Seismic interpretation and data management by using opendtect and qgis: case study in the North Sea, Netherlands

Abstract

Seismic exploration method is one of the most important geophysical methods widely applied in the survey of deep geological structures. The seismic wave diagram is related to the acoustic impedance characteristics of the rock environment to help reflect the images of geological objects below. Effective management of the resulting data before and after seismic interpretation will help scientists have an overview in assessing geological objects to be studied. This management process is demonstrated by the need for information to be arranged in a unified manner and the need to quickly update and extract the resulting information. In this paper, our interest is in analyzing seismic data to highlight geological features including gas chimneys and geological fault systems in the North Sea region, the Netherlands. I will conduct two phases of analysis to serve the data management process. First, seismic properties such as entropy and homogeneity composition properties are applied to clarify the position of gas chimneys and geological faults in three-dimensional space. The second process is to extract the interpretation results of these two features into an open source geographic information system. As a result, each feature will be represented on a geographic map through their coordinate value along with images of the object's seismic properties.
