Analysis Of Seismic Processing Influence On Marlim Field 4D

We present and discuss some preliminary results of the seismic processing analysis, which have been<br>developed in Marlim field time-lapse studies. This field has been used as a pilot project for time-lapse analysis.<br>The second seismic survey was acquired to enhance the seismic resolution at reservoir horizons, instead of<br>aiming at a specific time-lapse study. Preliminary feasibility analysis indicates low possibility of water flow<br>monitoring, but we are still investigating and learning from the data. At the present time, only the presence of a<br>secondary gas cap has been investigated. In this paper, we investigate the influence of seismic processing on<br>monitoring maps.
