Abstract

This study estimates the geomechanical properties of coal of varied ply lithotypes and mudstone by using the experimental Short Impact Load Cell (SILC) test. SILC is an alternative laboratory test for measuring tensile strength, stiffness, and specific fracture energy (fracture toughness). Available coal data is rare for low rank sub-bituminous coals that are the target for coal seam gas stimulation and extraction in the Surat Basin, Australia. Tested specimens include mini-core and irregular particles. The results demonstrate geomechanical properties can be derived and used in the reservoir numerical modelling investigation.
