Use of Full Azimuth Seismic and Microseismic for Unconventional Plays - FAMS

May 28, 2014

For surface Seismic, participants will learn to evaluate azimuthal seismic in fractured reservoirs or resource intervals needing hydro-fracking. The course presents reflection seismic and microseismic acquisition-design, processing, interpretation, and integrating support data - narrow-azimuth seismic, well logs, production tests, VSPs, and core work.For microseismic, participants will learn the strengths, weaknesses, limitations, and benefits of microseismic imaging of hydraulic fractures.

For surface seismic, experienced geoscientists working seismic to evaluate unconventional resources, and/or fractured reservoirs that require hydraulic stimulation. For microseismic, all professionals using microseismicity to plan, monitor, evaluate, and diagnose stimulations will find this course useful.

You will Learn:

Participants will learn how to:

  • Specify what geologic and/or engineering questions need to be asked about your reservoir and your play
  • Specify the geophysical data that need to be acquired; design acquisition; specify the processing sequence
  • Interpret the final processed data & test different interpretations
  • Identify the support data required for the successful fracture and in-situ horizontal stress characterization
  • Extract engineering benefits and meaning from microseismic data
  • Appraise the utilities, capabilities, and limitations of microseismic imaging
  • Develop insights and fundamental questions for microseismic projects
  • Identify the support data needed to give a complete picture of the results
  • Weigh field deployment options
  • Assess stimulation designs
