ABSTRACT

Based on 3D sismic survey oil has been found in the sand stone reservoir of the Echo field malacca strait area. For eservoir management purose, the hydrocarbon discovery in this area should be follow by reservoir evaluation activities. Seismik attribute and log propoerties data has been used to identify the hydrocarbon potention in sand stone reservoir of the Echo field.

Seismik attribute prouced from the 3D seismik data exraction. Analysis hs been done to the time structure map,sesmik line attrbute and ountour map from the computtion of seismic attribute. Correlation between seismik attriute and log properties used to show the characteristic from oil reservoir

Seismic mapping shows the structural trap of anticline with the major NS trend. Attribute analysis shows the continuity of reflection characteristic in Echo field. From the correlation analysis between seismic attribute and log properties show that the hydrocarbon potention indicated by low dominant frequency range that is about 31,25 HZ – 68,34 HZ and low badwidth frequency range that is about 78,12 HZ – 85,94 HZ

Key word : seismik attribute, log properties, dominant frequency, bandwidth frequency
