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

2010 Geophysical Prospecting: Understanding anisotropic imaging problems

pdf_icon

Vestrum, R.W., and Lawton, D.C., 2010, Reflection point sideslip and smear in imaging below dipping anisotropic media: Geophysical Prospecting, 58, 541–548.

  • In folded and faulted geologic settings, dipping anisotropic strata above exploration targets blur and misposition imaged seismic reflectors. Correcting for these anisotropic effects can significantly reduce exploration risk.
  • Raytracing and numerical seismic models illustrate and quantify anisotropic imaging problems to show the importance of correcting for anisotropy in seismic imaging.

2009 AAPG Convention case history from Colombia with Isabel Florez at Hocol

  • 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.
