Core lifters
A spring steel ring that grips the core at the end of a run so it can be broken and brought to surface. Match the lifter to the bit size and the intended core barrel.
Discuss your requirements
SYSTEMS / FIELD EQUIPMENT
Drilling equipment
From the casing shoe to the core barrel, downhole components work together to cut, stabilize and retrieve core. Explore the drill string and ask us about size and compatibility.
DOWNHOLE / CORE BARREL COMPONENTS
Inside the drill string
Core recovery depends on how the cutting tool, barrel and retrieval components fit together. Select a part below to discuss its size, thread and place in the assembly.
Core lifter casings
The tapered housing that seats the core lifter behind the bit. Its fit affects how the lifter closes on the core during retrieval.
Discuss your requirementsImpregnated diamond casing shoes
A diamond-impregnated cutting edge fitted to the casing string for advancing casing through overburden and into competent ground.
Discuss your requirementsReaming shells
Positioned behind the bit to help maintain hole gauge and guide the drill string. Choose geometry and diamond protection for the formation.
Discuss your requirementsInner tubes
The tube that receives and protects the core inside a wireline core barrel. Tube length and assembly details depend on the drilling system.
Discuss your requirementsOuter tubes
The structural outer barrel that surrounds the inner tube and connects the downhole assembly to the drill string.
Discuss your requirementsOvershots & retrieval parts
Wireline retrieval components used to latch and bring the inner tube assembly to surface without pulling the full rod string.
Discuss your requirementsCouplings & adapters
Connections between drill string and core barrel components. Thread and size compatibility need to be checked across the full assembly.
Discuss your requirementsORE DYNAMICS / DRILLING EQUIPMENT
Check the complete downhole assembly.
Core lifters, casings, tubes and retrieval parts serve different steps in a wireline coring run. Their dimensions and threads have to match the bit and barrel system.
Send the hole size, core barrel series and existing connection details when enquiring. We can identify the parts that fit your drill string.
