Seismic attributes in reservoir characterization: an overview

The present study focuses on a literature review using seismic attributes in the characterization of hydrocarbon reservoirs. This work consists of examining the contribution of seismic attributes in the characterization of reservoirs. With this, it is necessary to identify and list the attributes involved in analyzing the reservoirs and their degree of involvement in the characterization of the hydrocarbon accumulation zones. The approach used is to classify attributes according to their levels of intervention as the attributes that circumscribe hydrocarbon accumulation zones such as instantaneous frequencies. Thus, the attributes which make it possible to analyze the seismic facies must be enumerated to determine the type of hydrocarbons. The aim of this work is not only to review the literature on the use of seismic attributes in the characterization of reservoirs but also to expose the limitations of these attributes in the study of reservoirs to search for the most adapted attributes that have never been used in reservoir analysis. As a result, several seismic attributes used in reservoir characterization will be evaluated while demonstrating their strengths and limitations to consider either the combination of certain attributes or the experimentation of new attributes in deepening the knowledge on the study of reservoirs. This work will contribute to a more sophisticated study in this domain.
