This book was released on 1993 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study focuses on the main depocenter of the Andrew Formation in the Moray Firth Basin, located at the junction of the Central and Viking Grabens, in the central North Sea. The objectives of this report are to (1) define the sequence stratigraphic framework of the Andrew Formation, (2) describe and characterize the depositional systems associated to the Andrew slope to basin system, and (3) interpret the depositional processes that have dominated sediment emplacement. Specific facies association of the Andrew Formation are determined by the nature (point source or linear source) and caliber (volume, grain size, sand:mud) of sediment supply to the slope environment. Genetic interpretation of the Andrew Formation focuses on understanding depositional processes which dominated sediment emplacement. Seven depositional facies have been identified for the Andrew slope and basinal system; turbidite channel-fills, turbidite lobes, mounded turbidite lobes, sheet turbidites, debris flows and slumps, low density turbidites and hemipelagic drapes. Seven depositional processes collectively create the above mentioned Andrew depositional facies; turbidity currents, cohesive mud flows, sandy debris flows, muddy debris flows, slumping, low density turbidity currents and suspension settling. The Andrew Formation consists of upper and lower depositional units identified on seismic by bounding downlap terminations and on well logs by high-gamma marker beds. The lower Andrew displays three distinct sand-rich lobes, delineated by isopach and sand percent maps and log motif characteristics. Proximal, mounded, sand-rich units disperse into unchannelized sheet turbidites in the basin plain areas. The upper Andrew downlaps the lower unit, and a single, linear sediment source was centered in the Witch Ground Graben. The sediment dispersal pattern and internal facies character suggest the upper unit is a proximal slope-apron downlapping and filling inter-lobe bathymetric lows of the underlying unit. The lower Andrew is interpreted to be a structurally focused, sand-rich lobe complex, without associated incised canyons. The Andrew system evolved as the delta platform expanded onto the proximal fan, resulting in a linear sediment source spilling over the slope as a fringing slope-apron. The Andrew depositional system in the slope and basin environment is characterized by a high degree of facies disorganization composed of a wide array of gravity-flow deposits.

This book was released on 2012-12-06 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 38 (thesis year 1993) a total of 13,787 thesis titles from 22 Canadian and 164 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 38 reports theses submitted in 1993, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.
Download or read book Terrigenous Clastic Depositional Systems written by William E. Galloway and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonrenewable energy resources, comprising fossil fuels and uranium, are not ran domly distributed within the Earth's crust. They formed in response to a complex array of geologic controls, notably the genesis of the sedimentary rocks that host most commercial energy resources. It is this genetic relationship between economic re sources and environment that forms the basis for this book. Our grouping of petro leum, coal, uranium, and ground water may appear to be incongruous or artificial. But our basic premise is that these ostensibly disparate resources share common genetic attributes and that the sedimentological principles governing their natural distributions and influencing their recovery are fundamentally similar. Our combined careers have focused on these four resources, and our experiences in projects worldwide reveal that certain recurring geologic factors are important in controlling the distribution of com mercial accumulations and subsurface fluid flow. These critical factors include the shape and stability of the receiving basin, the major depositional elements and their internal detail, and the modifications during burial that are brought about in these sediments by pressure, circulating fluids, heating, and chemical reaction. Since the first edition of this book in 1983, there has been a quantum leap in the volume of literature devoted to genetic stratigraphy and refinement of sedimentologi cal principles and a commensurate increase in the application of these concepts to resource exploration and development.
Download or read book Eocene Sequence Stratigraphy of the North Sea Basin written by Benjamin John Sloan and published by . This book was released on 1995 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eocene elastic sediments of the central and northern North Sea comprise five stratigraphic sequences. Oldest is the sand-dominated, basin-centered Frigg sequence, which includes submarine fan and apron deposits on the Beryl Terrace and in the Central and Viking Grabens. Middle Eocene Lower and Upper Hordaland sequences are mixed mud and sand units which prograded from the East Shetland Platform and Moray Firth and include discrete slope aprons and basin-center fans. The thin, regressive sand-prone Belton sequence marks the top of the Eocene in most of the basin, except on the eastern margin of the Shetland Platform, where the foreshelf pro grading prism of Thet sequence sandstones and siltstones was deposited. Foraminiferal biofacies analysis of a well on the Beryl Terrace indicates that four or the five sequence boundaries coincide with significant changes in the benthic and planktic foraminiferal assemblages. Cluster analysis confirms the distinct biofacies characterizing each sequence, an impoverished coarsely agglutinated fauna with radiolaria in the Frigg sequence, normal abundances or coarsely agglutinated forms in the Hordaland units, and "Velasco"-type deep-water calcareous benthics in the Upper Eocene, including planktic foraminifera in the Belton. Paleoenvironmental analysis or these biofacies shows an overall Eocene shallowing from lower slope to outer shelf. Subsidence analysis using the derived water depths indicates that the Eocene was part or a major phase of subsidence which began in the Late Paleocene and abated by Oligocene time. Overall, the Eocene constitutes a tectonosequence, or stratigraphic sequence attributable to tectonic influences. Eocene circum-North Sea tectonics include Atlantic domain seafloor-spreading to the north and west and the encroaching Alpine compression from the south. The base Eocene, top Frigg, and top Eocene all correlate with changes in seafloor spreading thought to have contributed, through intraplate stresses, to the stress regime and differential topography of the source area and basin. Latest Eocene eustatic lowering, climatic cooling, and Arctic water circulation are thought to have influenced the Thet sequence.
Download or read book The Geology of Stratigraphic Sequences written by Andrew D. Miall and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sequence stratigraphy represents a new paradigm in geology. The principal hypothesis is that stratigraphie successions may be subdivided into discrete sequences bounded by widespread unconformities. There are two parts to this hypothesis. First, it suggests that the driving forces which generate sequences and their bounding unconformities also generate predietable three-dimensional stratigraphies. In re cent years stratigraphie research guided by sequence models has brought about fundamental im provements in our understanding of stratigraphie processes and the controls of basin architecture. Sequence models have provided a powerful framework for mapping and numerieal modeling, enabling the science of stratigraphy to advance with rapid strides. This research has demonstrated the importance of a wide range of processes for the generation of cyclie sequences, including eustasy, tectonics, and orbital forcing of climate change. The main objective of this book is to document the sequence record and to discuss our current state of knowledge about sequence-generating processes.

Download or read book Tertiary Deep Marine Reservoirs of the North Sea Region written by T. McKie and published by Geological Society of London. This book was released on 2015-11-02 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discovery of the Arbroath, Montrose and Forties fields initiated intensive exploration of the Tertiary deep-marine play in the North Sea region. Subsequent discoveries demonstrated the success of this play and the geological diversity of the depositional systems. The play is now mature and in many areas the remaining exploration potential is likely to be dominated by small, subtle traps with a major component of stratigraphic trapping. Economically marginal discoveries need an in-depth understanding of subsurface uncertainty to mitigate risk with limited appraisal wells. Mature fields require detailed geological understanding in the search for the remaining oil. This volume focuses on the regional depositional setting of these deep-marine systems, providing a stratigraphic and palaeogeographical context for exploration, and development case histories that outline the challenges of producing from these reservoirs. The fields are arranged around the production life cycle, describing the changing needs of geological models as the flow of static and dynamic data refines geological understanding and defines the nature of new opportunities as fields mature.

Download or read book Seismic Geomorphology written by R. J. Davies and published by Geological Society of London. This book was released on 2007 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are poised to embark on a new era of discovery in the study of geomorphology. The discipline has a long and illustrious history, but in recent years an entirely new way of studying landscapes and seascapes has been developed. It involves the use of 3D seismic data. Just as CAT scans allow medical staff to view our anatomy in 3D, seismic data now allows Earth scientists to do what the early geomorphologists could only dream of - view tens and hundreds of square kilometres of the Earth's subsurface in 3D and therefore see for the first time how landscapes have evolved through time. This volume demonstrates how Earth scientists are starting to use this relatively new tool to study the dynamic evolution of a range of sedimentary environments.

Available in PDF, EPUB and Kindle. Book excerpt: Geological Society Memoir 52 records the extraordinary 50+ year journey that has led to the development of some 458 oil and gas fields on the UKCS. It contains papers on almost 150 onshore and offshore fields in all of the UK’s main petroliferous basins. These papers range from look-backs on some of the first-developed gas fields in the Southern North Sea, to papers on fields that have only just been brought into production or may still remain undeveloped, and includes two candidate CO2 sequestration projects. These papers are intended to provide a consistent summary of the exploration, appraisal, development and production history of each field, leading to the current subsurface understanding which is described in greater detail. As such the Memoir will be an enduring reference source for those exploring for, developing, producing hydrocarbons and sequestering CO2 on the UKCS in the coming decades. It encapsulates the petroleum industry’s deep subsurface knowledge accrued over more than 50 years of exploration and production.
Download or read book Key Issues in Petroleum Geology written by F. John Gregory and published by Geological Society of London. This book was released on 2007 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a compilation of 17 seminal papers, taken from various Geological Society Special Publications and the Journal of the Geological Society, on the use and application of stratigraphy in petroleum geology over the last 20 years. The volume focuses on case studies in fundamental stratigraphy, applied and integrated stratigraphy and alternative methods of stratigraphy. The book is introduced with an original scientific and historical review of the subject: all papers are set in context with both the benefits of the techniques and some of the short-comings highlighted. By compiling these papers, commercial stratigraphers John Gregory, Philip Copestake and Julian Pearce have created a volume intended for a wide readership. However, it is of particular relevance for the training of undergraduate students studying courses on petroleum geology, basin development and sequence stratigraphy as well as for all postgraduate students working in petroleum-related scientific fields. It is also intended as a volume of general use for geoscientists entering the petroleum industry, as well as current workers requiring an overview.
