In areas of the subsurface the presence of complex geological structures
(e.g. faults, recumbent folds, dikes, diabase sills, salt domes, etc) reduces the
seismic imaging quality due to false structures. This difficult the success of
finding oil and recovering greater amount from existing wells. New technologies
(e.g. modeling and visualization) are being more and more used as a tool to
increase the ability to find new hydrocarbon reserves and improves the
efficiency of oil and gas exploration. With the seismic surveys and geophysical
studies complete, geologists build a digital 3-D geomodel of the subsurface to
help decide whether to develop an oil or gas field. Geomodeling is a vital riskminimizing
tool. In the oil and gas industry 3-D earth models are crucial
decision making and other purposes: to check the consistency between
geological objects, to plan the path of non-vertical wells, to monitor the
reservoir (4-D seismic), for the reservoir model construction, seismic inversion
and velocity analysis. In this work was used the 3-D modeling as tool to
modeling complex geological structures. The models correspond to complex
and synthetic 3-D models. The types of models were: structural, stratigraphic
and velocity. Additionally images had been generated to visualize the structure
internal of the studied geological structures. That is very important for the study
of the petrophysical properties and the fluid flow in the interior of one
determined reservoir.
