Exhumation Of The North Atlantic Margin

This book includes a selection of oral and poster presentations from "Onshore-Offshore Relationships on the Nordic Margin Conference" held in Trondheim in 2002. The conference was jointly arranged by the Norwegian Geological Society (NGF) and the Norwegian Petroleum Society (NPF), and attempted, through different thematic sessions, to bridge the gap often noted between industry and academic research. The first part of the conference included presentations under the theme "Basement control on offshore structuring" with representative articles from that segment included in this book and covering topics that range from analysis of vertical movements of basement substrates to the deep structural architecture of the Norwegian Sea to the development of the Jan Mayen microcontinent. These papers set the scene for the second segment of the conference, "Linking uplift and erosion with subsidence and deposition", that in the present book include articles related to the Triassic to Present-day infill history in the Norwegian and northern North Seas. The last segment of the conference addressed "New challenges" with respect to natural features of the deep-water areas that necessitate particular consideration and innovation on the part of research and industry to mitigate risk and maximize returns from field development. In this book, the articles addressing this theme present analyses of the enormous submarine slides that took place during the Holocene in the Norwegian Sea, and are of particular interest to the developers of the Ormen Lange gas field; other articles address the occurrences of gas hydrates in the near sea floor and the challenges presented in identifying and protecting the Lophelia cold-water reefs in the region. * Processes creating the structural framework for the deposition and depositional patterns in the Norwegian Sea and northern North Sea * Erosion and subsequent deposition of sediments in the subsiding deep-water basins in the Norwegian Sea area and northern North Sea * Challenges the oil industry has met in the deep-water areas of the Norwegian continental shelf

Permo-Triassic Salt Provinces of Europe, North Africa and the Atlantic Margins: Tectonics and Hydrocarbon Potential deals with the evolution and tectonic significance of the Triassic evaporite rocks in the Alpine orogenic system and the Neogene basins in the Iberian Peninsula, North Africa, and the western Mediterranean. As the nature of the Triassic evaporite sequences, the varied diapiric structures they feed, and the occurrence of hydrocarbons suggest that the Triassic evaporites represent an efficient system to trap hydrocarbons, this book explores the topic with a wide swath, also devoting content to a relatively unexplored topic, the mobilization and deformation of the Triassic salt in the western and northern Tethys (from Iberia and North Africa, Pyrenees and Alps, Adriatic and Ionian) during the subsequent Alpine orogenic processes. The book includes chapters updating varied topics, like the Permian and Triassic chronostratigraphic scales, palaeogeographic reconstructions of the western Tethys since the Late Permian, the petroleum systems associated with Permo-Triassic salt, allochthonous salt tectonics, and a latest revision of salt tectonic processes in the Permian Zechstein Basin, the Atlantic Margins (from Barents Sea, Scotia, Portugal, Morocco, and Mauritania), the Alpine folded belts in Europe, and the various Triassic salt provinces in North Africa. The book is the go-to guide for salt tectonic researchers and those working in the hydrocarbon exploration industry. Presents the first reference book to cover salt tectonics of Permo-Triassic period rocks Features case studies of passive margins like the Barents and the North Sea, Greenland, Nova Scotia, offshore Mauritania, Morocco and Iberia, and folded belts like the Betics-Rif, Tell, Pyrenees, Atlas Mountains, Alps, Balkans, Apennines, the Adriatic and Ionian Seas, and the Zechstein Basin in Norway, the UK, the Netherlands, Germany and Poland Integrates field observations, seismic examples, well-log data and models developed in universities with highly technical and advanced subsurface studies developed by the petroleum industry

Investigating the complex interplay between tectonics and sedimentation is a key endeavor in modern earth science. Many of the world's leading researchers in this field have been brought together in this volume to provide concise overviews of the current state of the subject. The plate tectonic revolution of the 1960's provided the framework for detailed models on the structure of orogens and basins, summarized in a 1995 textbook edited by Busby and Ingersoll. Tectonics of Sedimentary Basins: Recent Advances focuses on key topics or areas where the greatest strides forward have been made, while also providing on-line access to the comprehensive 1995 book. Breakthroughs in new techniques are described in Section 1, including detrital zircon geochronology, cosmogenic nuclide dating, magnetostratigraphy, 3-D seismic, and basin modelling. Section 2 presents the new models for rift, post-rift, transtensional and strike slip basin settings. Section 3 addresses the latest ideas in convergent margin tectonics, including the sedimentary record of subduction intiation and subduction, flat-slab subduction, and arc-continent collision; it then moves inboard to forearc basins and intra-arc basins, and ends with a series of papers formed under compessional strain regimes, as well as post-orogenic intramontane basins. Section 4 examines the origin of plate interior basins, and the sedimentary record of supercontinent formation. This book is required reading for any advanced student or professional interested in sedimentology, plate tectonics, or petroleum geoscience.

The Norwegian Continental Shelf (NCS), focus of this special publication, is a prolific hydrocarbon region and both exploration and production activity remains high to this day with a positive production outlook. A key element today and in the future is to couple technological developments to improving our understanding of specific geological situations. The theme of the publication reflects the immense efforts made by all industry operators and their academic partners on the NCS to understand in detail the structural setting, sedimentology and stratigraphy of the hydrocarbon bearing units and their source and seal. The papers cover a wide spectrum of depositional environments ranging from alluvial fans to deepwater fans, in almost every climate type from arid through humid to glacial, and in a variety of tectonic settings. Special attention is given to the integration of both analogue studies and process-based models with the insights gained from extensive subsurface datasets.

Geomechanics investigates the origin, magnitude and deformational consequences of stresses in the crust. In recent years awareness of geomechanical processes has been heightened by societal debates on fracking, human-induced seismicity, natural geohazards and safety issues with respect to petroleum exploration drilling, carbon sequestration and radioactive waste disposal. This volume explores the common ground linking geomechanics with inter alia economic and petroleum geology, structural geology, petrophysics, seismology, geotechnics, reservoir engineering and production technology. Geomechanics is a rapidly developing field that brings together a broad range of subsurface professionals seeking to use their expertise to solve current challenges in applied and fundamental geoscience. A rich diversity of case studies herein showcase applications of geomechanics to hydrocarbon exploration and field development, natural and artificial geohazards, reservoir stimulation, contemporary tectonics and subsurface fluid flow. These papers provide a representative snapshot of the exciting state of geomechanics and establish it firmly as a flourishing subdiscipline of geology that merits broadest exposure across the academic and corporate geosciences.

Great effort has been undertaken to investigate potential geohazards in relation to the development of the Ormen Lange gas field offshore Mid-Norway. The field is located in the scar left after the giant, tsunami-generating Storegga Slide, which occurred roughly 8200 years ago, and the slide risk has consequently received particular focus. The studies have been multi-disciplinary in character, and have involved a number of companies, universities, and research institutions. The results of the project led to a significant advance in the understanding of the Storegga Slide in particular, and submarine slope instability in general, and played an important role in the approval of field development by Norwegian authorities. This book comprises 26 individual contributions representing the wide span of topics addressed in the project. The main scope is to provide a state-of-the-art report on geohazard investigations in a high latitude continental margin setting. Most of the data and results published in this book would not have reached beyond the confidential report stage unless the license partners of the Ormen Lange license had agreed that this information deserves a wider audience. Multidisciplinary and covers most themes treated in slope stability studies prior to the field development phase Provides a link between basic research and applied geohazard studies, with direct relevance for risk evaluation in relation to field development activities, such as pipeline design, drilling of wells, structure foundation etc. A state-of-the-art report on geohazard investigations in a high latitude continental margin setting in relation to field development activities
