question for Professionals about 3-D Seismic

I understand on 3-D Seismic you see a "Bright Spot" for Nat Gas--- If this is true can you get a estimate about quantity that is in the formation or only just the Seismic will tell you simply  Nat Gas  is there. Can operator predict if well will be good gas well or not based on seismic ?

I think you are correct, Joe. I just don't know what the different colors represent.

If I remember right the shot points were red and white streamers and the data points were blue and white. That may vary with different crews though.

Yes Your right, Joe. I guess just wait now , & see what happens if anything. I think they know its there but , there's a whole on it somewhere's.

Thank You For Your knowledge !,

In certain areas 3D seismic can be a very accurate indicator that gas is present (sometimes as high as 75% success rate). However, it is very difficult to determine the thickness of the productive zone which, of course, directly affects how "good" a well will be.

Hi Bob, we where told it is under the, Tusculusa Fault, it runs right through the middle of where we have property . I Pray, it does have that 75%. I could help a lot of people. Do I have to wait on someone to call me? Are, do you know who I can get in touch with? Please let me know.
Thank You , for your reply. Much appreciated .

JRC,

Patience, patience. Just wait for them to call you. If they are interested they will let you know.

Bob-- Thanks for reply-- so it can be used to correlated if you have a offset well but not necessary if a "wildcat"  will be good well or not . Is 3-D very accurate indicator in Shale formations?

What I was told several years ago is that the knowledge and experience of the Geophysicist that does the  programming for the interpretation of the data has a lot to do with how the information appears on the printout.   We have had a number (6) of Wilcox wells drilled in the last 5 years in the area and all have been dry holes. They were drilled on 3-D seismic data. So nothing is a sure thing, not even 3-D data.
