| Abstract: | The use of data file systems within the areas of geological well log and reservoir analysis is now accepted as a necessity in the storage and correlation of large volumes of diverse information. Multi-channel and three-dimensional seismic recording techniques of various types result in a situation where the amount of processing parameters and derived seismic properties of a trace are rapidly approaching the amount of the recorded data themselves. The requirement to access these statistics efficiently has introduced the problems of data management to the seismic processing community. Much software effort has been expended in the design of algorithms for cross reference and indexing of the statistics required in signal processing. These efforts, however, are generally in the direction of a localized solution to a specific requirement and tend to ignore the data base concepts well developed within the commercial data processing community. This paper examines the applicability of commercial data base concepts to the problems of data handling in the area of geophysical exploration, sets forth some basic definitions and organizational characteristics, and describes a system for the integration of several earth disciplines within a single data base from which parameters and mapped information may be derived and indexed for the purpose of processing and interpretation. |
