Paper Summary
This paper will examine the results of reprocessing a legacy 2D dataset. Imaging improvements will be shown to have been achieved both through the use of time domain signal enhancement techniques, as well as through the use of TTI anisotropic prestack depth migration. Furthermore detailed interpretation of the primary geologic interfaces that are associated with strong velocity contrasts was crucial in building an accurate velocity model. Anisotropic tomography at well locations in addition to extrapolation of the Thomson’s parameters along 3D consistent geologic boundaries served to further improve the consistency of the resultant seismic images.
