 W-17: Seismic Diffraction Methods for Fault and Fracture Detection SEG 2012 Annual Meeting Technical Program
Date: Friday, 9 November 2012
Time: 8:30 am – 4:00 pm
Location: Mandalay Bay Convention Center, Room: Breakers D
Organizers: William Burnett, Evgeny Landa, Tijmen Jan Moser, Michael Pelissier, and James Schuelke
Through the support of the SEG Research Committee
Description
Faults, fractures, pinchouts, inclusions and other small scale subsurface heterogeneities give rise to a diffraction response. Seismic diffraction imaging is a rapidly emerging technology with great potential to reduce exploration and production risks and increase recovery, particularly in unconventional plays such as shale gas. Seismic reflection is the response to continuity in the subsurface, whereas seismic diffraction is the response to discontinuity. The synergy between the reflection and diffraction methods can be exploited to reduce uncertainties in subsurface definition. The workshop format will include a range of presentations by invited speakers, covering the basic geology of reservoir scale faults and fractures, fracture modeling, and the theoretical and applied components of seismic diffraction. Each presentation will be followed by a discussion. This will be followed by a general discussion session.
