APPLICATION OF HYBRID GATHERS FOR RAPID DETERMINATION OF SEISMIC ACQUISITION PARAMETERS

摘要

In accordance with the present invention, a method is disclosed herein which is primarily designed for use in improving the seismic data collection process (210) through the use of hybrid gathers(318). The instant invention is suitable for application either in the field during seismic acquisition as part of the process or back at the main processing center, although it will probably be of greatest use in the field. That being said, the computational efficiency of the instant method and its ability to work effectively with low fold seismic data sets argue that it would be most useful in the field. By timely application of the instant method it is possible to improve or optimize the selection of acquisition parameters such as geophone spacing, line layouts, shot locations, instrument filters, etc., while the data are being acquired.
