ALS is able to provide direct and continuous measurement of mechanical rock properties using the Epslog scratch device, both at the wellsite or in the laboratory. The Wombat measures high-resolution continuous profiles of rock strength (UCS) and ultrasonic P-wave velocity synchronized in depth. A high-resolution picture of the groove is also taken after the tests.
• Profiling the rock mechanical properties (strength and elastic) of whole or slabbed core
• Portable and robust equipment
• Cost effective against conventional methods
• Rapid data acquisition (10m scratched and analysed per day per device)
• A clean fresh surface left by the scratch test may be suitable to conduct other measurements such as probe permeameter prior slabbing.
• Evaluation of wellbore stability;
• Sand prediction;
• Upscaling of reservoir properties for robust 1D MEM model leading to hydraulic fracturing design
• Identification of geomechanical facies
• “Scratched” material can be collected along the sample and analysed for mineralogical content (X-Ray Diffraction or FTIR)
• Improved plug selection strategy
