Energy Science &Engineering, EarlyView.This paper presents a hydrate pressure core processing device integrated with a high‐precision active control system to perform nondestructive transfer, cutting, and analysis. To address the limitations of slow dynamic response and high thermal inertia in traditional passive systems, a differentiated control scheme is implemented.

The Linkage Between Near‐Saturated Hydraulic Conductivity and Tritium Leaching
European Journal of Soil ScienceABSTRACT Macropore flow in structured soils is an important process determining the transport of water, contaminants, and nutrients in the soil. Therefore, we also expect a close connection between hydraulic conductivity ( k ( h ...

Assessing saturated hydraulic conductivity from the dielectrically-predicted dry bulk density
, 2020 Direct measurement of saturated hydraulic conductivity (Ks) and dry bulk density (rb) is often laborious, time consuming, and expensive. Predicted dry bulk density (rb-ADR) using Amplitude Domain Reflectometry (ADR) probe has been employed to predict ...

Energy Science &Engineering, EarlyView.The low‐field nuclear magnetic resonance (NMR) measurements are applied to investigate the seepage characteristics of the single rough joint. The purpose of this paper is to investigate the seepage characteristics of granite specimens with single‐joint channel under the different roughness, confining pressures and seepage pressures.

Evaluation of Drillability of the Mahu Conglomerate Formation in Xinjiang, China
Energy Science &Engineering, EarlyView.This graphical abstract illustrates the workflow for developing an optimized prediction model using measurement while drilling (MWD) data. A total of 90 MWD cases are divided into a training set (80%) and a test set (20%). Four logging‐while‐drilling parameters—compensation density, acoustic travel time, resistivity, and neutron porosity—are selected ...

Geological Journal, EarlyView.Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...
