It has made advances in classification, pattern recognition and process modeling. It is well know that shaly formations gives some effects on the reservoir as reduction in storage capacity by reducing effective porosity and reduces the ability to transmit fluids by lowering permeability. The presence of clay in a reservoir has two effects on petrophysical logs: lowers resistivity and it causes the porosity logs (sonic, neutron and density) to generally record too high a porosity (Asquith, 1990). For neural application, the back propagation network was used, taking as reference the well logging and core data from three wells of Namorado Field of Campos Basin (Brazil) Finally, and error analysis was done taking the permeability values obtained from cores as reference.","PeriodicalId":332941,"journal":{"name":"Proceedings of the 16th International Congress of the Brazilian Geophysical Society&Expogef","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132361675","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}

However, during the seismic acquisition, operational obstacles cause the acquired seismic data to be irregular, containing distortions and gaps. This irregular sampling impairs several stages of seismic processing such as imaging, elimination of multiple, migration and inversion. Interpolation and regularization methods can solve both missing data and irregular sampling. Thereby, the regularization of seismic data is an important problem to be addressed. As we intend to show in this work, the common reflection surface method for common offset (CO-CRS) with global attributes search strategy is a good alternative for regularization, since it can reconstruct traces from the acquired data and also is capable of improving the definition of reflection events existing in the data.","PeriodicalId":332941,"journal":{"name":"Proceedings of the 16th International Congress of the Brazilian Geophysical Society&Expogef","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128107666","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}

The greed algorithm is used to fill in empty bins, generated by defective sampling, under statistical and/or physical constraints, so as to achieve an acceptable Fourier spetrum. Much like in other implementations, a least square norm Fourier spectrum is the input for the process. Here, this least square initial solution is provided by the AIDFT. The greed algorithm proposed is an iterative procedure that consists in, step by step, correcting for survey’s footprints of main Fourier components.","PeriodicalId":332941,"journal":{"name":"Proceedings of the 16th International Congress of the Brazilian Geophysical Society&Expogef","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134256977","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}
