Operational Overview
The drilling fluid circulates through the annular space between inner and outer tubes, exiting via the diamond bit throat and returning between the outer tube and bore hole wall. Proper core lifter case adjustment and selection are critical for efficient core breakage and sample preservation.
The tapered core lifter design allows secure wedging onto the core during recovery operations, ensuring reliable core sample extraction.
