... neural network (ENN), is constructed. The model is corresponding to reservoir physical property by the use of logging, core and test data, and it is employed to classify rock types of coal reservoir. The case results indicate that this model is feasible and effective in the rock classification, so...

... of sedimentary rock types that now constitute the Jurong Formation. Due to the humid tropical climate of Singapore, the Jurong Formation has been subjected to intensive chemical weathering and therefore, the rock strength in this region has been largely dependent on the extent of weathering that is subjected...

... by using 59 series of accurate triaxial test datasets which are belong to 20 different rock types selected from the literature. It has been shown that the proposed criterion is capable of predicting the triaxial behavior of rocks in both tensile and compressive regions. There are two coefficients...

... results obtained from six rock types fall into the moderate-to-low strength anisotropy classes. The comparison between the observed and predicted UCS values indicated that the prediction performances of the equations developed are quite well. Evaluation of strength anisotropy and empirical models...
