At the present time, Cretaceous carbonate platforms can be found in very different geotectonic domains of the Mediterranean area, from rift basins to thrust belts. The most promising reservoirs have been often involved in orogeny deformation or occur at various depths in subsurface, hindering the search for analogues of the Zohr structure that could help to better understand the HC potential of this new Eastern Mediterranean play. An analysis and comparison between the more than 30 shallow water domains that characterized the Western Neotethys during Cretaceous was performed on the basis of paleolatitude, size of the platform and position in respect to emerged land, in order to find potential analogues for the Zohr-like platforms of Eastern Mediterranean. Among the selected analogues, one of the most interesting is the Bagnolo Platform, which hosts the Bagnolo in Piano oil field and develops entirely in the in Emilia Romagna region (Italy) subsurface.","PeriodicalId":213700,"journal":{"name":"Eastern Mediterranean Workshop 2018","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122720246","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}

As an example, vertical movements of water-gas contacts smaller than a meter can be detected under some circumstances. Seafloor subsidence monitoring uses water pressure measurements at the seafloor as a starting point. Once the required tide corrections are applied, the method reaches accuracies as low as 2 mm, depending on the field conditions. Subsidence is a required correction for the interpretation of gravity results, and it is by itself a valuable monitoring tool, sensitive to important reservoir and overburden properties. It is directly related to pressure depletion and lateral compartmentalization, and in some cases, it is a key factor for the safety of the installations. In this abstract, we review the principles of the 4D gravity and subsidence monitoring technology. We then discuss some field cases from the Norwegian Continental Shelf that illustrate the value that this type of data provides for reservoir management. Finally, we discuss what are the drivers of the cost of the technology and what steps are taken by the industry to reduce cost, and hence to make it feasible in more fields.","PeriodicalId":213700,"journal":{"name":"Eastern Mediterranean Workshop 2018","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134376243","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 such contingency, re-processing with modern techniques all the accessible seismic surveys, even if very old, helps to retrieve the maximal information on the subsurface, fostering the decision-making process and the de-risking of successful exploration activities. The main objective of the presented study is the broadband processing of a technically- and geologically-challenging vintage marine 3D dataset from the Mediterranean Sea, via modern Pre-Stack Time Migration. The main geological target for the reprocessed dataset is represented by fractured Jurassic limestones. Severe seismic challenges are posed by the obsolete and unconventional acquisition pattern, along with the multiples and reverberations offered to the seismic image by the shallow-tilting and high-impedance Messinian salt/evaporites. The authors hereby present a modern, innovative, and rigorous broadband re-processing for the improved imaging and illumination of the subsurface, applicable to all Mediterranean provinces.","PeriodicalId":213700,"journal":{"name":"Eastern Mediterranean Workshop 2018","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133421845","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}

This study focuses on the deposition of clastic sediments during the Messinian Salinity Crisis, in the South-West Exclusive Economic Zone (EEZ) of Cyprus, highlighting the potential prospects of the Messinian low-stand incised valley/submarine canyon play and taking into consideration the salt tectonics of the region. After the interpretation of 2D seismic data, the results show that the Messinian clastic sediments derived from the River Nile during the forced falling regressive system tract (FFRST) deposited strictly west of the West Eratosthenes High in the deep Herodotus Basin and have a thickness of approximately 2 km in South-West EEZ of Cyprus. These clastic accumulations represent the distal sand sheets of the Nile Cone and are important regarding the petroleum plays in the area. Finally, the northern gliding of the Messinian Evaporites from the Nile Cone to the deep Herodotus Basin was controlled by the Pre-Messinian topography and can justify the absence of any bathymetric scar from the west side of the Eratosthenes Continental Block (ECB).","PeriodicalId":213700,"journal":{"name":"Eastern Mediterranean Workshop 2018","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115447035","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 western Greece, the Ionian islands provide a lot of information with regards to the most external parts of the Hellenides Thrust-and-Fold Belt (TFB). In addition, several wells and a dense seismic grid confirm the geological knowledge of the area and mitigate the uncertainty about the petroleum system there. In contrast, the area south of Crete includes only four (4) very small islands providing scattered information of the geological setting in the Cretan margin, along with a sparse seismic grid and the lack of wells. Despite more than forty (40) years of geological and geophysical work in the region, the geodynamic and tectonic processes have been debatable and controversial. An initial attempt to distinguish and outline the geotectonic zones present in the area south of the island of Crete has been done based on the integration of seismic data and onshore geology. However, because of the above-mentioned limitations the attempt remains speculative. The use of the seismic data allowed for a more accurate mapping of the three (3) distinct geological areas south of Crete; Cretan margin, Backstop and Mediterranean Ridge. The Cretan margin includes stacked nappes similar to those onshore Crete, the Backstop includes probably the most external Hellenides, while the Mediterranean Ridge cannot be assigned to any of the known Hellenides.","PeriodicalId":213700,"journal":{"name":"Eastern Mediterranean Workshop 2018","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131417704","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}

Choosing the right scale and complexity of a model is critical for performing an effective and efficient geomechanical analysis. In this paper different geomechanical modeling techniques are compared for their accuracy and efficiency using a relatively simple (continental slope) and a more complex geological setting (submarine canyon). This was done by comparing the resulting state of stress of 1D well-centric geomechanical models with those of reservoir-scale 3D geocellular and 4D finite-element models. The more complex submarine canyon model shows that in relatively complex areas the 1D and 3D geomechanical models no longer give accurate stress results and a 4D model is needed to accurately simulate the state of stress. On the other hand, the continental shelf model shows that in a simple geological setting creating a 1D wellbore-scale geomechanical model is an efficient and effective way of calculating stress. The paper concludes that the initial step in a geomechanical study is assessing the geomechanical application of the model, taking the complexity of the geological setting into account and based on that assessment choosing the modeling complexity that is necessary to get accurate results, without unnecessarily spending resources.","PeriodicalId":213700,"journal":{"name":"Eastern Mediterranean Workshop 2018","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133178810","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}
