The principal behind the development and manufacture of the Coreline™ tube is to have an exact, close tolerance, rigid, clear tube, sufficiently pliable for safe handling, to allow the rapid extrusion of sticky, broken or soft formation cores in their exact in situ state.

  • The Coreline system can be used on virtually any double tube corebarrel - conventional or wireline.
  • It immediately converts it to a triple tube corebarrel for a fraction of the cost normally incurred.
  • The Coreline system gives complete, in situ core samples. No disturbance or damage is possible in core extraction or transportation to your laboratories yet it allows the geotechnical engineer or geologist to immediately inspect the core on site.
