SEG/AAPG IMAGE ’23 case history from Camisea Perú

pdf_icon

Vestrum, R.W., Soldo, J., Zunino, E., Muzzio, M.E., Chung, J.F., 2023, Geologically constrained model building for seismic depth imaging in Camisea, Perú, The International Meeting for Applied Geoscience & Energy, Houston, USA.

  • Integrated seismic case study from the Peruvian Andes
  • Geologic constraints are essential to seismic imaging in complex-structure land areas
  • Seismic reflectors on the final depth image matched well depths across the block without vertical scaling after migration
  • Revised volume redefined the structural model and revealed an additional subthrust target

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

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.

2011 First Break: 3D case history from the Himalayan foothills of Pakistan

pdf_icon

Vestrum, R.W., Dolgov, V., Wittman, G., Csontos, L, and Gittins, J., 2011, 3D seismic imaging over two structurally complex seismic surveys in the foothills of Pakistan: First Break 29, no. 4, 61-70.

  • Time processing and merge of two 3D surveys over highly complex geology.
  • Illustrates our back-to-basics workflow where no single technology stood out in the processing, but careful attention to details in fundamental processes created a readily interpretable seismic volume.

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.
