With the recent introduction of more sophisticated drilling techniques, there is considerable variation both in nomenclature and the diameter of the core that can be extracted. With respect to wire line, the sizes are quoted as AQ, BQ, NQ, HQ and PQ which yield cores diameter of 26.97, 36.37, 47.62, 63.5, and 87.96 mm (1.062, 1.432, 1.875, 2.5, and 3.345 in.) respectively. The choice of core size is dependant on the type of ground that is being drilled and the cost. The most popular size is NQ series because as a general rule, the larger the core the better the recovery.
