Quantitative Characterization of Methane Hydrate Reservoir in the Eastern Nankai Trough, Japan

Quantitative evaluation of methane hydrate (MH) bearing turbidite reservoir in the eastern Nankai Trough, offshore Japan is<br>conducted using a combination of 3-D seismic and well data. For constructing 3-D facies model, we have interpreted internal<br>sand body and stacking patterns of the channels to discuss reservoir heterogeneities of the turbidite channels. Geobody using<br>seismic volume rendering shows that the extracted body is distributed toward northeast to southwest directions in good<br>agreement with the direction of the channel-filling sediments according to the seismic sequence stratigraphic analysis.<br>Stacking patterns of channel facies are identified around the ß1 well.
