Over recent years, many authors have proposed to compensate the absorption loss effects inside of the imaging process through the use of an attenuation model. This is necessary in the presence of strong attenuation anomalies. Q tomography has been de

The analysis of S wave polarization from a large number of aftershocks of the 1992 Erzincan earthquake has revealed a clear S wave splitting, which we interpret in terms of seismic anisotropy in and around the Erzincan basin and which concerns at lea

Summary The computation of velocity by tomography using Residual Move-Out (RMO) curves is widely used in the industry. The semblance-based, automatic dense picking of RMO has proved to be a very efficient technique for conventional data. However, in

Well-aligned or “flat” events are key for high quality amplitude versus offset or amplitude versus angle fitting. In the context of marine 3D and 4D processing we have recently reported (MacKenzie et. al, 2004) on our efforts to improve gather qu

Summary The focusing process for time imaging is improved drastically when high-density parameter fields are used. Large offsets, steep dips and finally the anisotropy of the subsurface revise the bases of time processing. Today, two parameters are r
