Hi there,
could anybody help me how to manage it that I can integrate shallow borehole data (up to 500 m depth) with interpreted stratigraphic and seismic information into 3D seismic data which was depth-converted using internal NMO velocities? I am using Petrel and my idea was to prepare a velocity model using the NMO velocities which then needs to be adapted to match the seismic data and the intepreted borehole data. There is no sonic or density logging data from the wells available. Also no check-shots.

But how to adjust the velocity model? Is there some interpolation tool available to get use of the stratigraphic data from about 150 old boreholes of the 5x5 km array?

Thanks for any hints how to go ahead with Petrel!!
Best
