"Advanced Seismic Attributes & AVO for Reservoir Delineation" 

Program Goals

By the end of this training course, participants will learn to:

  • Use attributes to enhance subtle faults and folds, as lithological indicators, and quality control the choice of processing parameters.
  • Evaluate and exploit attribute expressions for different depositional environments to better characterize reservoirs by adopting appropriate workflows and multi-attribute tools.
  • Identify geological features highlighted by attributes, limits of attribute analysis on data that have been poorly imaged and good and bad color display practices.
  • Determine Seismic Wavelet Sensitivity Analysis.
  • Determine Seismic to Well Tie Sensitivity Analysis.
  • Apply RGB Color-Blending Spectral Analysis vs. Full Bandwidth
  • Conventional Seismic Attributes.
  • Apply Multi Attribute Display.
  • Analyze VSP data & Make Velocity Analysis
  • Separating between Fluid & Lithology using different methodologies; AVO, Inversion and other Techniques.
  • Generate Seismic Impedance Cube & Facies Cube (Gas Sand, Water Sand & Shale/Background).
  • Extract a Gas-Sand & Water-Sand Geo-bodies from Seismic data.
  • Analyze all the data to optimize the best Well location.
  • Evaluate and mature new Plays & Prospects.
  • Search for new Opportunities in Brown Fields.

How this course be presented?

The course will not only presented by showing and interpreting the material in detail, but also the participants will work together using a real Seismic data to apply all the workflow and to project their previous knowledge and experience onto the course, they also encouraged to bring their own data so that real working examples can be reviewed and interpreted.

Why Choosing This Program?

The primary objective of this course is to gain an intuitive understanding of the kinds
of seismic features that can be identified by 3D seismic attributes, the sensitivity of
seismic attributes to seismic acquisition and processing, and how independent seismic
attributes are coupled through geology. We will also discuss alternative workflows
using seismic attributes for reservoir characterization as implemented by modern
commercial software and practiced by interpretation service companies. Another main
objective is ti know and understand the differences between RGB Color-Blending
Spectral Analysis vs. Full Bandwidth Conventional Seismic Attributes, not only by
theoretical background but also by real exercises.
