Dr. Luc Ikelle

Professor

Ph.D., Paris 7 University, 1986

Research specialty: petroleum seismology

Luc T. Ikelle is Robert R. Berg Professor in the Department of Geology and Geophysics and director of the Center of Automated Seismic Processing at Texas A&M University. Earlier, he worked at Cray Research Inc. in Minneapolis, developing 3D seismic inversion algorithms for the CRAY Inc., Y-MP. From 1988 to 1997, he worked as a scientist at Schlumberger Geco-Prakla, Schlumberger Doll Research, and Schlumberger Cambridge Research. Ikelle earned a DEA (Diplôme d'Etudes Approfondies) and a Ph.D. in geophysics and geochemistry from Paris 7 University in France. He received the Le Prix de These du CNRS in 1986 for his Ph.D. thesis. His research interests include looking at ways of automating seismic data processing for reservoir definition and monitoring. He is co-editor of Anisotropy 2000: Fractures, Converted Waves, and Case Studies and is a member of AGU, EAGE, SEG, and APS - member of the Editorial Board of Journal of Seismic Exploration, SEG Representative-at-large.

Research:

  • Finite difference modelling of seismic waveforms (including anisotropy and attenuation).
  • AVO (Amplitude variations with offsets) and AVAZ (Amplitude variations with azimuths) formulation and analysis of OBC, VSP and streamer data Multiple (free-surface and internal) attenuation of OBC, Vertical Cable, VSP and streamer data.
  • Seismic processing with anisotropy.
  • Velocity analysis of OBC and streamer data.
  • Survey designs for OBC, streamer and VSP data.
  • Integration of EM data, reservoir flow data and seismic data.

Projects:

Consortium on Automated Seismic Processing (CASP) Our objective is to demonstrate that an automated seismic data processing system is feasible and can extend the seismic resolution window. (http://casp.systekproof.com/)
