The study evaluates four state-of-the-art unsupervised clustering methods and employs Principal Component Analysis (PCA) for result refinement and differentiation. By analysing the effectiveness of the algorithms...

... and fracture damage zone analysis is done on three – dimensional seismic data from Sarawak basin in Malaysia. Commonly used seismic attributes to detect such features including variance, dip – magnitude, curvature, and gradient – magnitude are applied. Next, spectral analysis, as a tool to identify events...

... strike N20 to N40. This scale develops mostly in the denser reservoir units. Its spacing is controlled by the mean curvature of the seismic Top-Reservoir surface and by the structural depth. On the crest, it forms a connected network of a few tens of mD of equivalent permeability i.e. about 10 times...
