Russian Arctic shelf opens broad opportunities for oil and gas fields’ development andhydrocarbon potential for the years to come. Among a number of other fields, the Prirazlomnoyeoilfield is a unique one, as it is the only one currently being under development.
A 36-years field development project has been applied since 2014; and already this daynumerous studies on revealing of new potentials within the Pechora Sea water area are gettingmore relevant. In this connection, specialists consider more ancient reservoirs lying beneath thePermian and Carboniferous deposits which, in turn, are put into development.
It is Silurian deposits which represent one of the keys for effective hydrocarbon extraction. Theways on how to produce petroleum they entrapped within millions of years were offered in thiswork. Conceptual solutions were undergone qualitative and qualitative analyses made by theauthor based on a number of articles, technological schemes, open sources and supplementaryinformation gained from Gazprom Neft Shelf specialists.
In the paper it was presented a description of the geological structure of the Prirazlomnoye field,qualitatively assessed of the filtration and reservoir characteristics of productive Silurianreservoirs and the properties of oils; considered lithology, stratigraphy, tectonics, hydrogeology,geocryology. In addition, the current field development scheme was considered, and an analysiswas made of winterization issues. Finally, development options were proposed, final solutionswere selected and justified with recommendations.
The results achieved would in absolute terms acquire professional significance for fieldengineers, geophysicists, project managers and other specialists involved in the oil and gasindustry.
