ABSTRACT

We developed a generalization of the SEPlib software package capable to handle data with irregular spatial sampling, such as 3-D prestack seismic data. The new SEPlib, dubbed SEPlib90, is layered on the top of the old SEPlib, and shares with it the flexibility of use and the efficiency in accessing large amount of data. These attractive characteristics derive from two principles at the basis of SEPlib90 design: separation of the geometry information from the data traces, and exploitation of existing regularity, if any, in the data geometry.
