Event Description

Reducing Infill Requirements Using Fresnel Zone Binning* and Steerable Streamers  
 
Historically it has become accepted that in 3D surveys that the adequacy of fold coverage a survey is assessed by sampling the survey in “bins” and then examining how many traces, and with what offset distribution, fall into each of the survey bins. In marine 3D’s such binning analysis is commonly used in the field to assess whether infill data is required. However, the dimensions of the conventional bins are usually based on the assumption that the traces within these bins will be stacked together. When pre-stack migration is part of the processing scheme, the traces which are stacked are the traces which are output from pre-stack migration and a different coverage assessment may be appropriate.  
 
 For a typical marine 3D seismic survey, infill shooting may be as much as 25% or more of the total cost of prime seismic acquisition. By combining the use of an alternative method involving Fresnel zone computation for assessing subsurface coverage, with steerable streamer control, infill can be significantly reduced. Over the last 12 months, these ideas have been developed into a working onboard system that optimized  infill reduction using the combination of Fresnel zone binning fold and coverage assessment techniques with steerable streamers. The background ideas will be described, and some examples from recent real 3D surveys shown.

Biography

 Dave Monk is the Director of Geophysics at Apache Corporation. Dave is responsible for worldwide seismic activity including acquisition and processing in areas such as: Argentina, Australia, Canada, Egypt, North Sea and the domestic USA. Having completed a Ph.D. in physics, he worked on seismic crews in Nigeria for two years, and has subsequently been involved in seismic processing and acquisition in most parts of the world. Monk has received “best paper” awards from the Society of Exploration Geophysicists and the Canadian SEG, and was recipient of the Hagedoorn Award from the European Association of Exploration Geophysics. He was the first vice president of SEG in 2006.
