Machine Learning‐Driven Classification and Production Capacity Prediction of Tight Sandstone Reservoirs: A Case Study of the Taiyuan Formation, Ordos Basin

open access: yesEnergy Science &Engineering, Volume 14, Issue 5, Page 2514-2538, May 2026.
On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...

Spatial Layout of Trees on Farms Influences Magnitude and Timing of River Flow Peak

open access: yesHydrological Processes, Volume 40, Issue 5, May 2026.
Effectiveness of agroforestry as a lowland NFM strategy is spatially modelled for a range of planting layouts. Peak flow for a 10‐year storm was attenuated by 2.6% and delayed by 19 min with just 0.6% catchment tree coverage under riparian planting alone. Increasing coverage provided a strongly diminishing return in flood peak attenuation.
