ABSTRACT Behavior of sediment gravity flows can be influenced by seafloor topography associated with salt structures; this modify the depositional architecture deep-water sedimentary systems. Typically, salt-influenced successions are poorly imaged in seismic reflection data, and exhumed systems rare, hence detailed sedimentology stratigraphic these remains understood. The Triassic (Keuper) Bakio Guernica bodies Basque–Cantabrian Basin, Spain, were active during sedimentation. diapirs grew...

This paper presents an integrated seismic, petrophysical and core facies study of the Mey Sandstone Member Central North Sea Lista Formation. Seismic mapping attribute analysis reveal that is composed distinct axial lateral routing systems. In turn, system can be divided into coeval western eastern fairways defined by underlying graben topography in a similar manner to overlying Sele Formation (Forties) sandstones. These trends are confirmed analysis, which also reveals systems not as...

Abstract This introduction briefly outlines the potential impact of igneous processes on sedimentary basins and their energy resources. The associated volume includes contributions across a range scales; from margin-wide rifting to impacts reservoir quality. systems elements such as tectonics, heat flow, hydrocarbon (and other) fluid charge, structuration reservoirs are reviewed with direct exploration production, geothermal carbon capture storage projects. A strong understanding these...

Abstract This study presents an integrated seismic, well and core-based analysis of the Maureen Formation in Central Graben North Sea. Facies reveals that it is possible to divide sandstones into amalgamated, sand- mud-prone divisions, but related chalk facies are complex imply a range depositional processes including pelagic fallout, debris flows turbidity currents. These deposits have impact on interpretation amplitude-based seismic attribute volumes. Detailed petrophysical mapping,...

Lower crustal intrusion is considered to be a common process along volcanic or magma-rich passive margins, including the NE Atlantic Margin, where it thought have occurred during phases of Paleogene magmatism, both prior and continental break-up between NW Europe Greenland. Evidence magmatism prevalent throughout sub-basins Faroe–Shetland Basin as extensive lava flows pervasive suites igneous intrusions. However, in contrast with other areas located no lower reflectivity indicative has been...

Abstract Detrital garnet suites have been demonstrated to be reliable indicators of the mineralogical and lithological characteristics sediment source areas. This study applies analysis Paleocene Eocene Sele Formation deep-water sandstone units central North Sea. These stratigraphic are economically important as they represent one main hydrocarbon reservoir intervals in this mature basin. The routing turbidity currents into Central Graben has related axial fans (ultimately sourced from...

Abstract A review of recent Triassic research across the Southern Permian Basin area demonstrates role that high-resolution stratigraphic correlation has in identifying main controls on sedimentary facies and, subsequently, distribution hydrocarbon reservoirs. The depositional and structural evolution these successions was product polyphase rifting controlled by antecedent structuration halokinesis, fluctuating climate, repeated marine flooding, leading to a wide range reservoir types...

Abstract An analysis of the Lower Triassic ‘Buntsandstein’ gas play in underexplored Mesozoic rift system German–Danish Horn Graben is presented. Dry hole information from four well penetrations analysed alongside development a 3D basin model. It demonstrated that dry holes do not preclude existence working hydrocarbon system. Reservoir and seal elements are present, although details quality distribution uncertain. Carboniferous coal preservation likely, limited area, within graben can be...

This paper presents an integrated seismic, petrophysical and analogue core study of the Mid-Eocene Grid deep-water Sandstone Member from Nelson Field area, Central North Sea. Two possible turbiditic units were identified in seismic data. 1 shows channel-like features and a complex stratigraphy whilst 2 consists scattered bright amplitude events (shown to be slumped shales chalky limestones by cuttings analysis). Lower Eocene Tay Member from nearby Gannet provided analogue for...

The Faroe–Shetland Basin (FSB) is one of the only significant exploration frontiers remaining on UK Continental Shelf. Over half basin's discovered reserves and resources lie along two intra-basinal highs, Corona Ridge Rona Ridge. In contrast to Ridge, central-northern has received much less attention. To reveal new insights into geology, structural configuration hydrocarbon prospectivity we analyse 3D seismic data from wells 213/23-1 (Eriboll), 214/21a-2 (South Uist) 213/25c-1V (North...

The sub-basalt domain of the Norwegian continental shelf (NCS) is one last remaining hydrocarbon exploration frontiers in Europe. While there an established geological and tectonic framework, little has been published that addresses risks/uncertainties. Unlike Faroe Shetland Basin Rockall Trough, at time writing, are currently no industry-drilled well penetrations on shelf. Numerous potential Mesozoic plays exist NCS but, due to lack penetrations, a perceived large risk. By using...

A series of offshore intra-basinal igneous centres have been documented across the North Atlantic Igneous Province including UK, Ireland and Greenland. However, inconsistent cross-border terminology implies that similar features are not present in Norwegian offshore, which, turns, leads to misperceptions geological differences. This paper presents evidence for a suggests consistent non-genetic terminology. In Møre Basin, several sit close continent–ocean boundary (COB), which previously...

Abstract Subsurface salt flow can deform overlying strata and influence contemporaneous sedimentary systems. Studying salt‐sediment interactions is challenging in the subsurface due to poor imaging adjacent salt, field dissolution of halite. Discrete Element Modelling provides an efficient inexpensive tool model stratigraphy deformation around structures, which advantageous over other modelling techniques as it realistically recreates brittle processes such faulting. Six 2D experiments were...

It is generally accepted that hydrocarbon exploration in northern Europe has reached a mature stage. A basin’s maturity defined by the underlying number of new discoveries and declining production rate fields (SPE 2015). For geoscientists, basin well-defined characteristics terms of, for example, reservoir presence or trap formation (e.g. Byrne 2012). interesting, therefore, to note how much still unknown about certain stratigraphic intervals Europe. The Mesozoic overburden Southern Permian...

Sediment gravity flow behaviour is influenced by seafloor topography associated with salt structures, which controls the depositional architecture of deep-water sedimentary systems. Typically, salt-influenced successions are poorly-imaged in seismic reflection data and exhumed systems rare, hence detailed sedimentology stratigraphic these remains poorly understood. The Triassic (Keuper) Bakio Guernica bodies Basque-Cantabrian Basin, Spain were active during sedimentation. diapirs grew...

Abstract The ability to predict coal units from seismic data has become important for hydrocarbon exploration, especially in areas away traditional play sweetspots. An understanding of distribution/thickness can influence the risking basin source-rock presence/charge efficiency. A selection wells is presented Carboniferous Elbow Spit Platform (Netherlands), Mid North Sea High (UK) and adjacent areas. These penetrated various thicknesses, as well sandstones, mudstones thin limestones...

Summary The Faroe–Shetland Basin (FSB) is one of the only significant exploration frontiers remaining on UKCS and will continue to contribute indigenous oil gas supply throughout next 40 years. Over half reserves resources discovered within FSB are situated Corona Rona Ridge. However, in contrast Ridge, as January 2023, none discoveries made along Ridge have been sanctioned for development. Throughout last 20 years, success has largely limited Paleocene–Eocene-aged reservoirs around Rosebank...

Igneous processes within sedimentary basins impact energy resource plays across a range of scales from regional tectonics to reservoir porosity. Understanding these interactions has direct influence on hydrocarbon, carbon capture, geothermal, hydrogen and helium projects. This volume demonstrates state the art thinking around often complex systems.

<p>Complicated structural-stratigraphic traps at the salt-sediment interface have historically hosted large hydrocarbon discoveries. Understanding sediment-routing around active salt bodies, is now vital for carbon capture and storage projects due to being a ‘near-perfect’ seal. Despite advances in subsurface visualisation, remains difficult image steep-bedding, bed-thickness changes lithological contrasts. Outcropping examples provide depositional...
