Seismic attributes for fractures and structural anomalies: application in malaysian basin

Abstract

Seismic attributes are proved to be powerful tools for studying geological features on seismic data. In Malaysian Basin, intense efforts starting from this decade in seismic data acquisition and processing have resulted in significant improvement in data quality and hence the success of attribute application. Depending on the method used to calculate the attribute as well as the structure’s characteristics, one attribute can be more convenient than others for the desired objectives. Here, the focus is on detecting faults and anticlines in Central Luconia, Sarawak Basin. Therefore, different attributes useful for this purpose have been examined and compared to select the optimum selection of the attributes for further study of the data.   Based on the results, different attributes provide different information for the same geological event. So, it is better to combine the outputs obtained from attributes that can identify the anomaly at the required resolution level.
