Análisis de atributos sísmicos para identificación de geoformas y ambientes de depositación: Caso de estudio Caribe Colombiano.

Abstract

The main objective of this research work was to investigate the most effective attributes and parameters in order to reach a better interpretation in the seismic data, identification of surfaces, geoforms and environments, starting with the bibliographic review of methodologies proposed by different investigators and by consulting the experts. It was based on data obtained from the Colombian Petroleum Institute (ICP) and using the free software Opendtect.

A comparision bewteen chopped data in the seismic and the barimetry was done, and it showed a better resolution in the seismic. Also, it looked radar images for the purpose of do a comparision in the palehorizon H1, but these radar images weren’t efficient for the goal of the investigation.

Seismic attributes’ bibliography collected was analized; in Opendtect software the attributes contained on it were reviewed and 25 attributes were tested in the seismic data obtained from the Colombian Petroleum Institute (ICP), the relevant attributes were selected for this investigation.

Previous identifications in the seismic data were done in order to compare them in data already processed with seismic attributes. An improvement in post-processed identification is noticed and the identification of structural and stratigraphic anomalies in the seismic data is also highlighted.
