[MIS11-P13] An attempt to integrate 3D seismic and borehole datasets: construction of a 3D geomechanical model at the Nankai Trough, SW Japan.
Keywords:scientific drilling, data integration, nankai tough
As one of such initiatives, we used 3D seismic data and well data acquired at the Nankai Trough offshore Kii Peninsula, Japan, where extensive scientific drilling and geophysical surveys performed by the International Ocean Drilling Programme (IODP) and JAMSTEC, to construct a geomechanical model. The technique has been utilized for commercial purpose by the oil and gas industry to optimize production / well placement in the existing fields and to avoid borehole failure, but rarely used for scientific purposes. In this presentation, we are going to report some updates of the modelling, and discuss how such approach is useful for future scientific drilling.
