Brinell Hardness to Identify Unconfined Compressive Strength

Rapid, non-destructive, core-based strength logs using Brinell Hardness and Ultrasonic Velocity can rapidly identify the relative rock strength in conventional cores over large depth intervals. This measurement provides a "quick-look" at geomechanical properties.

• Provides the relative strength along the length of the core
• Identifies the weakest & strongest areas over large depth intervals
• Provides a nondestructive strength profile vs. depth
• Provides high resolution logs with multiple rock mechanical parameters
• Readily converted to UCS
• A helpful guide in determining which areas require additional core analysis
• Superior tool for strength diagnostics in rubbled shale

• Provides a nondestructive strength profile vs. depth
• Provides high resolution logs with multiple rock parameters (Vs, Ed, UCS)
• Probes full diameter of core rather than just the top surface
• Sonic velocities are an industry standard for indirect determination of strength
