Available in PDF, EPUB and Kindle. Book excerpt: Diagenesis affects all sediments after their deposition andincludes a fundamental suite of physical, chemical and biologicalprocesses that control the texture, mineralogy and fluid-flowproperties of sedimentary rocks. Understanding the processes andproducts of diagenesis is thus a critical component in the analysisof the evolution of sedimentary basins, and has practicalimplications for subsurface porosity destruction, preservation andgeneration. This in turn is of great relevance to the petroleum andwater industries, as well as to the location and nature of someeconomic mineral deposits. Combines key papers in sandstone diagenesis published inSedimentology over the last 30 years. Records the development of diagenesis from the description ofgrain shapes through provenance, petrography and analyticalgeochemistry to predictive models of diagenetic process. Provides definitions and explanations of the terms and conceptsused in diagenesis.

Download or read book Clay Mineral Cements in Sandstones written by Richard Worden and published by John Wiley & Sons. This book was released on 2009-03-05 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clay minerals are one of the most important groups of minerals thatdestroy permeability in sandstones. However, they also react withdrilling and completion fluids and induce fines migration duringhydrocarbon production. They are a very complex family of mineralsthat are routinely intergrown with each other, contain a wide rangeof solid solutions and form by a variety of processes under a widerange temperatures and rock and fluid compositions. In this volume, clay minerals in sandstones are reviewed interms of their mineralogy and general occurrence, their stable andradiogenic isotope geochemistry, XRD quantification, their effectson the petrophysical properties of sandstones and theirrelationships to sequence stratigraphy and palaeoclimate. Thecontrols on various clay minerals are addressed and a variety ofgeochemical issues, including the importance of mass flux, links tocarbonate mineral diagenesis and linked clay mineral diagenesis ininterbedded mudstone-sandstone are explored. A number of casestudies are included for kaolin, illite and chlorite cements, andthe occurrence of smectite in sandstone is reviewed. Experimentalrate data for clay cements in sandstones are reviewed and there aretwo model-based case studies that address the rates of growth ofkaolinite and illite. The readership of this volume will include sedimentologists andpetrographers who deal with the occurrence, spatial and temporaldistribution patterns and importance of clay mineral cements insandstones, geochemists involved in unraveling the factors thatcontrol clay mineral cement formation in sandstones and petroleumgeoscientists involved in predicting clay mineral distribution insandstones. The book will also be of interest to geologistsinvolved in palaeoclimate studies basin analysis. Latest geochemical data on clays in sandstones Provides important information for geologists involved inbasin analysis, sandstone petrology and petroleum geology If you are a member of the International Association ofSedimentologists (IAS), for purchasing details, please see:http://www.iasnet.org/publications/details.asp?code=SP34

Download or read book Sediment Diagenesis written by A. Parker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: The topic of sediment diagenesis is of fundamental importance to industry in the evaluation of hydrocarbon and water reservoir rocks. Detailed knowledge of the diagenetic textures, fabrics, and minerals, and a prediction of the regional diagenetic response, partly controls hydrocarbon recovery programmes. In other words, knowledge of the diagenesis can aid (or even control) conservation policy. Similarly, facies and diagenetic trends w.ithin basins can influence exploration policy. This volume incorporates the majority of the principal contributions given to the NATO Advanced Study Institute held in the University of Reading, U.K., from July 12th-25th, 1981, at which the major themes of carbonate and terrigenous clastic sediments were treated sequentially from deposition to deep burial. Eighty selected scientists from twelve NATO and three other countries participated in the Institute. The keynote addresses which acted as the touchstones for discussion are presented here in the expectation that they will stimulate a still wider audience. We gratefully acknowledge the award of a grant from the Scientific Affairs Division of NATO to run the Institute, and also the cooperation of the University of Reading. Mrs. D. M. Powell helped in many ways with the organisation, and also retyped the entire manuscript of this book. A. Parker B. lv.

Book Synopsis Reservoir Quality of Clastic and Carbonate Rocks by : P.J. Armitage
Download or read book Reservoir Quality of Clastic and Carbonate Rocks written by P.J. Armitage and published by Geological Society of London. This book was released on 2018-06-18 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reservoir quality is studied using a wide range of similar techniques in both sandstones and carbonates. Sandstone and carbonate reservoir quality both benefit from the study of modern analogues and experiments, but modelling approaches are currently quite different for these two types of reservoirs. There are many common controls on sandstone and carbonate reservoir quality, but also distinct differences due primarily to mineralogy. Numerous controversies remain including the question of oil inhibition, the key control on pressure solution and geochemical flux of material to or from reservoirs. This collection of papers contains case-study-based examples of sandstone and carbonate reservoir quality prediction as well as modern analogue, outcrop analogue, modelling and advanced analytical approaches.
Book Synopsis Does Oil Emplacement Stop Diagenesis and Quartz Cementation in Deeply Buried Sandstone Reservoirs by : Mohammed Bukar
Download or read book Does Oil Emplacement Stop Diagenesis and Quartz Cementation in Deeply Buried Sandstone Reservoirs written by Mohammed Bukar and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Reservoir quality relates to the presence of porosity and the connectivity of the pores of the reservoir rock which controls permeability. Deeply buried sandstones in sedimentary basins lose their reservoir quality due to compaction and cementation. Quartz cement is the most volumetrically important porosity occluding cement in sandstones buried to depths greater than about 3000m. Precipitation of quartz cement requires a source of silica, transportation of the silica in solution from source to the point of precipitation and clean grain surfaces to grow on. For these processes to take place water is required to dissolve the mineral grains that provide the source of silica, to provide aqueous fluid pathway from the site of mineral dissolution to the site of precipitation and water is required at the site of mineral precipitation to enable mineral growth. In oil or gas fields, displacing the aqueous pore fluid by petroleum disrupts the pathway between the reactants and points of precipitation. If the oil saturation becomes high; (i) the residual (irreducible) water becomes isolated within a continuous hydrocarbon phase or (ii) the aqueous pathway becomes tortuous and diffusion becomes slow or (iii) grain surfaces become coated by oil if the sandstone is oil wet. However, over the years a controversy has developed as to whether oil emplacement into reservoir stops quartz cementation and preserves porosity at depth. The research presented in this thesis used core samples, wireline logs and well reports collected from the oil and water legs and the transition zone of Upper Jurassic marine sandstones of the Ula and Tambar fields from the Norwegian North Sea. They were studied using a range of techniques: core analysis, core logging, downhole wireline analysis, optical microscopy, scanning electron microscope (SEM), cathodoluminescence (CL), X-ray diffraction (XRD), fluid inclusion UV-petrology and thermometry. The distributions of all potential controls on porosity and permeability have been quantified so that it has been possible to assess the influence of all possible controls on quartz cement as well as fluid type. Thus the roles of depositional facies, grain size, sorting, chlorite coats and microcrystalline quartz coats have all been assessed. The main diagenetic cements in both Ula and Tambar fields are quartz overgrowths, grain coating microcrystalline quartz, K-feldspar cement, illite, dolomite and minor amounts of calcite and chlorite. Fluid inclusion evidence shows that quartz cementation was probably a continuous process and is still taking place in both fields. Quartz cementation occurred in the presence of some oil, as shown by the presence of oil inclusions within quartz cement in both Ula and Tambar. However, there are far fewer oil inclusions in quartz cement in Tambar than Ula suggesting that oil emplacement occurred later in Tambar than Ula. There is less quartz cement in the coarser grained sandstones in the oil legs than the water legs of Ula and Tambar suggesting that quartz cementation has been inhibited, in these facies, by the addition of oil. Finer-grained facies in both fields have more grain-coating microcrystalline quartz that has effectively inhibited quartz cementation in both oil and water legs. Stable isotope data show that the carbonate cements in the oil leg grew at relatively lower temperatures than those in the water legs. Precipitation temperature for carbonate cement in the oil leg stopped at the time of oil emplacement but carbonate cements in the water leg carried on growing or recrystallising at higher temperatures and show progressive input of source-rock derived CO2 (as the carbon isotopes get progressively lighter) in both Ula and Tambar fields. Reservoir quality in the Ula field is primarily controlled by a combination of depositional facies, mechanical compaction and early oil emplacement and locally by facies-controlled microcrystalline quartz. In the Tambar field early-formed grain-coating microcrystalline quartz mainly controls the reservoir quality and effects of oil emplacement are not as significant as in Ula due to the later oil charge. The results of this work have academic and economic significance. Understanding the controls on reservoir quality and the effect of oil emplacement on quartz cementation may be used (1) as analogues in other basins of known petroleum charge history, (2) to improve appropriate reserve calculation and well planning during the appraisal stage and (3) to assist in reliable prediction of aquifer performance during production, and lead to proper decision on number and positions of injection wells during the later life of the field.

Book excerpt: This is a discount Black and white version. Some images may be unclear, please see BCCampus website for the digital version.This book was born out of a 2014 meeting of earth science educators representing most of the universities and colleges in British Columbia, and nurtured by a widely shared frustration that many students are not thriving in courses because textbooks have become too expensive for them to buy. But the real inspiration comes from a fascination for the spectacular geology of western Canada and the many decades that the author spent exploring this region along with colleagues, students, family, and friends. My goal has been to provide an accessible and comprehensive guide to the important topics of geology, richly illustrated with examples from western Canada. Although this text is intended to complement a typical first-year course in physical geology, its contents could be applied to numerous other related courses.

Available in PDF, EPUB and Kindle. Book excerpt: Carbonate cements are very common and abundant in clastic sequences. They profoundly influence the quality of hydrocarbon reservoirs and supply important information on palaeoenvironments and the chemical composition and flow patterns of fluids in sedimentary basins. Despite this importance, their distribution patterns in time and space and their geochemical evolution are not yet deeply explored and elucidated. This Special Publication contains 21 review papers and case studies on carbonate cementation in clastic sequences written by invited specialists on the subject. These papers present a wide and deep coverage that enhance our knowledge about carbonate cementation in various clastic depositional environments, tectonic settings and burial histories. The book will be of special interest to researchers, petroleum geologists and teachers and students at the postgraduate level.

Book Synopsis Impact of grain coats on quartz overgrowth and Reservoir properties by : Busch, Benjamin
Download or read book Impact of grain coats on quartz overgrowth and Reservoir properties written by Busch, Benjamin and published by KIT Scientific Publishing. This book was released on 2017-07-28 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Syntaxial overgrowth cementation, and thereby reservoir quality, can be affected by grain coating phases inhibiting nucleation. Reaction kinetics provide a means to model the development of cement phases over time. Additional algorithms constraining compaction behavior, porosity, and permeability development are used to model reservoir quality. Sub-vertical deformation bands can compartmentalize reservoirs by impacting bed-parallel permeability and preserve geochemical alterations.
Download or read book The Ordos Basin written by Renchao Yang and published by Elsevier. This book was released on 2021-11-30 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ordos Basin: Sedimentological Research for Hydrocarbons Exploration provides an overview of sedimentological approaches used in the lacustrine Ordos Basin (but also applicable in other marine and lacustrine basins) to make hydrocarbon exploration more efficient. Oil exploration is becoming increasingly focused on tight sandstone reservoirs and shales. The development of these reservoirs, particularly regarding the sedimentary processes and the resulting sediments, are still poorly understood. Exploration and exploitation of such reservoirs requires new insights into the lateral and vertical facies changes, and as already indicated above, the knowledge surrounding facies and how they change in deep-water environments is still relatively unclear. Covers several geological aspects so the reader may well understand the context of the various chapters Explores and explains the important relationship between sedimentology and hydrocarbon explorations Highlights the significance of sedimentological aspects (facies, porosity, etc.) for basin analysis and the development of energy resources

Book Synopsis Rainbow of Rocks by : Marjorie A. Chan
Download or read book Rainbow of Rocks written by Marjorie A. Chan and published by Utah Geological Survey. This book was released on 2002-10 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sunrise illuminates Colorado Plateau’s canyon country. In the early morning light, cliffs radiate a rich red glow, and a sculptured panorama of sandstone is revealed in a rich palette of crimson, vermilion, orange, salmon, peach, pink, gold, yellow, and white. Nearby are black, spherical rock marbles (iron concretions) collecting in small depressions, like puddles of ball bearings. These natural spherical balls have been called various names such as iron nodules, iron sandstone balls, or moki marbles. However, we use the name “iron concretion” to describe both the composition (iron oxide that is the dark mineral which cements the sandstone grains) and the formed shape (concretion). What paints the sandstone such rich colors? Why is red a dominant color? Where do the black marbles come from? How did the black marbles form? Is there a relationship between sandstone colors and the marbles? This booklet explores the answers to these questions and poses other questions yet unanswered.
