“…Although we note that the 90% credible intervals do contain the true values of these parameters. A similar story emerges for the results of depth-based structure; f 1 2, f low and f 2 2, f low are well estimated but not as well as the time-based structure, while f 3 2, f low and f 4 2, f low are not, and a high degree of autocorrelation for f 3 2, f low and f 4 2, f low . The estimates of the actual depth structure for both time-based and depth-base, Figure 8a), left side of panels (e) and (f), are comparable to estimates for the two free parameter setting, However, in the four free parameter setting, a 0.5 m package of the shallow assemblage at ∼17 m depth is not captured by the time or depth based models.…”

Estimating the impact of environmental processes on vertical reef development in geological time scales due to complex models and data with missing information is a very challenging task. This paper provides a Bayesian framework called BayesReef, based on PyReef-Core, for the estimation and uncertainty quantification of environmental processes and factors which impact the depth distribution of communities of corals and coralline algae (coralgal assemblages) found in fossil reef drill cores. PyReef-Core is a deterministic, carbonate stratigraphic forward model designed to simulate the key biological and physical processes that determine vertical accretion and assemblage changes in reef drill cores. The results show that explicitly accounting for the temporal structure of the reef core, as opposed to only the depth structure, increases accuracy in parameter estimation. BayesReef provides insights into the complex posterior distributions of parameters in PyReef-Core and provides the groundwork for future research in this area.

Can Offshore Meteoric Groundwater Generate Mechanical Instabilities in Passive Continental Margins?

Offshore meteoric groundwater (OMG) has long been hypothesized to be a driver of seafloor geomorphic processes in continental margins worldwide. Testing this hypothesis has been challenging because of our limited understanding of the distribution and rate of OMG flow and seepage, and their efficacy as erosive/destabilizing agents. Here we carry out numerical simulations of groundwater flow and slope stability using conceptual models and evolving stratigraphy—for passive siliciclastic and carbonate margin cases—to assess whether OMG and its evolution during a late Quaternary glacial cycle can generate the pore pressures required to trigger mechanical instabilities on the seafloor. Conceptual model results show that mechanical instabilities using OMG flow are most likely to occur in the outer shelf to upper slope, at or shortly before the Last Glacial Maximum sea‐level lowstand. Models with evolving stratigraphy show that OMG flow is a key driver of pore pressure development and instability in the carbonate margin case. In the siliciclastic margin case, OMG flow plays a secondary role in preconditioning the slope to failure. The higher degree of spatial/stratigraphic heterogeneity of carbonate margins, lower shear strengths of their sediments, and limited generation of overpressures by sediment loading may explain the higher susceptibility of carbonate margins, in comparison to siliciclastic margins, to mechanical instability by OMG flow. OMG likely played a more significant role in carbonate margin geomorphology (e.g., Bahamas, Maldives) than currently thought.

“…The basin simulation technique that we have used provided an efficient way to quantify the characteristics of the lake basin bottom configuration. Future research that explores the relationship between lake basin bottom configuration and high-quality reservoir development, or the genesis and distribution of highquality reservoirs in general, can utilize this approach (Yang et al 2015;Clavera-Gispert et al 2017).…”

“…Most efforts have been hampered by their reliance on the stratigraphic filling structure and configuration revealed by the current lithostratigraphic unit, as well as the monotonous, near-parallel stratigraphic structure reflected by seismic data. By contrast, a basin simulation approach provides an efficient way to quantify the paleo-tectonic conditions and the evolution of the lake basin (Tong and Mukerji 2017;Clavera-Gispert et al 2017). The approach described in this study could facilitate research into the relationship between the lake basin bottom configuration and the development of a highquality reservoir, as well as the genesis and distribution of high-quality reservoirs, more generally.…”

For many years, oil resource exploration has emphasized the current structural characteristics of potential oil-bearing formations. The traditional view of the Ordos Basin has been that the slope in northern Shaanxi is a gentle westward-dipping monocline that lacks structural traps, such as anticlines. Therefore, it was assumed that structural factors could exert no control over the formation and distribution of the oil reservoirs in the Yanchang Formation. By modeling the evolution and structure of a target layer in the Chang-8 reservoir during its hydrocarbon accumulation period, combined with a comprehensive analysis of the distributional characteristics of the Chang-8 oil reservoir, we found a strong link between paleo-slopes and paleo-highs in the target layer and the modern distribution of tight oils. The paleo-structural characteristics of the target layer clearly exhibit control over the Chang-8 reservoir. We have proposed a new understanding and method for tight oil exploration, which is based on the recovery of the paleo-geomorphology of the target layer during the hydrocarbon generation period. It incorporates a number of key controls over tight oil accumulation and represents an evolution in the mindset suggested for tight oil exploration in the Ordos Basin.
