These tools can be deployed by wireline and conveniently changed to accommodate changing lithologies. The tool set contains the following:

• Shelby (Push) Tube
• Hydraulic Piston Core (HPC)
• Extended Shoe, Non-rotating
• Extended Core Bit, Rotating (The Alien)
• Diamond Core Bit (mining)
• Non-Sampling Assembly
