Drillings

Smoy - Market leader in Scandinavian core drillings

Smoy's main product is drilling services consisting of surface and underground core drillings, percussion drillings, installations of ground water monitoring wells and versatile technical in-hole surveys as well as of other services related to drilling. Smoy has about 30 drilling units and we drill about 100 km of core drilling holes per year. The drilling rigs range from light 50 metre units on rubber tracks to heavy-duty 2000 metre units controlled by microprocessors.

Core drillings on the surface and underground are performed by units powered by diesel or electricity. Conventional or wire line equipment.

  • Sample diametre range 22- 102 mm.
  • Double or triple core barrels with split inner tube.
  • Core recovery is improved by multi-component polymers.

Percussion drillings are usually performed to obtain soil or rock samples or for securing a rock surface. Samples are taken by: Flow-through samplers with 0-16 or 0.19 litre volume.

  • Tube samplers with 0.45 – 1.30 litre volume.
  • Wire line samplers with 0.87 – 2.60 litre volume.

Installation of ground water monitoring wells is a part of our drilling services.

Smoy offers a range of technical surveys and services related to drilling.

  • 3D directional survey of holes optically or magnetically
  • Directional drilling and branching of holes by wedging or eccentric core barrel
  • Sample orientation by various methods
  • Water pressure tests
  • Geophysical in-hole surveys
  • Video surveys or digital imaging of holes
  • Geological logging of core samples
  • Determination of elastic properties of core samples
  • Positioning with precision GPS
