You could try approaching the oil companies and ask them if they have anything they could give you for a school project. They are normally very keen to help and should be able to give you "anonymous" information, that is with the field or well information removed or it could be from an old well or field.



Normally seismic is shot across an area before wells are drilled and then periodically during production to measure efficiency of production (called 4D seismic as it incorportates time) but you can shot a seismic log of an individual well using wireline logging tools. For these you'd need to approach someone like Schlumberger Wireline or Baker Atlas, who in turn would need to contact the oil company.



You should be able to find contact details on the companies websites.

The two options are a "seismic cross section" near the well and a "sonic log" of the well. The cross section is "sort of" an image of a slice of the earth. The log is a graph of the velocity of sound in the rocks at each depth.



Call the nearest university with a petroleum engineering department. They can fix you up with some of their teaching materials. The ideas of calling oil companies or well service companies are good ones too. Don't forget that your state has a geological survey that might help.

Are you talking about before the well is drilled? Such a seismic record would be for the reservoir not a single well.



For a single well you might have a sonic log.
