    Frequently asked questions

    Our tools follow international Q-series standards (NQ,HQ,PQ,BQ) with thread profiles that connect directly to major core drilling rigs - including Boart Longyear, Epiroc (Diamec / Boyles series),and other standard-compliant machines. No adapter or modification needed to integrate into your existing drill string.

    Our standard double-tube system achieves 95%+ recovery in competent rock. For fractured or loose formations, our triple-tube system adds a split inner liner that shields the sample from the moment it enters the barrel - delivering complete, undisturbed core every run.

    Our core barrels are machined to tight concentricity tolerances, keeping the inner tube centered throughout each run. Combined with our reaming shells, the bore diameter stays consistent from top to bottom - so deviation stays within acceptable limits and your core reflects the true formation.
