purposes. Onshore drilling operation can be performed by using rotary and percussion drilling system.

Rotary drilling can be carried out by using conventional or wireline system core barrels. By using wireline system; in different size double-tube or triple tube core barrels (NQ, HQ, PQ etc) can be selected. In conventional drilling, different series (T, R, etc.) with different diameter single-tube, double tube and triple-tube can be used.

During percussion drilling, boreholes could be drilled in different diameter by using different hammer (3", 4", etc.) and bit (85 mm,105 mm, 127 mm, etc.). Also, 164 mm diameter drills with ODEX method can be executed and casing can be placed parallel to the progress of drilling.

Suitable drilling method and core barrel type are defined according to the scope and purpose of the drilling work.
