CSEG Recorder 2017: Myanmar PSDM case history

pdf_icon

Vestrum, R.W., Gonguet, G., and MacArthur, T., 2017, Geologically Constrained Anisotropic Depth Imaging in the Central Burma Basin, Onshore Myanmar, CSEG Recorder.

  • 2D seismic imaging along the foothills of the Indo-Burma range
  • Interpretive geologic constraints required for model building in noisy seismic data
  • Resulting seismic images showed structural details that time processing could not fully image.

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

pdf_icon

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

Vestrum, R.W., Vilca, J., Di Guilo Colimberti, M., 2015, Creating a 3D Geologic Model for 2D Depth Migration in the Peruvian Andes, 2015 EAGE Conf & Exhibition, Madrid, Spain.

  • Consistent velocity model across multiple 2D lines by building the velocity model in 3D
  • Interpretive 3D velocity model minimized misties at line intersections
  • Final PSDM results removed subthrust velocity pull-up

Vestrum, R.W., and Gittins, J.M., 2009, Technologies from foothills seismic imaging: replacements or complements?: First Break, 27, no. 2, 61-66.

  • The editor describes this paper: “Our land seismic section begins with a provocative article challenging the assumption that only new technologies will do.”
  • Sven Trietel suggests that this philosophical discussion “ought to be made ‘must’ reading for any newcomer to our game.”

  • This case history shows the unpredictable nature of imaging below for lateral-velocity heterogeneity and seismic anisotropy. The surprise ending shows how the imaged structures move as we correct for each wave-propagation effect.
