Multiattribute analysis of channel architectural elements within the deepwater Taranaki Basin, 3D Romney data

Abstract

The Taranaki Basin is located offshore, west of North Island, New Zealand. Within the study area, deepwater channel systems are present as a result of plate boundary movement and clastic deposition during the Plio-Pleistocene. Multiattribute analysis revealed a few interesting features that were identified and interpreted. After refining the horizon of focus, some interpretations were concluded as noise, while others were confirmed as geological deposits: (FLT 1) A high energy and high sweetness response along the northwestern portion of the main channel body was interpreted as a sand-rich levee deposit and (FLT 2) scalloping and elongate finger-like geometries were interpreted as noise.
