报告题目：Characterizing fracture induced permeability in a gas chimney using frequeney-dependent anisotropy
报告内容简介
Gas chimneys are zones ofenhanced permeability, typically associated with high levelsof gas flux, but many of the mechanisms involved are unclear. Recent work in the Uk hasfocussed on characterizing a gas chimney in the UK through a unique anisotropy experimentThe proiect used Ocean Bottom Seismic with a variety of sources tuned to different frequenciesaiming to detect the frequency-dependence of anisotropy, Frequency-dependent anisotropy hasbeen tied theoretically to permeability and fracture scale lengths.
within the chimney and at a reference site. We measured shear-wave splitting and P-waveattenuation anisotropy, which varied markedly with frequency, with apparent correlation to fluidand fracture properties. Modelling ofthe results provided a plausible interpretation in terms ofthe fluid flow regime.
