SplitLok™ System
Locked Down.
Open Up.
SplitLok™ is a one-piece core liner that secures the sample with maximum containment through every meter of the trip out of hole, then splits along a controlled surface profile for immediate, undisturbed core access. Downhole security and surface accessibility in a single system.
One System, Two States
Security When It Counts.
Access When You Need It.
Downhole
Firmly Locked
While drilling, the SplitLok™ liner remains firmly locked, ensuring maximum core protection and containment throughout the coring run and every meter of the trip out of hole. The one-piece liner construction eliminates the joints and failure points that multi-piece systems introduce.
Formation pressure, drilling fluid invasion, and mechanical disturbance are all active threats to sample integrity during the trip. SplitLok™ keeps the liner locked against all of them.
Construction
One-Piece Liner, No Joints
Target Formations
Soft and Unconsolidated to Fragile
Protection Mode
Maximum Containment, Full Trip Duration
Surface
Controlled Split
Once retrieved, the liner splits along a controlled profile, giving fast and safe access to the core for handling and evaluation. The split mechanism is engineered for precision — no improvised cutting, no risk of damaging the sample during exposure.
The core that entered the liner downhole is the core that reaches the analysis table. Intact, oriented, and ready for plugging, photography, and gamma-ray scanning without additional handling risk.

Performance Advantages
Six Advantages of One-Piece
Liner Technology
Core Protection
Enhanced Core Protection in Soft and Fragile Formations
One-piece liner construction maintains core integrity from the moment of entry through the full trip to surface, without the failure points of multi-piece designs.
Liner Reliability
One-Piece Design Eliminates Core Disturbance and Liner Failure Risk
No joints, no seams, no weak points. A single continuous liner reduces the risk of core disturbance and premature liner failure that can compromise the entire run.
Surface Handling
Efficient Split Mechanism for Rapid Core Exposure
The controlled split profile allows fast, safe access to the core at surface — reducing the time between retrieval and the start of wellsite analysis, sampling, and photography.
Decision Timing
Improved Decision-Making Through Timely Wellsite Analysis
Faster core exposure means geological and petrophysical assessment starts sooner, enabling more informed real-time decisions on next steps during the well program.
Rig Time
Reduced Rig Time Through Streamlined Operations
Reliable first-run capture and fast surface handling minimize the additional coring runs and rig floor delays that drive total well cost overruns in unconsolidated formation programs.
Recovery Quality
High-Quality Core Recovery for Longer, More Reliable Acquisition
SplitLok™ supports extended core intervals in formations where standard liners fail to maintain sample continuity, producing longer, higher-quality core columns for analysis.
Why Choose SplitLok™
Downhole Security.
Surface Accessibility.
Downhole Security
While drilling, SplitLok™ remains firmly locked, ensuring safe core retention through high-pressure, high-temperature downhole conditions and every meter of the trip out. The one-piece construction eliminates the liner failure modes that end coring programs prematurely.
Surface Accessibility
Once retrieved, the controlled split allows effortless liner opening and immediate core access — reducing handling risks, saving valuable rig time, and enabling faster wellsite decisions. The sample the liner brought up is the sample the geologist examines.
