Title: Some Recent Advances in Exploration Geophysical Techniques and Data Previous HitProcessingNext Hit: ABSTRACT

Author(s): Edward F. Zagst, Charles L. Robinson

Article Type: Meeting abstract


The geophysical industry has made significant advances in the past 2-3 years, changes which have altered the exploration programs of many companies. Some of the more conspicuous areas of new advances in present-day geophysical exploration techniques and dataprocessing procedures are discussed in this presentation.

The common depth point, or CDP, technique of field operations is one of the most important changes in procedures of recent years. This operation is discussed in some detail. Of equal importance is the rapid emergence of the use of Previous HitdigitalNext Hit recording in the field and the use of the Previous HitdigitalNext Hit computer in playback operations. The use of these concepts allows the geophysicist to determine the parameters of the problems of deghosting, deconvolution, dereverberation, and optimum filtering much more efficiently than the present-day analog method. Present-day high-speed analog-to-Previous HitdigitalNext Hit converters are now available which allow the Previous HitdigitalNext Hit computer playback programs to be applied to the old seismic data now in the files of many companies.
