Abstract
P096 THE EFFECT ON SEISMIC ANISOTROPY OF FLUID FLOW IN CRACKED MEDIA Abstract 1 Transfer of fluid between connected cracks may occur during the passage of seismic waves. Such fluid flow can be modelled using an extension of effective medium theory (Hudson et al. 1996) and is effected via non-compliant pores. The flow is governed by a parameter τ representing the relaxation time of pressure equalization between cracks. However if the cracks are fully aligned and have the same aspect ratio the theory produces the unexpected result that at low frequencies the cracks are effectively isolated and at high frequencies
