Audited Supplier General purpose conventional core barrels designed for coring in soft to hard homogenous and slightly broken formations with water, mud, polymer or air flushing. Although designed as double tube core barrels, all can be converted to triple tube by incorporating PVC coreliners. Available in 6 different diameters for metric (millimetre) hole sizes between 101 - 146 mm.
Due to its large fluid passage, it is more suitable than T2 type especially for obtaining core in soft and friable formations where it is necessary for high core recovery to use drilling water and mud.
