Abstract

The purpose of this talk is to highlight essential procedures for production of seismic sections for site survey interpretation. Other papers at this conference will concentrate on the use of individual techniques such as attribute analysis etc.. The main problem with high resolution gas hazard surveys is the very short turnaround time, and therefore it is essential that the processing procedures are correct and that no spurious effects are introduced.

It is particularly important to produce accurate sections if the subsequent use of workstations is envisaged during the interpretation stage. The interpreter must know and understand what has been done to the data he is working on.

A brief discussion of acquisition of the data will be presented from the processing point of view. Emphasis will be on the provision of information to the processing house which can save a lot of time and potential errors.

Also of crucial importance is the role of those responsible for onboard QC who, if they do not understand the principles of seismic acquisition, may not make the correct decision when circumstances out of the ordinary arise.

An account of some essential QC techniques will be presented, along with examples of correct and incorrect ways of applying some of these procedures.

Finally, these topics are clearly illustrated using a typical example of a “bright spot”, and some useful characteristics and information one can derive if the time and resources are made available.
