AAPG ICE 2019: Geologically constrained seismic imaging in Andean thrust belts

pdf_icon

Vestrum, R.W., 2019, Geologically Constrained Anisotropic Depth Imaging in Andean thrust belts, AAPG ICE, Buenos Aires.

  • Seismic data in structured land areas have severe limitations
  • Geologic interpretation and human collaboration can overcome these limitations
  • Examples from Colombia and Peru show how we resolve these issues through geoscience collaboration
  • Increased accuracy of an imaging algorithm also means increased sensitivity: PSTM → PSDM → RTM

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

Vestrum, R.W., Florez, I.C., and Gittins, J.G., 2009, Anisotropic depth migration in the Colombian Llanos Foothills as a key to understanding the structure in depth: 2009 AAPG ACE, Denver, USA.

  • 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.
