Introduction

The model defined in Seabed for 3D seismic acquisition concentrates only on the data collected and not of the acquisition activity. The purpose is to store the seismic data collected during the 3D acquisition for retrieval for seismic processing or for the purpose of archiving the data for later use. The data collected can be seismic data, navigation data, reports of acquisition, and any other ascii data in the form of files. The seismic data is mostly in SEGD form, the navigation data is in UKOOA P1 form, and reports can be either ascii or binary files.

For a completeness of the data stored in the model, Acquisition 3D Seismic requires Seismic_Survey, Survey_3D, and Acquisition_3D describing the survey; R_Cartographic_Ref_System referring to projection used at the time of the survey; Seismic_Boundary defining the extent of data in spatial coordinates; Business_Associate describing the ownership of the survey; and Geophysical_Inventory containing the collection of data files.
