    Beschreibung / Inhaltsverzeichnis: Laminated coating systemsAfter the introductory discussion of the selection of suitable natural and synthetic textiles and of coating agents for the preparation of laminated coating systems (coats with fabric insertions), an illustrated survey of some magnitude is given of coating techniques for laminated coating system on metal surfaces. It is shown in detail that such coatings are much superior to normal coating in regard to freedom from defects, mechanical proporties, and protection against various aggressive liquids (mineral acids, solvents).
    Notizen: Einleitenden Richtlinien für die Auswahl geeigneter natürlicher und synthetischer Textilien sowie Anstrichmittel zum Aufbau laminierter Anstrichsysteme (Anstriche mit Gewebeeinlage) folgt ein ausführlicher Abriß über die Technologie des Aufbringens laminierter Anstriche auf Metalloberflächen in Wort und Bild. Es wird in allen Einzelheiten gezeigt, daszlig; Fehlerfreiheit, mechanische Eigenschaften und der Schutzwert des Systems gegen verschiedene aggressive Flüssigkeiten (Mineralsäuren, Lösungsmittel) ungleich höher sind als bei einfachen Anstrichen.

    Notizen: In Drehscheiben-Kolonnen (Rotating disc-Kolonnen) von 64 bis 2180 mm Dmr. wurden die axiale Vermischung und die Rückvermischung in der kontinuierlichen Phase sowie die axiale Vermischung in der dispergierten Phase untersucht. Es konnte eine befriedigende Korrelation zwischen axialer Vermischung und der Rückvermischung in der kontinuierlichen Phase einerseits und den geometrischen Variablen und betrieblich veränderlichen Größen solcher Kolonnen andererseits ermittelt werden.

    Quantitative sequence stratigraphy (2018)
    American Association of Petroleum Geologists (AAPG)
    Details
    Publikationsdatum: 2018
    Beschreibung: 〈span〉〈div〉ABSTRACT〈/div〉Sequence stratigraphy based on wire-line logs, cores, and outcrops is entering its fourth decade of mainstream usage in industry and academia. The technique has proved to be an invaluable tool for improving stratigraphic analyses in both clastic and carbonate settings. Here we present a simple quantitative technique to support sequence stratigraphic interpretations in clastic shallow marine systems. The technique uses two pieces of data that are readily available from every subsurface field or outcrop study: (1) parasequence thickness (T) and (2) parasequence sandstone fraction (SF). The key assumptions are that parasequence thickness can be used as a proxy for accommodation at the time of deposition and parasequence sandstone fraction can be used as a proxy for sediment supply. This means that quantitative proxies for rates of accommodation development and sediment supply can be acquired from wire-line logs, cores, and outcrop data. Vertical trends in parasequence thickness divided by sandstone fraction (T/SF) approximate trends expected in systems tracts for changes in ratios of rate of accommodation development to rate of sediment supply. The technique, termed “TSF analysis,” can also be applied at lower-order sequence and composite sequence scales. It provides a quantitative and objective methodology for determining rank and order of sequence stratigraphic surfaces and units. Absolute T/SF values can be used to determine shoreline, stacked shoreline, and shelf-margin trajectories. Four case studies are presented, which demonstrate the robustness of the technique across a range of different data sets. Implications and potential future applications of TSF analyses are discussed.〈/span〉

    Heat flow and thermal conductivity measurements in the northeastern Pennsylvania Appalachian Basin depocenter (2018)
    American Association of Petroleum Geologists (AAPG)
    Details
    Publikationsdatum: 2018
    Beschreibung: 〈span〉〈div〉ABSTRACT〈/div〉The northern Appalachian Basin depocenter of Pennsylvania represents one of the most economically important hydrocarbon-producing areas in the United States, yet the thermal conditions that promoted hydrocarbon formation within the basin are only marginally constrained. The prolific coal, oil, and natural gas fields of Pennsylvania are the direct result of thermal maturation of once deeply buried organic-rich sediment. Understanding how, why, and where thermal maturation occurred in the Appalachian Basin requires high-quality heat flow and thermal conductivity measurements, as well as paleotemperature estimates and basin modeling. To improve the understanding of heat flow, we present, to our knowledge, the first direct measurements of (1) thermal conductivity on Devonian core samples and (2) equilibrium temperature versus depth logs for the northern Appalachian Basin depocenter. Results from three well sites demonstrate that heat flow is conductive and nearly uniform, averaging 34 ± 2.5 mW/m〈sup〉2〈/sup〉, with an average thermal gradient of 29 ± 4°C/km. The new heat-flow measurements are significantly lower (30%–50% less) than previously published estimates that used nonequilibrium bottomhole temperature values and empirically derived thermal conductivity estimates. Our analysis indicates that previous studies correctly estimated the regional thermal gradient using bottomhole temperatures but overestimated heat flow in this region by as much as 50% because of inaccurate extrapolation of thermal conductivity. The results highlight the importance of directly measuring thermal conductivity to accurately quantify heat flow in deep sedimentary basins. Ultimately, additional paleotemperature data are necessary to improve our understanding of Appalachian Basin thermal evolution.〈/span〉

    Dip-related changes in stratigraphic architecture and associated sedimentological and geochemical variability in the Upper Cretaceous Eagle Ford Group in south Texas (2018)
    American Association of Petroleum Geologists (AAPG)
    Details
    Publikationsdatum: 2018
    Beschreibung: 〈span〉〈div〉ABSTRACT〈/div〉A detailed, rock-based investigation of three Upper Cretaceous Eagle Ford Group cores situated behind, at, and downdip of the Lower Cretaceous Stuart City paleoreef-shelf margin in south Texas was conducted to understand stratigraphic, sedimentological, and geochemical relationships across this buried shelf margin. An understanding of how the Eagle Ford Group lithofacies vary across the paleoreef-shelf margin is currently lacking. We therefore examined a dip section of three cores across the antecedent shelf margin and delineated seven Eagle Ford lithofacies: (1) massive argillaceous mudstone, (2) massive to laminated foraminiferal lime wackestone, (3) radiolarian and foraminiferal dolomitic to lime packstone, (4) massive to bioturbated skeletal lime wackestone, (5) laminated foraminiferal lime packstone, (6) laminated inoceramid and foraminiferal lime grainstone, and (7) massive to bioturbated claystone. A basinward decrease in calcite from 60% to 48% is accompanied by an increase in clay minerals from 12% to 20%. The low-relief raised rim of the older, buried Stuart City paleoshelf margin may have acted as a barrier, dividing the Eagle Ford Group into two sedimentological systems: (1) a restricted drowned shelf to the north, and (2) an open-marine basinal setting to the south. The lower to upper Cenomanian Eagle Ford strata on the drowned shelf are cyclic and enriched in molybdenum, suggesting anoxic to euxinic water masses. The anoxic, open-marine, basinward strata are less cyclical and have a lower molybdenum (compared with the drowned shelf) content. Ash beds and gravity-flow deposits are rare south of the margin. A depositional model was constructed of the lower and upper Eagle Ford formations.〈/span〉

    An uncertainty approach to estimate recoverable reserves from the Bakken petroleum system in the North Dakota part of the Williston Basin (2019)
    American Association of Petroleum Geologists (AAPG)
    Details
    Publikationsdatum: 2019
    Beschreibung: 〈span〉〈div〉ABSTRACT〈/div〉Instead of using discrete values for properties that influence the volumetric calculation for recoverable reserves from the Middle Bakken, Pronghorn, and Three Forks reservoir rocks in the Williston Basin in North Dakota, an uncertainty-based assessment method was used. Various estimates have been published in the past that attempt to quantify recoverable reserves from the Bakken petroleum system. The Bakken–Three Forks trend is regarded as an unconventional tight oil play typical of a continuous-type basin-centered accumulation. However, production data reveal that areas are unequal and that certain regions stand out as sweet spots whereas others exhibit fairly high water cuts. This paper is based on 28 well models, which have been porosity-calibrated and adjusted for the prevalent thermal regime. The area of interest was delineated by geological parameters such as shale maturity and reservoir rock presence as well as existing production data. The purpose of this study is to use an uncertainty assessment method based on hundreds of basin model simulations that sample ranges of probable input parameters to quantify the recoverable reserves from the Bakken petroleum system in North Dakota. The results are displayed in reverse cumulative probability plots, tornado sensitivity charts, as well as in maps of the 10% chance, 50% chance (P50), 90% chance values. This means that there is an X% chance of success or an X probablity of realizing a certain amount of hydrocarbon. The P50 results of the uncertainty assessment indicate that approximately 4 billion bbl of oil and 3.6 tcf (102 billion m〈sup〉3〈/sup〉) of gas are recoverable from the Middle Bakken, Pronghorn, and Three Forks reservoir rocks in North Dakota. The Bakken–Three Forks trend appears to be an overcharged petroleum system, where the available pore space in reservoir rocks is the limiting factor for each accumulation.〈/span〉
