These factors can all create uncertainty when predicting pore pressure. Here are introduced two independent methodologies for present day shale pressure prediction across the Barents Sea, focussing in particular in the Southwestern Barents Sea where high overpressure is often recorded. Independent velocity log based and geological modelling based shale pressure prediction methods are used. Comparison of the two models generally shows good consistency in results, helping to validate the predictions and models and reduce uncertainty. This reinforces the need to integrate multiple techniques in order to reduce uncertainty in what is a challenging area for pore pressure prediction. The results also show that understanding the complex and variable burial history in each well is vital for pore pressure prediction, as this history defines the present day pressures. The models developed have clear implications for design of wells in the Barents Sea, and are also important for understanding reservoir overpressure variation (and potential reservoir fluid flow).","PeriodicalId":295902,"journal":{"name":"Second EAGE Workshop on Pore Pressure Prediction","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114565367","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}

Therefore, performing manual workflows for petrophysics, pore pressure and geomechanics prediction can be impractical due to turnaround considerations and the multiple personnel required. This, together with technical challenges of complex stratigraphy, multiple facies, variable rock properties, and the interaction of pore pressure and geomechanics, calls for more consistent, sophisticated, and faster analytical tools. A supervised deep neural network approach is presented as an innovative tool to devise solutions which simultaneously integrate myriad data types. Furthermore, an algorithm was developed to predict a certain number of attributes solely from a facies-based seismic inversion, namely Vp, Vs, and Rho. The application of these algorithms on various blind wells from a Permian Basin case study, both within and outside the seismic survey, shows a reasonable accuracy when compared to manually interpreted counterparts but were obtained in a fraction of the time, hence, provide a promising outlook for the application of deep learning in integrated studies.","PeriodicalId":295902,"journal":{"name":"Second EAGE Workshop on Pore Pressure Prediction","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125636660","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}

On one hand well planning requires the understanding of the pressure regime, on the other hand abnormal pressure conditions could affect the behavior of the petroleum system. The upper boundary of the overpressured zone was identified on wireline logs. Comparison of the pressure trends with the lithology sensitive logs suggested that the overpressure generation relates to shaly strata. Two sedimentary environments were formed during the Late Miocene sedimentation cycle where shale rich sediments were deposited: delta slope and foreground of turbidite systems. As the formation of abnormal pressure regime relates to low permeability sediments the main overpressure generation mechanism might be the non-equilibrium compaction. This theory is confirmed by the well log signatures of these sections. Beside the non-equilibrium compaction at least two other mechanisms could improve the overpressure, i.e., clay mineral transformation and lateral transfer. The basin modeling is an alternative methodology for the pressure regime investigation. A 3D basin model was built to test the technique. This approach allowed to investigate the effect of the lateral transfer and the hydrocarbon generation too. Furthermore, information about the timeframe of the overpressure emergence was gained.","PeriodicalId":295902,"journal":{"name":"Second EAGE Workshop on Pore Pressure Prediction","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131067976","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 Brazil, the Sergipe Sub-basin is located in the northeast of the country, corresponds to an Atlantic-type rifted basin with deep grabens controlled by large distensive rotational faults. The sub-basin represents one of pioneer and important areas of oil and gas production in this country with a renewed interest in the last decade for deep and ultra-deepwater opportunities. Despite that, the pore pressure in that area still little known. Thus, in these research we estimate the pore pressures throughout the stratigraphic units drilled by the P978-11 well, hoping in that way to contribute for future models of pore pressure in the basins of NE Brazil. For that, we applied on the sonic log of the P978-11 well the traditional Gardner and Eaton equations, but with own parameters values for the area, and then smoothed and calibrated the final results by loess regression. Four pore pressures zones were found ranging from 28 MPa to 89.4, suggesting an overpressure behavior in the Zonas 3 and 4.","PeriodicalId":295902,"journal":{"name":"Second EAGE Workshop on Pore Pressure Prediction","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121208003","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 study area consists in Santos Basin shallow waters and in Campos Basin deep waters. The settings are carbonate layers folded over anticlinal salt dome structures. An effort has been done to associate the wells pore pressure data with the carbonate layers structures interpreted from seismic sections. At each dome the Albian carbonate reservoirs are found at a local pore pressure regime either at normal or slight overpressure or at high overpressure. One possible way for a high pore pressure increase is lateral and vertical pore pressure transfer from a deeper interval down the flanks of the anticlinal dome structures. The pressure connection may be restricted just to the Albian or it may involve the pre-salt Aptian interval through salt windows around the domes. Another possible scenario for overpressure mechanism consists on oil or gas generation in the Albian. The prediction of the Albian carbonates pore pressure is necessary for well drilling design to both exploratory targets the post-salt and the pre-salt.","PeriodicalId":295902,"journal":{"name":"Second EAGE Workshop on Pore Pressure Prediction","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121598715","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}
