Time-lapse seismic requires estimation of 4D changes that are often smaller than the noise level. Hence, data processing and noise suppression are the key steps for time-lapse analysis. We propose a method for noise suppression and regularization of prestack data. The method is based on the local stack of spatially coherent events along the traveltime surfaces defined by the common-offset common-reflection-surface traveltime operator. Since the data are stacked locally, we don't harm amplitudes and phases of the signal. The coefficients in the traveltime approximation have a definite physical meaning which allows us to enhance particular types of waves. By the example of cross-well dataset we demonstrate, that the proposed method efficiently suppresses random noise, enhances the desired signals and increases the repeatability of the data. The overall benefit is a more reliable estimation of time-lapse changes, providing a more reliable information for enhanced oil recovery or other applications. The proposed stacking technique is not limited to cross-well observation geometries and can be extended to 2D/3D OBN and VSP datasets.","PeriodicalId":325587,"journal":{"name":"80th EAGE Conference and Exhibition 2018","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134525027","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}

High-resolution P-Cable 3D seismic data were acquired in this area with an inline separation of 6 m, a source frequency range of 5–350 Hz and an source-receiver offset range of 120–160 m. Seabed images derived from the P-Cable data show an increased resolution and sharpness compared to images from conventional 3D seismic and multibeam echosounder data. High-resolution images of the buried Upper Regional Unconformity (URU) were derived from the P-Cable data, revealing previously unrecognized structures such as hill-hole pairs and rhombohedral and transverse ridges. These observations indicate different subglacial thermal regimes, the presence of permafrost, and a strong link with variations in the underlying geology. No reflections are imaged within the intraglacial sediment package in the conventional seismic data. However, reflections interpreted as the top of a shear margin moraine, shear planes, mass transport deposits, and soft beds are visible in the P-Cable data. Meter-scale glacial landforms and layers identified in the P-Cable cubes comprise new information about glacier dynamics, fluid flow, and faults, which are valuable for geotechnical and geohazard evaluations of offshore infrastructure.","PeriodicalId":325587,"journal":{"name":"80th EAGE Conference and Exhibition 2018","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134361557","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}

Process-oriented models are more accurate than empirical trends because they simulate compaction and the kinetics geochemical reactions while accounting for composition, texture, and burial history. Additionally, they incorporate models of other rock properties such as permeability and seismic velocities. Although process-oriented models have had considerable success, they do not depict the geometry of sandstones at the pore and grain scale. “Digital sedimentary petrology” models, now under development, consider the 3D geometrical evolution of solids and pores in response to composition, texture, and burial history. These models simulate diagenetic processes with greater rigor compared to existing process-oriented models and provide input for “digital rock physics” simulations that until now have relied upon scanned physical samples. The hope is that coupling these simulation methods will make it possible to accurately predict properties of interest in geomechanics, structural deformation, seismic interpretation, petrophysical analysis, and reservoir simulation for areas away from well control.","PeriodicalId":325587,"journal":{"name":"80th EAGE Conference and Exhibition 2018","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131615871","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 only significant discoveries have been made in the Upper Permian carbonate play on the Loppa High area, whereas the more immature lowermost Permian carbonate play may trap significant volumes of hydrocarbons. During 2018, three new wells are planned to drill into the Lower Permian strata in the Barents Sea. Aker BP operates one, and participates in another of these. Aker BP have allocated significant effort and resources to enhance in-house understanding and to mitigate Paleozoic play risks in the NBSS. De-risking workflow can be split into three main parts; 1) Collection and detailed analysis of analogous field data from Svalbard archipelago to quantify and predict type of hydrocarbon source rocks present in similar depositional setting as interpreted from seismic data 2) Utilizing different seismic data imaging techniques to enhance seismic imaging and facies and lithology prediction of prospective reservoir levels 3) Incorporating all available data in Petroleum Systems Modelling (PSM) to assess the petroleum charge and preservation risk The resulting enhanced understanding of subsurface have facilitated positive drill decisions outside the present discoveries.","PeriodicalId":325587,"journal":{"name":"80th EAGE Conference and Exhibition 2018","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130823332","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}
