Computer modelling of clustured airguns
Authors R.M. Laws, L. Hatton and M. HaartsenIt is much cheaper to design an airgun array by using computer simulation rather than by performing numerous field trials. However, you must be sure that the sirnulations are accurate. The use of computer simulation is now well established in the design of conventional, 'weakly interacting' arrays where the airguns are over about one metre apart (Ziolkowski and Metselaar 1984).

The <i>N</i>th root slant stack - a new method of coherency enhancement
By S. KravisThe forward transformation has been used in velocity inversion procedures for both reftected and refracted arrivals (Stoffa et al. 1981; Schultz 1982) as it is able to make use of both pre-critical and post-criticaI arrivals. By transforming common midpoint gathers into the tau-P domain, the process of normal moveout (NMO) correction and stacking becomes one of summing along an elliptical rather than a hyperbolic trajectory (Kelamisand Mitchell 1989).
