Wireline Core barrels use inner and outer core for taking minerals or rocks samples, even while drilling is ongoing, in case the material of the rocks is too hard to penetrate by the core barrel, diamond core bits are used to increase its potential. Now it is ready to cut away the sample by inserting the diamond core bit, the samples is cut into the well and rotating the outer barrel around the inner barrel. This technique can also be used to prevent external water to the core sample when extraction.

Core barrel is a complex tool, technically, it is an assembly drilling tool, which is one part of the machinery. It is always used for drilling the hole that are extra hard, like mineral formation. ROSCHEN company offers three types, including the triple tube core barrels, double tube and singe tube core barrels, The sizes are among 1.5 to 3 meters. The core barrel always is used to take the mineral and rock samples.
