It is the only known permafrost-bearing oil deposit in the US. Although several studies estimated 1.5 billion bbl of oil and 99 bcf of gas in the Umiat field, there is no commercial production to date. The shallow reservoir intervals in this field are filled up with permafrost (or frozen ground) and gas. Permafrost is affected by the presence of lakes, ponds, and streams, which have appreciable heat capacity. The presence of permafrost, gas, and ice lakes deteriorates the seismic data quality significantly. In this study, we reprocess the 3D seismic data and generate new seismic images that show prominent stratigraphy and structure, some of which were not visible before. The results reveal the presence of shelf-edges with strong amplitude anomalies at the shallow intervals and a structural high at the deep interval.","PeriodicalId":117371,"journal":{"name":"Seg Technical Program Expanded Abstracts","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123507127","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}

Due to this distinctive acquisition geometry, special attentions should be paid in processing and imaging the VSP data. Considering the fact that velocity errors are inevitable for field data application, it is better to utilize least-squares reverse time migration with subsurface offset extension (LSERTM) because of its good property of preserving data information in the extended domain. LSERTM has been actively studied for surface seismic data in academic research, but it is never reported with application to VSP data. We fill this gap by applying LSERTM to VSP data with a simple layered model, and analyze the behavior of the subsurface offset common image gathers (SOCIGs) and the angle domain common image gathers (ADCIGs). Numerical examples demonstrate that there are significant differences in the subsurface offset behavior between the VSP survey and the surface seismic survey. We conclude that the strategies functioning well in surface seismic processing workflow may not be suitable for direct application to VSP data.","PeriodicalId":117371,"journal":{"name":"Seg Technical Program Expanded Abstracts","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121709554","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}
