Applied Micropalaeontology


Book Description

Seven original case-studies are presented in this volume, each describing the application of micropaleontology and palynology in applied geology: (1) a study of the modern distribution of coccolith sedimentation in the North Sea and its potential for future application in basin analysis; (2) ostracods are shown to be good paleoenvironmental indicators in the early Cretaceous and Tertiary; (3) a biogenic gas seep in the North Sea is shown to be marked by diagnostic benthonic foraminifera; (4) in the North Sea hydrocarbon exploration, integrated studies of micropaleontology have provided invaluable data; (5) palynofacies analysis are shown to be vital in determining depositional events and hydrocarbon source rock potential; (6) the application of paleontology and sedimentology to sequence stratigraphy is demonstrated in the early Cretaceous; and (7) the application of micropaleontology is shown to be an essential tool in both engineering and economic geology. Most chapters have been prepared by earth scientists from industry. The study of microfossils presented in this book provides invaluable data for stratigraphers, petroleum geologists and for engineers and economic geologists working in hydrocarbon exploration and basin analysis.




The Palynology and Micropalaeontology of Boundaries


Book Description

This volume explores geological boundaries in time and space using palynology and micropalaeontology. Boundaries produce distinct signatures in the micropalaeontological record. They can tell us much about the response of biotic systems to environmental change in both marine and terrestrial realms. Different microfossil groups and geological contexts require their own approaches, definitions and considerations of boundaries. The papers here cover the methodology of boundary identification from biostratigraphical, ecological and palaeoenvironmental perspectives.

Paleozoic Plays of NW Europe


Book Description

North Sea and onshore Netherlands and Germany, Paleozoic hydrocarbon plays across parts of NW Europe remain relatively under-explored both onshore and offshore. This volume brings together new and previously unpublished knowledge about the Paleozoic plays of NW Europe to describe significant additional exploration opportunities outside and below existing plays. The volume contains papers on Paleozoic plays in the North Sea, Irish Sea, onshore UK, France and Switzerland. They highlight how improvements in seismic data quality and the availability of previously unpublished well datasets form the basis for improved understanding of local to regional interpretations that move forward from generalized basin development models. The improved structural trap and source rock basin definition feeds to better constrained, locally variable burial, uplift, maturation and migration models. Particularly notable are the significant mapped extents and thickness of Paleozoic source, reservoir and seal rocks in areas previously dismissed as regional highs and platforms.




Sedimentary Environments Offshore Norway-Palaeozoic to Recent


Book Description

Required reading for geologists working in the offshore areas, Volume 10 continues the series from the Norwegian Petroleum Society. This work provides an up-to-date review of the late Palaeozoic to present sedimentary history of the Norwegian offshore areas in the North Sea and Mid-Norway basins. Case studies, overview articles and analogue examples from adjacent areas such as Greenland and Denmark, present new ideas on the development of the Norwegian margin from the Carboniferous through the Mesozoic and Cenozoic. In particular, new evidence and interpretations are presented on well-known major reservoir-bearing successions such as the Statfjord Formation and Dunlin Group in the Northern North Sea, and the Åre and the Tilje Formations in the Mid-Norway area. Furthermore, the Upper Jurassic succession in the Haltenbanken area is described, giving new evidence on the interplay between extensional tectonics and sedimentation during the second major rift phase in the area. The Cretaceous and Cenozoic periods are treated extensively, showing their importance as overall deep water sedimentary systems with proven and potential reservoir rocks, such as in the Ormen Lange Field, and for causing burial of Jurassic rocks to advantageous depths for hydrocarbon generation. The Recent sedimentary history of the Norwegian margin is treated with examples of the glacial history and giant submarine slides which understanding is vital for the placement of offshore installations. The book is organised based on geologic time, from Palaeozoic through Mesozoic to Cenozoic examples. It includes a set of palaeogeographic maps from the Carboniferous through to the Cenozoic. In addition, there are numerous examples of core photographs, well log data, correlation panels and seismic as well as outcrop photographs and logs from the analogue examples. Comprehensive reference and keyword lists are also included.




Sedimentary Organic Matter


Book Description

A sound understanding of the global carbon cycle requires an appreciation of the various physico-chemical and biological processes that determine the production, distribution, deposition and diagenesis of organic matter in the natural environment. This book is a comprehensive interdisciplinary synthesis of this information, coupled with an organic facies approach based on data from both microscopy and bulk organic geochemistry.




Sequence stratigraphy of the Jurassic–Lowermost Cretaceous (Hettangian-Berriasian) of the North Sea region


Book Description

Sequence stratigraphy has become a powerful tool in the basin analysis of the North Sea Basin, and will continue to play an important role in the maximization of the remaining hydrocarbon potential of the region, whilst also supporting the energy transition in carbon capture and storage projects with Jurassic storage units. This Memoir provides a long-awaited, comprehensive documentation of Jurassic to lowermost Cretaceous sequence stratigraphy of the region (UK, Norway, Denmark and adjacent areas). The volume is amply illustrated by numerous well log displays, core images, seismic lines, chronostratigraphic diagrams and outcrop photographs. Individual chapters discuss the historical usage of sequence stratigraphy in the North Sea Jurassic, sequence stratigraphic concepts and models, application in hydrocarbon field development, definition of stratigraphic traps, well sequence interpretation methodology and controls on sequence development. To complete the volume there are further chapters on North Sea Jurassic lithostratigraphy and its relation to sequence stratigraphy, and descriptions of the biozones used to characterize and correlate the sequences.
