Orinoco Oil Belt Heavy Oil Interpretation

This work reviews some geological and geophysical characteristics of the crude oil and the reservoir rocks in the Orinoco Oil Belt. Expected seismic responses are also analyzed, as well as seismic data. Usual conditions and recommendations are given about the use of Direct Hydrocarbon Indicators (DHI) and the use of SMT KINGDOM attributes and Spectral Decomposition to facilitate the interpretation.

The singular characteristics of Orinoco Oil Belt heavy oil reservoirs and their strategic importance invite a study and preparation of the resources available for the interpretation of the seismic data. The goal is to improve the performance of future interpretation work using SMT KINGDOM software.
