Data Processing Requirement for a Deep Towed Multi-Channel Array

摘要

Data processing of the deep towed seismic multi-channel array data can be accomplished by the proposed CDC Cyber 170 System and a dedicated sea going mini based computer system. Partitioning of the processing load into two categories, Interactive I/O limited and Computation Bound, makes it possible to use each system in a cost effective efficient manner. Demultiplex Edit and Static Operations can all be performed at sea using the mini based system. In addition, velocity analysis interpretation and seismic display can be performed on the system at the NORDA site. Computation based algorithms: Semblance Velocity Analysis, Normal Moveout and Stack, Migration Deconvolution, Band Pass Filtering, Amplitude recovery etc., can all be performed on the new CDC Cyber 170 system.
