G027 Analysis of Travel-Time and Attenuation Anisotropy in Walkaround and Walkaway VSPs from Tiguentourine Field Algeria E. Liu* (British Geological Survey) M. Chapman (British Geological Survey) & S.R. Tod (BP) SUMMARY Theoretical models predict that both travel-time and attenuation anisotropy can be used to derive information about the fracture network. In this paper we analyse a range of azimuthally varying attributes from walkaround and multi-azimuth walkaway VSP data from a fractured gas reservoir in Algeria. Anisotropy is detected in both dynamic and kinematical attributes and reasonably consistent estimates of the fracture strike direction are derived. The magnitudes of the effects
