These provinces comprise the North Sea Oil Province, the North Sea Gas Province, the Irish Sea and the Atlantic Margin (Figure 4). The remaining and future petroleum potential of...
Oil and gas generation began locally in the North Sea Graben Province by Cretaceous time and has continued in various places ever since. Reservoirs are found in strata with ages ranging from Devonian to Eocene. Pre-rift reservoirs are found in fault-block structures activated during rifting and can be of any age prior to the Late Jurassic.
Geological controls on petroleum plays and future opportunities …
2022年3月1日 · Despite being found after the initial oil discoveries in the province, the honor of being the first North Sea oil producer belongs to the Permian (Rotliegende and Zechstein Group) reservoirs of Argyll field, with the first oil on stream via a tanker in …
Reserve growth in oil fields of the North Sea - GeoScienceWorld
2005年5月1日 · Increases in successive annual estimates of recoverable crude oil volumes indicate that oil fields in the North Sea, collectively and in each country, experience reserve growth. Specific patterns of reserve growth are observed among countries and primary producing reservoir-rock types.

2009年7月8日 · The Upper Jurassic Kimmeridge Clay (KC) and its Norwegian equivalents (i.e., Mandal, Tau and Draupne) are the most prolific petroleum source rocks in the northern North Sea, sourcing the...
Kimmeridgian Shales Total Petroleum System of the North Sea Graben Province
Extensional tectonics and failed rifting are fundamental to the distribution of oil and gas in the province. Accordingly, the geologic history and reservoir rocks of the province are considered in the context of their temporal relationship to the principal extension and rifting events.
The North Sea including the Danish Central Graben is a mature oil province where the primary source rock is composed of Upper Jurassic – lowermost Cretaceous marine shales.
3D seismic and 3D CSEM data from the Troll Western Oil Province. The presented methodology results in 3D distributions of effective porosity and hydrocarbon saturation. The estimated reservoir property distributions correlate with expected production effects, and we show how hydrocarbon volumes can be assessed. Introduction
Geology and hydrocarbon provinces of the North Sea
The oil and gas occurrences in the central and northern North Sea are tied to Mesozoic and Tertiary sediments; the gas fields of the southern North Sea are mainly contained in Permian series.The proven hydrocarbon provinces cover at best one third of the total area of the…
Reserve growth in oil fields of the North Sea
Increases in successive annual estimates of recoverable crude oil volumes indicate that oil fields in the North Sea, collectively and in each country, experience reserve growth. Specific patterns of reserve growth are observed among countries and primary producing reservoir-rock types.
