An inverse Q-filtering procedure attempts to remove the Q-effect to produce high-resolution seismic data, but some existing methods either reduce the S\/N ratio, which limits spatial resolution, or generate an illusory high-resolution wavelet that contains no more subsurface information than the original low-resolution data. In this paper, seismic inverse Q-filtering is implemented in a stabilized manner to produce high-quality data in terms of resolution and S\/N ratio. Stabilization is applied to only the amplitude compensation operator of a full inverse Q-filter because its phase operator is unconditionally stable, but the scheme neither amplifies nor suppresses high frequencies at late times where the data contain mostly ambient noise. The latter property makes the process invertible, differentiating from some conventional stabilized inverse schemes that tend to suppress high frequencies at late times. The stabilized inverse Q-filter works for a general earth Q-model, variable with depth or traveltime, and is more accurate than a layered approach, which involves an approximation to the amplitude operator. Because the earth Q-model can now be defined accurately, instead of a constant-Q layered structure, the accuracy of the inverse Q-filter is much higher than for a layered approach, even when implemented in the Gabor transform domain. For the stabilization factor, an empirical relation is proposed to link it to a user-specified gain limit, as in an explicit gain-controlling scheme. Synthetic and real data exam-ples demonstrate that the stabilized inverse Q-filter corrects the wavelet distortion in terms of shape and timing, compensates for energy loss without boosting ambient noise, and produces desirable seismic images with high resolution and high S\/N ratio.<\/jats:p>","DOI":"10.1190\/1.2192912","type":"journal-article","created":{"date-parts":[[2006,6,9]],"date-time":"2006-06-09T19:13:16Z","timestamp":1149880396000},"page":"V51-V60","source":"Crossref","is-referenced-by-count":346,"title":["Inverse\n                    <i>Q<\/i>\n                    -filter for seismic resolution enhancement"],"prefix":"10.1190","volume":"71","author":[{"given":"Yanghua","family":"Wang","sequence":"first","affiliation":[{"name":"1Imperial College London, Centre for Reservoir Geophysics, Department of Earth Science and Engineering, London SW7 2BP, United Kingdom.
