Dear All,
Can anyone briefly provide me on how to estimate the field intact strenth of material(MPa or KPa) from open hole drilling and gephysically logged (i.e. available data only: SD and GR_).I am currently reviewing the drill log data that only show the Gama Ray (GR) and Specific Density (SD) magnitude and its graphs for typical coal mine stratigraphy - consists of Claystone, Siltstone, Sandstone, and Coal. What I want to know is how to get the estiamte intact strength form Geophysical Log (SD & GR)? Is there any simple reference?
Many thanks.
