The presentation gives an introduction to the CHIMNEY project and study area. Data from 2 sources (GI guns and Surface sparker) are analysed, giving rise to measurements of attenuation as a function of two-wave time, azimuth and frequency at two locations. The data are inverted using a rock physics model, and probability distributions for matrix permeability and fracture size at the two sites are developed. Reference: Bull, J. M. (2018).
