Gels, 2023 Oil-based drilling fluids are widely used in challenging wells such as those with large displacements, deepwater and ultra-deepwater wells, deep wells, and ultra-deep wells due to their excellent temperature resistance, inhibition properties, and ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract We propose a variational autoencoder framework to directly assess uncertainties in subsurface models produced by single‐ and multiparameter full waveform inversion (FWI). The new method does not require pretraining on labeled data, thus it significantly reduces computational cost and storage requirements.

Simulated Ocean Oxygen Under Miocene Boundary Conditions
Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.Abstract The Miocene Climatic Optimum (MCO; 16.9–14.7 Ma) was a warm interval with atmospheric CO2 ${\text{CO}}_{2}$ comparable to end‐of‐21st‐century projections under intermediate emission scenarios. Proxy records indicate the Oxygen Minimum Zone (OMZ) in the Eastern Tropical Pacific (ETP) was small or non‐existent during the MCO, expanding only when

Temperature, Sea Ice, Depth, and Traits Drive Fish Distributions in the Barents Sea
Diversity and Distributions, Volume 32, Issue 10, October 2026.ABSTRACT Aim Marine species are increasingly impacted by climate change, forcing them to adapt or redistribute to remain within their environmental niches. How the combined effects of environmental gradients and species traits influence the distribution of species with distinct biogeographic affinities remains poorly understood.

Methodology for kick tolerance calculation and well killing in deepwater drilling
Natural Gas Industry B, 2016 Kick tolerance is a key parameter to indicate whether shut-in operation can be carried out safely and a proper well killing method should be chosen in well drilling.

Marine Mammal Science, Volume 42, Issue 4, October 2026.ABSTRACT Human interactions, specifically fishery entanglements (FI) and vessel strikes (VI), threaten marine mammals, including the Barataria Bay Estuarine System (BBE) Stock of common bottlenose dolphins (Tursiops truncatus). We reviewed whole‐body photographs to estimate the prevalence of sublethal entanglement and vessel strike scars for 227 ...

Energy Science &Engineering, Volume 14, Issue 9, Page 4282-4299, September 2026.Flow characteristics and pressure loss mechanisms of a reverse circulation converter in dual‐wall drill pipes are systematically investigated using CFD and response surface methodology. The results reveal the dominant role of inertial dissipation and provide a predictive framework for optimizing converter design and operational parameters. ABSTRACT The
