Thread: Why make well to seismic tie??

  1. Why make well to seismic tie??

    I have little question,
    I know that we have to make well to seismic tie and extract a proper wavelet but realy i don't know why we do this step in seismic interpretation as i think the most important thing is the extraction of the wavelet but to make tie i don't know why tie seismic with wells, what type of information i can get from well to seismic tie?

    Thanks,

  3. look, i think we do well to seismic tie to get additional informations like( quality of seismic data + streching / shifting seismic events to its correct position + determination of main markers and finally for wavelet extarction as you said before.

    Looking forward another answer....

    and on depth domain will help use to calculate are of prospect hidyrocarbon.

    Re: Why make well to seismic tie??

    there are two main reasons for well to seismic tie , first for conventional seismic data (2D/3D) interpretation , second for unconventional seismic interpretation (AVO , Inversion)
    first , you get from well to seismic tie :
    1-correct T-D relation
    2- definition of seismic markers , and understanding seismic character ( polarity and phase)
    3- understanding the stratigraphic relations through your seismic line (facies variation ... etc )
    4- multiples recognition (not very easy)

    second , in unconventional seismic interpretation ... well to seismic tie is the first step for determenistic wavelet extraction ... which is the main step in seismic inversion
