3D seismic interpretation

The dataset used in this study is the Maui 3D seismic volume from Taranaki basin, offshore New Zealand. A stack of 400 continuous stratigraphic horizons is produced from the Maui RGT model, even for complex areas where classical methods failed to achieve or would take a long time to complete. Integrated with seismic attribute mappings such as RMS amplitude and/or spectral decomposition, the horizon stack enables to navigate the seismic volume in stratigraphic order.

Bài viết giới thiệu phương pháp minh giải địa chấn toàn phần (global seismic interpretation method) được phát triển bởi Pauget và nnk. [1]. Mô hình 3D thời gian địa chất tương đối (3D relative geologic time, RGT) được xây dựng trực tiếp từ tài liệu địa chấn là kết quả của phương pháp này. Trong mô hình RGT, tuổi địa chất có sự tiếp diễn liên tục, được nội suy và xác định trên mọi điểm của tài liệu địa chấn 3D.

The geology of the Çankırı Basin has been studied using multi-source data including satellite images, aerial photos, gravimetric data and seismic sections, which are subsequently used to generate maps and a 3D model of that part of the basin covered by the seismic sections.

In this paper, we present the rapid method for determining the depth distribution of a sedimentary basin by combining the FFT-based and space domain techniques in gravity data interpretation. The method is tested on two 3D synthetic models which density contrast is constant and exponential variation with depth. Then, the method is applied to determine the depth distribution of Nam Con Son sedimentary basin in Vietnam. The obtained results coincide well with theoretical models and seismic data. The computation speed of the method is much faster than that of space domain technique.
