Gulf of Mexico Offshore
For the past 20 to 30 years, the seismic industry has been working hard, attempting to build the perfect tools for Gulf of Mexico imaging. Fortunately, Tomography and Gaussian Beam have proven to be the most accurate seismic imaging tools available for the Gulf of Mexico today. Compared to published results, In-Depth’s Tomo and Beam technologies have produced superior images.
Tomography takes dense and non-hyperbolic picks and produces high resolution sediment velocity models. Our proprietary k-semblance produces dip-guided semblance that speed up the tomographic inversion. These characteristics are especially suitable for solving complex issues in the Gulf of Mexico.
Our speedy Gaussian Beam is peerless for building salt models. Gaussian Beams are many times faster than Kirchhoff and excellent in imaging large dips including steep salt flanks. Gaussian Beam naturally handles turning rays and multipathing, for imaging sediment and salt flanks–areas where Kirchhoff fails.
For base of salt model building, RTM is needed for its high fidelity of image quality. RTM can also generate angle gathers for subsalt velocity tomographic updating.
For salt model building, our Interactive Imaging provides a very powerful workflow by verifying different salt structures quickly and cost-effectively.
Finally In-Depth’s tomography, beam, and RTM are all capable of dealing with anisotropy. In the Gulf of Mexico, it is crucial to estimate anisotropy in order to tie the wells and flatten the gathers. TTI is also extremely important for a good estimation of volumetrics.
