Abstract
One of the greatest difficulties found in reservoir<br>geophysics is the lack of new seismic acquisition and<br>pre-stack migration in 3D’s acquired in the past. A<br>way to improve the data image is to migrate the 3D<br>data in one step in the PROMAX processing package.<br>The response of it was excellent to get a good image<br>from faults, making its traces better focused in the<br>seismic sections, and so helping the mapping. This<br>fact is very important in the location of development<br>wells. The response was very satisfactory in<br>positioning pinch-outs features of channels and/or<br>lobes. It will be shown how this migration helped to<br>solve some troubles in a Campos Basin oil field,<br>where we have got a good amplitude response but<br>only 10 meters of reservoir, or we could not define<br>sand bodies limits.
