Wireline Drilling System Components
- Core barrel assembly
- Overshot assembly
- Drill rods
- Holding dog and hoisting plug
- Circle wrench and accessories
Operational Benefits
Wireline drilling technology enables core removal through the drill string using an overshot mechanism, eliminating the time-consuming process of removing individual rods. This system provides:
- High penetration rates with extended bit life
- Reduced labor intensity and operational costs
- Enhanced efficiency that increases with drilling depth
Double Tube Core Barrel Technology
Our double tube core barrels feature an inner and outer tube design that directs flushing water between tubes to protect cores from washouts. Available in both double motion and single movement configurations for various geological conditions.
Single movement double core tubes utilize bearing isolation, allowing only the outer tube and bit to rotate while the inner tube remains stationary, preventing core damage in severely fractured formations.
