Summary: One of S. George Pemberton's significant contributions to ichnology is the identification of burrowed firmgrounds associated with the Glossifungites Ichnofacies as important sequence stratigraphic allogenic surfaces. This study examines an outcrop example from the Turonian Ferron Sandstone in central Utah and finds that high and low abundance monospecific suites of Glossifungites isp. record colonization in channels under low salinity conditions in landward marginal-marine settings. The study also suggests that the trace fossils may have been made by marine-recruited, brackish-water crustaceans or divergent subaqueous insects from known modern tracemakers.

Summary: The study reconstructed the palaeohydrology of Late Cretaceous palaeorivers in central Utah using field measurements and quantitative methods, revealing similarities in river morphologies in space and time, as well as decreasing slopes downstream with a notable increase at the Blackhawk-Castlegate transition. There was no change in unit water discharges at this transition, supporting a tectonic-driven increase in slope rather than a climatically-driven change.

Summary: The study utilizes a 400 km transect of the Cenomanian Mesa Rica Sandstone to map changes in facies, thickness distribution, and fluvial architecture. The formation of incised valleys impacts sequence stratigraphic interpretations, as it evidence sea-level fall. The study challenges the idea of a single, correlatable surface in fluvial realms and highlights erosion and deposition occur simultaneously.

Summary: Shoreface deltaic depositional systems form excellent stratigraphic traps that are developed under adverse sea-level conditions, impacting the quantitative prediction of stratigraphic reservoirs. The thin-bedded reservoirs require specific tuning frequencies for accurate thickness and distribution, with band-limited seismic attributes not being reliable tools for cost-effective stratigraphic plays. Continuous wavelet transforms and thickness modeling have been used to enhance the prediction of reservoir thickness and presence of hydrocarbons along UDS.

Summary: Fluvial-deltaic systems are affected by nonuniform backwater flow, resulting in sediment aggradation and downstream fining. This study combines stratigraphic inversion technique, morphodynamic modeling, and statistical analyses to evaluate the impact of non-uniform flow on the stratigraphy of the Tullig Sandstone in the Western Irish Namurian Basin. The findings refine estimates of channel properties and provide insights into the influence of nonuniform flow on fluvial-deltaic stratigraphy.

Summary: The Neslen and Farrer formations in the Upper Cretaceous are deposits along the western margin of the Western Interior seaway, showing a complex interaction of delta plain, estuarine, and interdistributary bay environments. The study utilizes sedimentary logs, cored wells, and data from other wells to map the distribution of facies associations and identify various processes at play. The research also provides insights into the spatial distribution and stratigraphic control of paralic facies in these formations, which can be valuable for reservoir characterization in different regions.

Summary: There has been a long-standing debate about the origin of long, linear, isolated shallow marine sandstones. Recent studies have shown that shelf sands are mainly derived by reworking of underlying sediment through transgressive erosion, with wave and tidal processes shaping them into discrete ridges and bars. The Late Cretaceous Tocito Sandstone in the Western Interior Seaway is believed to be a transgressive shelf sandstone deposited in retrogradational estuarine to drowned-barrier-system environments with a mixture of tidal and wave influences.

Summary: Surface-based modelling provides an efficient method for generating realistic representations of heterogeneity in reservoir models. By training a neural network to learn the relationship between model inputs and facies identification, and using back-propagation for optimization, the approach allows for conditioning of models to observed data and evaluation of spatial variations in geological heterogeneity.

Summary: Monitoring water movement towards production wells through downhole measurements of self-potential (SP) is a promising new technology. Numerical modeling was used to investigate the behavior of SP during oil production with water injection in different reservoir models. The study found that the magnitude of the SP signal along a production well increased as water approached the well, exceeding the assumed noise level before water breakthrough. The trend of SP increasing at the well with time, along with the shape of the SP profile, were the main indicators of water movement.

Summary: Changes in melt fraction and local bulk composition are crucial in the formation of large volumes of low-crystallinity, silicic magma. Heating/cooling and compaction drive the changes in melt fraction, while reactive flow influences the composition. Compaction decreases melt fraction and forms more refractory composition, while reactive flow increases melt fraction and promotes more evolved composition.

Summary: We propose a new hybrid pressure formulation for modeling multiphase flow and transport in highly heterogeneous porous media using the control volume finite element (CVFE) method. This formulation effectively captures sharp saturation changes at material interfaces by employing a discontinuous pressure approximation. The method divides the porous medium into sub-domains and applies a discontinuous approximation at the sub-domain boundaries while using a continuous approximation elsewhere.

Summary: Despite the wide range of interest and applications, the controls on surface charge of crude oil in aqueous solution are not well understood. This study collates and reviews previous measurements of zeta potential on crude oil, compares and contrasts the results, and reports new measurements of zeta potential on crude oil wetting films and layers. The results show that the zeta potential depends on electrolyte pH and the concentration of divalent ions Ca2+ and Mg2+. Lower pH and higher concentration of these divalent ions lead to more positive zeta potential. The findings have important implications for engineering and industrial activities involving crude oil.
