AAPG ICE Barcelona 2016: Impact of a tightly folded anisotropic layer on imaging in Papua New Guinea – a modelling study

Cameron, G.H., Gillam, D., and Vestrum, R.W., 2016, Impact of a tightly folded anisotropic layer on imaging in Papua New Guinea – a modelling study. AAPG ICE, Barcelona, Spain.

  • FD acoustic anisotropic modelling quantifies the imaging problem resulting from tight folds in the near surface
  • TTI PSDM is sensitive to the model dip
  • Surface-geology measurements helped constrain model dip

AAPG ICE Barcelona 2016: Lithostatic-load effects in geologically constrained model building for foothills anisotropic seismic imaging

pdf_icon

Vestrum, R.W., Cameron, G.H., and Vestrum, Z.E., 2016, Lithostatic-load effects in geologically constrained model building for foothills anisotropic seismic imaging. AAPG ICE, Barcelona, Spain, 325-325.

  • Lithostatic load is another geologic constraint we may apply to areas of low signal and high complexity
  • We create more lithologically consistent velocity models by separating out compression effect
  • More consistent models improves 3D mapping from 2D lines
