N2 - Seismic wave attenuation Q∧<-1> is directly related to fractured rocks through scattering and fluid-related mechanisms, which are caused by fractures and pore fluids. This makes seismic attenuation a good parameter for studying fractured reservoirs. However, getting an accurate estimate of Q<-1> from 3D surface seismic data is challenging. This is due to the immaturity of the methodology which is mainly suitable for zero offset seismic data. In this study we established a new workflow to overcome such limitation. The seismic attenuation profiles estimated from geophone data acquired in an oilfield located in Abu Dhabi an emirate of the United Arab Emirates, show a sensitivity to oil-saturated zones.
