A problem frequently encountered in oil exploration in some Brazilian sedimentary
basins is the presence of diabase sills intruded in the Paleozoic sequences. Diabase
sills reduce the seismic imaging quality. The modeling of these complex geological
situations allows the best understanding of them, and consequently the progress in
the development of methodologies and technologies that minimize its effect in the
diverse stages of the oil and gas industry. In the last years, diverse modeling and
visualization techniques have appeared and gained a new importance in the
resolution of problems found in oil exploration. The geological and geophysical
modeling software called Geological Object Computer Aided Design (GOCAD) is
one of these techniques. In this work was used this technique to build 3-D models of
a area of interest of PETROBRAS referent to the Amazonas basin (Brazil). This type
of modeling contributes in the resolution and understanding of the problems
produced by the presence of diabase sills in this region. It is also important to verify
the efficiency of diverse seismic methodologies to get a best illumination of these
complex geological structures in deep. |
