Achieving an understanding of all of the methods and concepts used during the interpretation process can be a daunting task. A partial list of disciplines incorporated into a complete interpretation includes rock physics, signal processing, wireline log analysis, computer visualization, structural geology, stratigraphy and petroleum engineering. Few, if any, new hires have mastered, or perhaps even been exposed to, all of these disciplines during their university education. Other, more experienced, petroleum professionals may have become specialists in one of these or other fields, and lack the big-picture view necessary for maximizing the value of a seismic interpretation.

By the end of this course, delegates will be able to:

• • Explain fundamental aspects of seismic wave propagation, diffractions, and reflection criteria
  • Compare 2D and 3D seismic acquisition techniques; evaluate key survey requirements necessary to achieve project objectives
  • Assess the importance of key seismic data processing steps including datum and statics corrections, velocity analyses, migration and depth imaging
  • Contrast 2D and 3D seismic data benefits, recognize common imaging pitfalls
  • Explain how prospect risk factors can influence project objectives and interpretation workflows
  • Demonstrate practical interpretation skills; construct and use synthetic seismograms, perform well-seismic ties, 2D line correlation, horizon and fault identification, seismic picking and basic mapping
  • Compare seismic time-to-depth conversion techniques and recognize the advantages and disadvantages of different methods
  • Determine factors affecting seismic resolution at the reservoir scale
  • Differentiate the various types of seismic attributes available and select appropriate attributes for a given project
