Basins Analysis and Petroleum Systems Modeling of Western Black Sea, Ukrainian Sector

The Ukrainian sector of the Western Black Sea (WBS) is one of the last remaining exploration frontiers in Europe. This area, which includes shelf to deepwater environments, is underexplored with no drilling of targets in water depths exceeding 100 meters. That is why, the Ukrainian sector of the WBS is attractive for exploration, especially in the context of new play types and targets such as biogenic gas. These hydrocarbon formations have been proven by neighboring Romania and Turkey in the areas adjacent to Ukrainian waters. Therefore, a rigorous Basin Analysis program has been initiated to assess the petroleum systems and play risks in the entire Ukrainian sector of the WBS. The goals of this program are: 1) to establish a regional geoscience foundation following best industrial practices in exploration; 2) to enable establishing more accurate risking and ranking procedures for an exploration portfolio and 3) to provide critical support for the analysis of a new generation of seismic data that is currently being acquired. In this paper the initial scope of work is presented.

Strategic Value of Basin Analysis Teams in Exploration – Applications in Ukraine

A proven approach in exploration management is to establish multi-disciplinary Basin Analysis (BA) Teams that follow industry best practices and standardized procedures to deliver geologic risk assessments to both management and asset teams. Team members have the ability to provide a combination of specific technical expertise that is used to develop long-term foundation knowledge of basins and plays, but at the same time enables them to react to management and asset team requests for rapid assessments such as block and prospect risking/ranking and investigations of specific geologic challenges. In this paper, we review requirements for the establishment of successful Basin Analysis (BA) teams and provide examples of methodologies, strategies and technical workflows that are being applied to address exploration challenges in the three main exploration target areas in Ukraine, the Western Black Sea (WBS), the Dieper-Donets Basin (DDB) and the Carpathians are in Western Ukraine. For each of these target areas, we provide an example of a BA Team strategy that is followed to address specific exploration challenges. The application of industry standard best practices in exploration by a dedicated expert team and close cooperation with asset and technical teams within the organisation ensures that these engagements will make an important contribution to improve the efficiency and success rates of exploration activities in Ukraine.

Features of generation, migration and accumulation of hydrocarbons in the eastern part of the Skythian plate

The article shows the main spatio-temporal regularities of the development of the processes of generation, migration and accumulation of hydrocarbon fluids in the eastern part of the Scythian plate. The authors studied the features of the generationaccumulation hydrocarbon systems of the northern platform side - the Karpinsko-Mangyshlak and East Ciscaucasian oil and gas regions based on the application of technologies of basin analysis and modeling of hydrocarbon systems. The research results indicate that the following hydrocarbon systems are distinguished in the sedimentary cover of the eastern part of the Scythian plate: Jurassic, Cretaceous, Paleocene-Eocene, and Oligocene-Miocene systems. Based on the results of the studies and modeling, the main directions of further prospecting and exploration work in the eastern part of the Scythian plate were determined. The study area was differentiated by the nature of the predicted oil and gas content, the age of the promising complexes and the confinement to tectonic structures and zones. Keywords: generation; migration; accumulation; hydrocarbons; Scythian plate; hydrocarbon systems; basin analysis; modeling; source rocks.

A Bacia do Itajaí-Açu pede Ajuda: Reações ao apelo

Resumo: O crescimento populacional de cidades que ficam localizadas nas margens dos rios tem como uma das consequências a sua poluição, recebendo dejetos agrícolas e industriais, lixo doméstico e esgoto sem tratamento. Os rios da Bacia do Rio Itajaí-Açu, que tem nas suas margens cidades como Blumenau e Brusque, no estado de Santa Catarina, fazem parte do estudo, pela sua importância na Região do Vale do Itajaí. O artigo abrange o histórico e localização da bacia; análise de reportagens sobre poluição da bacia; descrição e análise de três projetos que com ações de conscientização através da educação ambiental nas escolas, nas comunidades e envolvimento de autoridades públicas e empresários. A metodologia empregada foi a pesquisa de reportagens em jornais regionais, artigos científicos, relatórios e material iconográfico. Impossível afirmar que a poluição da bacia do rio Itajaí-Açu desapareceu, mas as diferentes ações evidenciaram a importância do envolvimento de diferentes atores da comunidade como aliados na preservação. Palavras-chave: Vale do Itajaí. Rios. Lixo. Projetos. Preservação THE ITAJAÍ-AÇU BASIN ASKS FOR HELP: REACTIONS TO THE APPEAL Abstract: The population growth of cities that are located on the banks of rivers has as one of the consequences its pollution, receiving agricultural and industrial waste, domestic waste and sewage without treatment. The rivers of the Itajaí-Açu River Basin, which has on its margins cities such as Blumenau and Brusque, in the state of Santa Catarina, are part of the study, due to its importance in the Itajaí Valley Region. The article covers the history and location of the basin; analysis of reports on basin pollution; description and analysis of three projects that with awareness actions through environmental education in schools, communities and involvement of public authorities and entrepreneurs. The methodology used was the research of reports in regional newspapers, scientific articles, reports and iconographic material. It is impossible to affirm that the pollution of the Itajaí-Açu river basin has disappeared, but the different actions have highlighted the importance of involving different community actors as allies in preservation.

Marine gas hydrates’ evolution after Middle Pleistocene: basin analysis of the Danube fan, Black Sea

The aim of this work is to reconstruct the variations of the total gas hydrate (GH) masses of the Danube deep-sea fan after 0.265 Ma BP. The PetroMod™ model developed in GEOMAR, Germany is for basin analysis of the Western Black Sea for 98 Ma. Geological structure is from 2D seismic of the Black Sea consortium “Geology without limits”. Results show a trend for total GH masses decrease after Middle Pleistocene and the role of the GHs as sink and source of methane.
