The method is based on representing the inhomogeneities as secondary sources defined on dense auxiliary grids. Interaction of the secondary sources with the finite di erence scheme is performed by interpolation. We observe good agreement of the method’s results with precise solutions for simple models in 2D.","PeriodicalId":158800,"journal":{"name":"SEG Technical Program Expanded Abstracts 2018","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124530739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During SH-wave simulation, the spatial derivatives of the new developed first order SH-wave equations are transformed into wavenumber domain and a staggeredgrid Fourier pseudospectral time-domain method is used to obtain discretized forms of these wavenumber operators, which in turn, effectively eliminates the Gibbs phenomenon. The first order velocitydisplacement SH-wave equations also make it possible to set hybrid perfectly matched layers around computational boundaries to mitigate artificial reflections. This new scheme is applied for wavefield modeling in two-layer heterogeneous media. Comparisons of simulation results with pseudo-spectral method using second-order SH-wave equation further verify its accuracy. Finally, SH wavefield simulation in a three-dimensional over-thrust model is illustrated.","PeriodicalId":158800,"journal":{"name":"SEG Technical Program Expanded Abstracts 2018","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128130160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
