Key experimental technologies and their development directions for the exploration and production of deep coalbed methane
Published 2025-01-01“…However, the exploration and production of deep CBM are still confronted with many technical challenges, and there is a lack of studies on key experimental technologies related to the geological characteristics and engineering assessment of deep CBM reservoirs, the occurrence characteristics and production mechanisms of gas and water, the formulation of production systems, and methods for enhanced CBM recovery. Advances in ResearchGiven the characteristics of deep coal seams and CBM, this study identifies four challenges in the exploration and exploitation of deep coal seams: the collection of large coal samples, the high-temperature, high-pressure, and high-stress in-situ conditions, high-precision characterization and desorption of sub-nano- to nano-scale micropores, and the accurate determination of gas content. …”

Temporal resolution trumps spectral resolution in UAV-based monitoring of cereal senescence dynamics
Published 2024-12-01“…Conclusions Remote-sensing based proxies derived from both RGB and multispectral sensors can capture the senescence process accurately. The sub-sampling emphasized the importance of timely and frequent assessments, but also highlighted the need for robust methods that enable such frequent assessments to be made under variable environmental conditions. …”
