Probabilistic assessment of engineering rock properties in Singapore for cavern feasibility
… of the empirical methods, the RQD and Q-system, rock support can be estimated for different ground classes for an assumed cavern size. The cost per cubic meter of cavern construction, which includes excavation support using bolts and shotcrete, and grouting, is then estimated. To account for the …

DESCRIPTION OF THE BAKKEN FORMATION’S ROCK PROPERTIES OF THE WILLISTON BASIN, NORTH DAKOTA
It is possible to determine rock properties by utilizing seismic inversion techniques. The inversion technique is the most frequently used, by which the seismic interpreters derive lithology and physical properties. In this study, the 2D pre-stack seismic data was obtained from the analysis of Ross …
