Coring
Oil and Gas
Coring describes the process of taking rock samples from a well by means of a special tool called a core barrel. The core barrel itself may be thought of as a special storage chamber for holding the rock core. The core catcher serves to grip the bottom of the core and, as tension is applied to the drillstring, the rock under the core breaks away from the undrilled formation below it.
