Course description

Applied Seismic Anisotropy for Fractured Reservoir Characterization - ASAF

The course is designed to enable you to perform professional geophysical work to evaluate fractured reservoirs and/or reservoirs that require hydrofracturing to produce. The emphasis of the lectures is steered to the participants' work assignments. Field data case histories and laboratory data illustrate the principles and practices of calibrating azimuthal travel times and azimuthal prestack amplitudes against independent measurements of in-situ horizontal stresses, and natural fractures that flow fluids.

The course covers acquisition design and Q/C, azimuthal processing, interpretation, and modeling to test different interpretations.

 

The skills that you will learn will also involve integrating the support data - well logs, production testing, VSP, core work - with your reflection seismic data. Each section of the course is supported with a classroom exercise.

Suitability - Who should attend?

Geophysicists assigned to evaluate fractured reservoirs; also, geoscientists assigned to evaluate resource plays hydro-fractured for production. Multicomponent seismology, as well as azimuthal P-P, is offered in the course, because the recording of both the P- and the S-wave is extremely beneficial for fractured reservoir analysis and/or resource plays. The introductory lectures are also suitable for geologists and reservoir engineers who wish to know how seismic data can help them to understand the 'plumbing' of the reservoir and the in-situ stress state of the reservoir. The course is designed for the working interpretation geophysicist/geo-scientist, who is assigned to evaluate reservoir(s).

Training Course Content

  • Fundamentals of seismology: body waves that travel through a solid medium
  • reflection, refraction, mode-conversion; Fundamentals of seismic anisotropy. P-P multi-azimuth, P-S multi-azimuth, S-S multi-azimuth
  • Fundamentals of 3D full-azimuth seismic data acquisition; issues of cost, number of channels, geophones chosen, recording system, fold, etc.
  • VSP acquisition
  • multicomponent acquisition
  • Fundamentals of seismic data processing: P-P multi-azimuth, P-S multi-azimuth, S-S multi-azimuth
  • requirements for processing sequences
  • necessity to comprehend the (chosen) contractor's definition of 'azimuth' and checks throughout processing to determine if the contractor is adhering to its definition of azimuth
  • Fundamentals of seismic data interpretation for fractured reservoir analysis, and in-situ stress evaluation
  • commercially available software needed for multi-azimuth and/or multi-component 3D seismic interpretation
  • Fundamentals of seismic data modeling for anisotropy, common (different) assumptions within different modeling packages
  • Commercially available support data: where to find it, how to integrate the required support data
  • Additional topics by request (end of each day)
