How does core drilling retrievals work? There are two main methods:

  • The conventional  method.
  • Wire line

The whole drilling string has to be taken out of the drill hole regardless of the drilling method used.

Core drill bits do ware out and are taken out and new drill strings with different or new drill bits are replaced to keep drilling as effective and productive as possible. Choosing the correct drill bits are essential for productivity and experienced core drillers will know exactly what drill bits will work best for the material to be drilled into. All the core samples, conditions and losses if any are logged.
