SYNOPSIS
The Maui Field lies within the Taranaki Basin, New Zealand’s only known commercially producing hydrocarbon province. Its geological history, marked by complex turbidite deposition, provides a compelling framework for stratigraphic modeling and reservoir characterization.
This case study demonstrates how PaleoScan™ technology was applied to build simulation-ready reservoir models from seismic data in the Maui Field. A 3D Relative Geological Time (RGT) model allowed for precise delineation of stratigraphic surfaces and bedset terminations, enabling enhanced interpretation of channelized turbidite systems. Spectral decomposition and RGB-blend visualizations highlighted geobodies, while multi-frequency classification techniques aided their extraction. The RGT grid was populated with rock properties at seismic resolution using well log data, supporting detailed property modeling for simulation. The result is a high-resolution stratigraphic framework that captures heterogeneity and supports development planning.
