Investigation of Pallet Stacking Pattern on Unit Load Bridging
… of the interlocking of layers and the pallet stacking patterns on pallet bending. This effect is part of a greater encompassing observed behavior known as load bridging, where a redistribution of the stresses on the pallet dependent on the characteristics of the load is generated. The bending …

Facies architecture and mechanical stratigraphy of Mississippian grainy and muddy carbonate sediment gravity-flow deposits: Rancheria Formation, Sacramento Mountains, New Mexico
… the profound influence that bed thickness, stacking patterns, and textural heterogeneity pose on fracture dimensions and propagation trends. Thicker, more homogeneous intervals typically host taller fractures as vertical propagation continues until a substantial mechanical boundary is …

Multi-scale stratigraphic and statistical analysis of allogenic and autogenic controls on fluvial systems
… boundary conditions on fluvial channel belt stacking patterns. Specifically, how the valley confined Dakota Sandstone is inherently different than the unconfined lower Wasatch Formation in regards to clustering, compensational stacking, and connectivity (Chapter 2). Results from this chapter …

Evaluating the impact of deep-water channel architecture on the probability of correct facies classification using 3D synthetic seismic data
… channel deposits reveal that channel element stacking patterns and internal architecture strongly control connectivity. This architecture is critical to understanding hydrocarbon flow and recovery but is unresolvable in exploration-scale seismic-reflection profiles. Forward seismic …

Stratigraphic architecture of a shallow-water delta deposited in a coastal-plain setting: Neslen Formation, Floy Canyon, Utah
… has similar longitudinal lithofacies trends and stacking patterns to modern analog deltas deposited in similar water depths (such as the Okavango and Wax Lake deltas). When compared to a relatively deeper-water delta, such as the delta documented by Matthew Andresen in the Iles Formation, the …

Influence of climate and the expansion of C4 grasses on sequence-scale cyclicity and landscape development during the late Miocene to Pleistocene of West Texas.
… influenced fluvial depositional style. Alluvial stacking-pattern analysis of two drill cores reveals sequence-scale trends in paleosol maturity, cycle thickness, and facies proportions. Stable isotope geochemistry of bulk paleosol samples and pedogenic carbonate suggest C₄ expansion at 7.25 Ma …

Architecture of fluvio-deltaic sandbodies: the Namurian of Co. Clare, Ireland, as an analogue for the Plio-Pleistocene of the Nile Delta
… channel dimensions, internal architectures and stacking patterns. Based on these data, the Tullig Sandstone, a major sandbody within the Central Clare Group, is interpreted to be a low-sinuosity, braided fluvial system that flowed to the north-northeast. This sandbody shows decreasing amounts of …

Establising a high-frequency standard reference sequence stratigraphy, sea-level curve, and biostratigraphy for Morrowan strata of the Lower Absaroka I time slice based upon the Bird Spring Formation, Arrow Canyon, Nevada
… sea-level changes. Outcrop data and facies stacking patterns define 59 fifth-order fundamental cycles. These fundamental cycles stack into ten third-order sequences with an average duration of 320 ka. Changes in both cycle thickness and fundamental cycle type indicate that the second-order …

Characterization of Lower Permian Carbonate Subaqueous Gravity Flows in Crockett County, Texas
… and the lithofacies. Interpretation of stratal stacking patterns and gravity flow transport processes are used to interpret highstands shedding of grainstones, falling stage and lowstands carbonate conglomerate debris, and a transgressive drape of shale ending a full second order sequence that …

Sequence Stratigraphy and Paleoecology of the Late Mississippian Little Stone Gap Member in the Appalachians of West Virginia
… flank and open marine settings. Parasequence stacking patterns are interpreted as resulting from regional fifth-order glacioeustatic sea-level changes consistent with established age constraints for fourth-order sequences. Detrended Correspondence Analysis (DCA) of paleontological bulk samples …

SEDIMENTOLOGY, ICHNOLOGY, AND SEQUENCE STRATIGRAPHY OF THE MIOCENE OFICINA FORMATION, ORINOCO OIL BELT, EASTERN VENEZUELA BASIN
… fossils, depositional environments, stratal stacking patterns and surfaces of sequence stratigraphic significance have been analyzed in the Junín and Boyacá areas. The Oficina Formation is subdivided here into three members: Lower, Middle, and Upper. The Lower Member consists mainly of …

Effects of Sedimentologic and Stratigraphic Heterogeneity on Production in Carbonate Reservoirs: An Integrated Outcrop, Synthetic Geologic Modeling, and Flow Simulation Study
… related to depositional geometry, facies stacking patterns, diagenetic surfaces and bodies, porosity distribution, and permeability distribution. A total of 750 flow simulations of these geologic models provide a means to quantify the impact, relative importance, and risk associated with …

Controls on Stratigraphy and Architecture of Shallow-Water Deltas: Examples from the Early Cretaceous of Central-Eastern Spain
… sediment supply allogenic controls, influencing stacking patterns, internal architecture and overall evolution. This study advances our scientific understanding of these processes but has applied implications for subsurface reservoir architecture models used by the oil and gas industry.

Variations in the architecture of fluvial deposits within a marginal marine setting, Eocene Sobrarbe and Escanilla formations, Spain
… knowledge of how large-scale stratigraphic stacking patterns can be used as a predictor of small- (reservoir) scale characteristics and how subdividing populations on the basis of geological distinctions can have important implications when building reservoir models (Chapter 3). Third, this …

Condensed and Expanded Sections in the Lower Mesaverde Clastic Wedge, Campanian of Wyoming: Evidence for Tectonic Rectification of Sea Level
… casts, the inferred paleo-gradient, sequence of stacking patterns, and the presence of incised valleys and unconformities. The evidence shows that the evolution of these members was coupled closely to eustatic and tectonic changes. At the time of Virgelle deposition, the subsidence rate was too …

Cyclostratigraphy of Late Cambrian cyclic carbonates: An interbasinal field and modelling study, U.S.A.

Previous studies have emphasized the stacking patterns comprising the outer few kilometers of the platform but have given little to no recognition to the breccia prone high-energy shorelines deposits and have not incorporated this distinct facies into depositional models. Comparison of …

The influence of surface - subsurface connectivity on groundwater flow and solute transport in a deltaic aquifer
