General purpose conventional core barrels designed for coring in soft to hard homogenous and slightly broken formations with water, mud, polymer or air flushing. 聽 Although designed as double tube core barrels, all can be converted to triple tube by incorporating PVC coreliners.

Size: T6-76, T6-86, T6-101, T6-116, T6-131, T6-146.

—WM Series Double Tube Core Barrel
WM series double tube core barrels was developed as a solution to the ever present problem of recovering a high percentage of core when drilling badly fractured or broken strata or soft and friable material that is easily eroded by the circulating fluid. Mud or water can be used with this core barrel while drilling. It has more sturdy design compared to the metric series core barrels.

These聽triple tube core barrels are generally used for geotechnical purpose, designed to maximize core recovery in soft formations. Available diameter sizes from 35-146mm.
Wireline Triple Tube聽Core聽Barrels
Wireline triple tube core barrels are generally required in broken, fractured聽formations.They incorporate a third, split inner tube on base of wireline double tube core barrel. This can be pumped out of the inner tube after retrieval, allowing the core to be examined in its in-situ state.
B Series Single聽Core聽Barrels
B聽Series are single tube core barrels, often used in situations when the core preservation is not essential and for concrete coring. Available diameters 36-146mm.
