oa Significance of Amplitude Variations in Shaley Mass-transport Deposits - A Petrophysical-geophysical Correlation

For this work were used three high-quality 3D seismic volumes from SE Japan and SE Brazil, together with borehole data from the Nankai Trough. We show that, on 3D seismic data, seismic texture is defined as a reflection amplitude pattern that is characterised by the magnitude and variation of neighbouring data in a seismic volume (Chopra and Marfurt, 2007). We show the importance of seismic amplitude variations to assess the seal competence and reservoir potential of MTDs.
