Abstract

The Siri Member is of great importance due to the heavy oil content that is present on the carbonate platform developed during the Tertiary. Considering this importance, we conducted a study with the objective of generating a high resolution stratigraphic framework, on 3rd order sequences, using the interpretation of two seismic sections and the analysis of fve well logs. The proposed framework allowed for the development of a depositional model that helped on the understanding of the evolution of the carbonate production of the Tertiary on the external platform of the Campos Basin.

The proposed model suggests the development of a mixed isolated platform (siliciclastic-carbonatic) generated over structural horst remaining from the rift fase, resulting from the beginning of the break up of South America and Africa. The detailed and regional interpretation of the seismic sections also allowed to infer a process of tectonic reactivation during the instal-lation of the carbonate platform. This process would have given the asymmetric character to the platform, and would have facilitated local process of simultaneous differential subsidence with the production of carbonate sediment.

 

Key words: Siri Member, carbonatics rocks, hight resolution stratigraphy, seismic stratigraphy, depositional model.
