Geometric Seismic Attributes of Boca de Jaruco Oil Field

Abstract

This paper focuses in determining the Geometric Seismic Attributes in the central block of Mouth ofJaruco oil field to decrease the uncertainty in the structural design. The three dimensions seismic datacollected and depth migration processing results were used and was defined that the surface isassociated to the main reserve. A Geometric Attributes maps elaboration (Azimuth, Dip, Curvature andRoughness) work flow was developed; and was able to determine structural elements, where traditionalseismic data were not always able to demonstrate a confinable image of the geological structure. Thisstructure includes three structures between 1122 and 1200 m in depth. The Azimuth Attribute differentiatesthe southern flank from the northern flank; and defined accurately the top of the structure. The DipAttribute indicates values of layers inclination between 5 and 30º, the structure top with lowers valuesand the flanks with higher values, mainly to the south. Curvature and Roughness attributes reveal theareas of faults or channels.
