ABSTRACT
This paper presents regional-scale stratigraphic and geo-property modeling using a random field approach. The Taipei Basin is selected as the study site. We initially collected and screened over 6,000 borehole data from the Geological Survey and Mining Management Agency of Taiwan database, then adopted the borehole fusion method to reduce them to less than 1,000. Following this, the stratigraphic-based geo-property random field developed in this study is used to simulate a series of paired 3D models of stratigraphy and geo-properties for the Taipei Basin, utilizing data from the fused boreholes. Finally, the study analyzes the uncertainties present in the stratigraphic and geo-properties models.
Keywords: Stratigraphic modeling, Geo-property modeling, Random field.
