In this contribution we document underpressure both onshore Svalbard and in the northern part of the Norwegian Barents Sea. Furthermore we discuss the potential geological processes contributing to the underpressure generation and the implications to petroleum exploration. Underpressure of up to 50 bar is observed onshore Svalbard and in five of the northernmost wells of the Barents Sea, with the former equating to some 50% of hydrostatic pressure at approximately 850 metres depth. Basins, including the study area, where naturally occurring underpressure has been documented share several common geological features; most notably all have undergone recent uplift. Whilst previously documented cases of underpressure have been observed in elevated onshore basins, underpressure on the Barents Shelf occurs below sea level. The combination of detailed onshore well and outcrop observations from Svalbard’s Longyearbyen CO2 lab and outcrops, and numerous offshore exploration wells in the northern Barents sea provide insight into the different potential underpressure forming mechanisms.","PeriodicalId":325587,"journal":{"name":"80th EAGE Conference and Exhibition 2018","volume":"13 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":"116373103","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}

In the adaptive geological model, the number of layers of its grid does not exceed the number of layers identified by the results of detailed correlation, while all model parameters are constructed depending on seismic data. The grid of the adaptive hydrodynamic model completely coincides with the geological grid without upscaling. In the adaptive hydrodynamic model, the system of differential equations describing the filtration process is solved according to the rules of the theory of percolation and cellular automata. The adaptive hydrodynamic models are always history matched. Calculation of the adaptive hydrodynamic model allows generating the distribution of remaining oil reserves and reservoir pressure. Using the adaptive hydrodynamic model, it is also possible to evaluate the development strategies of the reservoirs, using the iterative fuzzy-logical method to determine the oil decline rates first, and then to solve the system of equations for the interference of the wells. The proposed adaptive models are not simplified, they are complex and requires practically the same run time as their deterministic analogues. However, the adaptive models are easier and cheaper for users.","PeriodicalId":325587,"journal":{"name":"80th EAGE Conference and Exhibition 2018","volume":"113 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":"124159702","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}

Particularly, SO42- ions contained in injection water not only decrease electrical potential of rock surface, but also retain stability of polymer chain. Therefore, it is essential to analyse the potential of sulfate on oil production in LSWPF. From the results of viscosity analysis and zeta potential measurement of polymer solution, it was confirmed that Ca2 yielded precipitation with polymer molecule, leading to viscosity reduction, while SO42- stretched the polymer chains. In the results of coreflooding experiments for LSWPF, injecting polymer solution containing higher concentration of sulfate with neutral pH revealed less degradation and affected wettability alteration, resulting in enhancing oil recovery. In overall, we demonstrated the interaction between low-salinity waterflooding and polymerflooding, especially the impact of sulfate ions on polymer degradation and consequently enhanced oil recovery. In field application of low-salinity polymerflooding method to carbonate reservoir, pH and PDI of injection water should be designed in advance to maximize the oil recovery.","PeriodicalId":325587,"journal":{"name":"80th EAGE Conference and Exhibition 2018","volume":"46 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":"128028686","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}
