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.

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

AAPG Explorer: Why 2D lines do not tie when beds are dipping

pdf_icon

Vestrum, R.W., 2012, In overthrust settings, tie, tie (2-D) again, AAPG Explorer, August 2012, p 38.

  • Discusses the interpretation pitfall of trying to tie 2D lines
  • Offers a strategy to try to overcome the 2D line-tie problem.
  • Rob did not pick the title, it was set by the editor ;-)

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.”
