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

EAGE Madrid 2015: Creating a 3D Geologic Model for 2D Depth Migration in the Peruvian Andes

pdf_icon

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
