Abstract: The present invention relates generally to a method of seismic data processing which provides a superior method of removing or attenuating some forms of seismic noise and can also be used as a basis for seismic attribute analysis and automatic trace editing. In particular, the present invention is directed toward the application of a Very Short-Time Fourier Transform (VSTFT) to seismic data, coupled with a novel approach to organizing and/or displaying the transformed data, so as to provide highly localized frequency analyses of seismic reflection events. The present invention utilizes a very great number of short overlapping Fourier transform windows, together with a Gaussian weight or taper function, to produce a plurality of near single-frequency "sub-band" traces for each seismic trace so analyzed. Although the present invention can be applied to a single seismic trace, it is preferably applied to a collection of seismic traces that are spatially related. Among the many uses of the transformed seismic data are selective removal of coherent noise events, analysis for seismic attributes related to subsurfaces features of interest, seismic trace creation by interpolation, and automatic identification and removal of noisy seismic traces.

Abstract: Compositions for scavenging oxygen are disclosed. These compositions comprise condensation copolymers comprising predominantly polyester segments and an oxygen scavenging amount of polyolefin oligomer segments. The polyester segments comprise segments derived from typical bottling and packaging polyesters such as PET and PEN. The copolymers are preferably formed by transesterification during reactive extrusion and typically comprise about 0.5 to about 12 wt.% of polyolefin oligomer segments. The copolycondensates are capable of absorbing at least 0.4 cc of oxygen per gram of copolymer in the solid state at ambient temperatures and are typically used as layers in films, liners, cups, wraps, bottles, etc. Use of these oxygen scavenging compositions in bottles provides a clear and rigid bottle similar in appearance to unmodified polyester bottles. In a series of preferred embodiments, bottles fabricated with the oxygen scavenging copolycondensates of this invention are over 99.4 wt.% polyester and suitable for recycle with other polyester bottles.
