Comparative Analysis between Prestack and Poststack Seismic Attributes in the Heidrun Oil Field

Abstract

Seismic attributes are important tools in the study of seismic interpretation in both exploration and reservoir characterization. With them it is possible to determine facies, structures (folds, faults, fractures), investigate anomalies that can be generated by fluids (water, oil or gas). It is noticed that historically the extraction of seismic attributes is commonly performed in the stacked data, this is due to the computational limitations of both hardware and software. But nowadays, technological advances allow us to work with prestack data that is normally underutilized for seismic interpreters. The objective of this paper is to compare the response of the seismic attributes of the prestack data with the stacked data, for better characterization of the reservoir. This methodology was applied in reservoir the Bat and the Fangst Group that belongs to the Heidrun Oil Field.
