Journal of GeoEnergy, Volume 2026, Issue 1, 2026.Production forecasting for oil and gas wells is a decisive element of field‐development planning because it directly guides recovery strategy design, production optimisation and risk management. Conventional methods, including empirical decline‐curve analysis (DCA) and full‐physics numerical simulation, are limited either by their inability to capture ...

On a novel approach for optimizing composite materials panel using surrogate models [PDF]
, 2011 This paper describes an optimization procedure to design thermoplastic composite panels under axial compressive load conditions. Minimum weight is the goal. The panel design is subject to buckling constraints.

Estimation of gradients from sparse data by universal kriging [PDF]
Water Resources Research, 2004 The determination of a gradient, or directional derivative, of a spatial variable is a common problem in many Earth science applications. For hydraulic heads, for example, the gradient defines the direction of the groundwater flow and is used in solving groundwater flow and transport equations.

Reliability-based design optimization using kriging surrogates and subset simulation
, 2011 The aim of the present paper is to develop a strategy for solving reliability-based design optimization (RBDO) problems that remains applicable when the performance models are expensive to evaluate.

Statistically Classified Marine Epifaunal Bioregions on the Southern Benguela Margin, South Africa
Ecology and Evolution, Volume 15, Issue 12, December 2025.Marine bioregional maps underpin management and conservation planning. Data‐driven maps based on robust statistical analyses that include uncertainty are new to the marine realm as more data becomes available. The use of Regions of Common Profile models on epifauna data from the Southern Benguela margin distinguished five bioregions related to low ...

Meta-models for structural reliability and uncertainty quantification [PDF]
, 2011 A meta-model (or a surrogate model) is the modern name for what was traditionally called a response surface. It is intended to mimic the behaviour of a computational model M (e.g.

Water Resources Research, Volume 61, Issue 12, December 2025.Abstract Understanding the spatial variation of streambed sediment median grain size (d50) is essential for understanding hydrological, geomorphological, and ecological processes, yet network‐scale patterns remain poorly characterized. Here we combined extensive field sampling (249 locations) with Digital Grain Size analysis and laboratory sieving to ...

Estimating potential soil erosion for environmental services in a sugarcane growing area using multisource remote sensing data [PDF]
, 2013 Characterization of landscapes is crucial in modelling potential soil erosion to ascertain environmental services that are provided by the main land use in the ecosystem. Remote sensing techniques have proved successful in characterization of landscapes.
