Salt
proximity surveys measure seismic energy propagating
through and reflected from salt structures. Data is used
to map complex salt surfaces in areas where surface
seismic data yield ambiguous results or are unavailable.
Due to the complex 3D structure of salt bodies,
traditional 2D salt proximity methods are inadequate in
mapping these structures accurately. Baker Atlas’
proprietary 3-C, 3D Salt Proximity interactive software
utilizes the full wavefield particle motion with 3D models
to accurately position the salt-sediment interface point
in 3D space. |
