This book was released on 2010-09-02 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Niger Delta is a prolific oil province within the West African subcontinent. Exploration activities have been concentrated in the onshore part of this basin, but as the delta becomes better understood, exploration influences are gradually being shifted to the offshore. Although the geology, tectonics and evolution of the Eocene-Pliocene sequence of the Niger Delta are fairly well known, these are expected to increase as new analytical tools and concepts evolve. This work was an integrated structural, seismic facies and stratigraphic study conducted in the Fabi Field, onshore western Niger Delta, and targeted at improving the present understanding of the structural development, sequence stratigraphic history, paleo-depositional environments and hydrocarbon reservoir potential of the field. Five wireline logs, biostratigraphic data, 3-D seismic section, check shot data and core data were analysed and utilized in this study. Well logs were used to determine the different lithologies, system tracts, stacking patterns and reservoir potentials of the field. Sequence stratigraphy and seismic facies were used to identify the reflection packages in order to determine the environment of deposition. Structural and horizon mapping results were used to generate time and depth structural map with the aid of a derived function calculated from the check shot data. The base of these sequences consists of massive and monotonous marine bioturbated shales, which grade into inter-bedding shallow marine fluvial sands with parallel-cross bedding laminations, silt and clays, while the upper part is a massive marine sandstone section. The gross reservoir thickness ranges from 150ft-700ft with net thickness of 20ft-175ft. Sequence stratigraphic analysis revealed that the succession consists of two sequence boundaries, dated 10.35Ma and 10.6Ma and two maximum flooding surfaces, dated 9.5Ma and 10.4Ma. The high percentage of the reflections with low to moderate amplitude/continuity of the parallel/divergent configuration is identified as a feature of delta platform facies, while the sigmoidal-hummoky reflections indicate a slope facies. The system tracts from the log are the trangressive and highstand system tracts, while growth faults(F1), antithetic faults(F3,F4) and synthetic faults (F2,F5,F6,F7) are the identified structures which are typical of the Niger Delta reservoir sandstone. Depositional setting of the Middle-Upper Miocene strata were influenced by fluvial, tidal and marine systems. The up dip areas on the depth structure maps with closure signify possible anticlinal structures where hydrocarbons could be entrapped. These could serve as possible appraisal locations where wells could be sited to optimize the development of the reservoir sands within the field using the structural model generated.

This book was released on 2018-08-13 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Project Report from the year 2017 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 5.0, , course: Geology, language: English, abstract: This study is aimed at determining the geology and depositional environment of Ameki Formation in Bende and environs through field descriptions, textural analysis and Palynological analysis. The mapped area which covers an area of about 180sq km and is located around Bende, southeastern Nigeria. The study area is bounded by Longitude 07° 30` E and 07° 43` E and Latitudes 05° 30` N and 05° 39` N. The area is underlain by Paleocene Imo Formation and Eocene Ameki Formation. The Ameki Formation is a clastic unit that overlies the marine Imo Formation and it consists of sandstone, shales, limestone, ironstone and siltstones. The Eocene Ameki Formation in southeastern Nigeria consists, in its type locality of five lithologic units; calcareous sandstone, pebbly bioturbated sandstone, grey-dark shale, argillaceous sandstone and pebbly sandstone. The floral, faunal and lithologic studies of the Eocene Ameki Formation suggest sediments deposited in a continuity from nearshore (barrier-ridge estuarine complex) to shallow marine (intertidal and subtidal zones) environment. The sieve analysis unveils that the univariate parameters indicate a fluvially intercepted shallow marine environment with tidal crosscuts, the log probability plots suggest tidal environment while from the bivariate plots; a beach influenced fluvial environment is interpreted. The pebble morphological analysis showed that the pebble clast have being shaped by beach action as revealed by the bivariate scatter plots of pebble form indices while in multivariate aspect a fluvially dissected shallow marine environment with tidal interferences was interpreted. The palynological analysis indicated a marginal marine source for the sediment and that the formation (Ameki) is Eocene in age.

Book excerpt: Bachelor Thesis from the year 2022 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 4.06, University of Nigeria, course: Geology, language: English, abstract: The study covers the areas around Ihe, a town in Awgu southeastern Nigeria. It lies within the Anambra Basin and is underlain by the Nkporo Group and Mamu Formation. Geologic field mapping involved outcrop description and lithofacies analysis. Laboratory studies include sieve analysis, paleocurrent analysis and pebble morphometry. These studies were carried out in order to interpret the paleodepositional environment of the rocks mapped. The lithofacies mapped consist of six lithofacies which include; Cross bedded sandstone facies, Shale facies, Structureless (massive) sandstone facies, Parallel laminated sandstone facies, bioturbated sandstone facies, and Ironstone facies. These lithofacies represents three facies association; FA1 - marine deposits, FA2 - shoreface deposits and FA3 - mouth bar deposits. This implies that the sediments were deposited within the marginal marine, shallow marine and marine environment respectively. The results from sieve analysis indicates that the sandstones are medium - coarse grained and poorly moderately sorted. Derivations from multivariate and bivariate sieve results depicts a fluvial setting. The pebble morphometry result also implies a fluvial setting. The paleocurrent analysis showed a unimodal pattern with provenance in the NW, possibly the western and northcentral basement complex area. A mean vector azimuth of 79.6o and a variance of 758.635o signified low sinuosity fluvial setting and southeasterly paleoflow direction. The integration of the results gotten from the various analysis interprets the paleodepositional environment of Ihe and environs to be a fluvial dominated marginal marine environment.

Book excerpt: Investigations about porosity in petroleum reservoir rocks are discussed by Schmoker and Gautier. Pollastro discusses the uses of clay minerals as exploration tools that help to elucidate basin, source-rock, and reservoir history. The status of fission-track analysis, which is useful for determining the thermal and depositional history of deeply buried sedimentary rocks, is outlined by Naeser. The various ways workers have attempted to determine accurate ancient and present-day subsurface temperatures are summarized with numerous references by Barker. Clayton covers three topics: (1) the role of kinetic modeling in petroleum exploration, (2) biological markers as an indicator of depositional environment of source rocks and composition of crude oils, and (3) geochemistry of sulfur in source rocks and petroleum. Anders and Hite evaluate the current status of evaporite deposits as a source for crude oil.

This book was released on 2013-04-17 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended as a practical handbook for those engaged in the task of analyzing the paleogeographic evolution of ancient sedimentary basins. The science of stratigraphy and sedimentology is central to such endeavors, but although several excellent textbooks on sedimentology have appeared in recent years little has been written about modern stratigraphic methods. Sedimentology textbooks tend to take a theoretical approach, building from physical and chemical theory and studies of mod ern environments. It is commonly difficult to apply this information to practical problems in ancient rocks, and very little guidance is given on methods of observation, mapping and interpretation. In this book theory is downplayed and the emphasis is on what a geologist can actually see in outcrops, well records, and cores, and what can be ob tained using geophysical techniques. A new approach is taken to stratigraphy, which attempts to explain the genesis of lithostratigraphic units and to de-emphasize the importance of formal description and nam ing. There are also sections explaining principles of facies analysis, basin mapping methods, depositional systems, and the study of basin thermal history, so important to the genesis of fuels and minerals. Lastly, an at tempt is made to tie everything together by considering basins in the con text of plate tectonics and eustatic sea level changes.

This book was released on 2013-03-09 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: The user This manual is designed for the use of geo-scientists with an interest and need in developing palaeobiological materials as a potential source of data. To meet this objective practical procedures have been formatted for use by both professional and semi professional students with an initial understanding of palaeo biological research aims as a primary source of scientific data. I have attempted to provide an explanation and understanding of practical procedures which may be required by students undertaking palaeobiological projects as part of a degree course. The layout of this manual should be particularly beneficial in the instruction and training of geotechnologists and museum preparators. Graduate students and scientists requiring an outline of a preparation procedure will also be able to use the manual as a reference from which to assess the suitability of a procedure. This manual is also intended for use by the "committed amateur". Many of the techniques described in this manual have been devised by non-palaeontologists, and developed from methods used in archaeology, zoology and botany, as well as other areas of geology. A considerable number of the methods can be undertaken by the amateur, and in the case of many of the field procedures, should be used. This will ensure that specimens and samples can be conserved in such a manner as to facilitate any later research, and not invalidate the results of subsequent geochemical analytical techniques which might be employed.

Available in PDF, EPUB and Kindle. Book excerpt: Sedimentary rocks contain the most important archive of environmental change through earth history. They record changing climates, the movement of plates, and the rise and fall of sea-level on timescales of a few thousand to billions of years. This fully revised and updated edition introduces the reader to sedimentology and stratigraphic principles, and provides tools for the interpretation of sediments and sedimentary rocks. The processes of formation, transport and deposition of sediment are considered and then applied to develop conceptual models for the full range of sedimentary environments, from deserts to deep seas and reefs to rivers. Different approaches to using stratigraphic principles to date and correlate strata are also considered, in order to provide a comprehensive introduction to all aspects of sedimentology and stratigraphy. The text and figures are designed to be accessible to anyone completely new to the subject, and all of the illustrative material is provided in an accompanying CD-ROM.

Download or read book Paleocurrents and Basin Analysis written by P. E. Potter and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of paleocurrents, since 1963, is now a very routine part of sedimentology, and more and more such studies are finding use in other fields. Thus it seemed appropriate for us to review post-1963 developments and present them in a compact manner for the interested reader. Instead of rewriting a second edition, which thirteen years later we would organize in a completely dif ferent way, we have brought each chapter up to date with new material up to 1976. A new update supplement has in this edition been inserted after each one of the original chapters. We have stayed close to the original theme of paleocurrents-how to measure them and how to use them to solve geological problems ranging in scale from the hand specimen to the sedimentary basin and beyond. We have used many annotated references and tables to help pre sent this information to the reader. The reader will note that we have cited a few 1962 references - pUblications that appeared too late to be cited in the original 1963 edition. A few times we have also cited a reference which was included in the first edition. These are marked with an asterisk and hence do not appear in the new lists of references. We have been aided by many. In Cincinnati, WANDA OSBORNE and JEAN CARROL did typing and RICHARD SPOHN, the University's geological librarian, was very helpful in obtaining many references to the literature.
