1Figures Cluster World Oct. 2004 OpendTect article For optimal printing quality do not copy Figures 3, 4 and 6a, 6b and 6c from this Powerpoint file. Instead use original tif images!The OpendTect logo is delivered in EPS format.Contact for other formats and/or questions.

Multiple attributes and interpreter’s knowledge are combined by a neural network to give the optimal view of the object of interest. In this case a salt dome.
