Experimental study on hydrate saturation evaluation based on complex electrical conductivity of porous media

Xing, Lanchang; Niu, Jiale; Zhang, Shuli; Cao, Shengchang; Wang, Bin; Lao, Liyun; Wei, Wei; Han, Weifeng; Ge, Xinmin; Wei, Zhoutuo (Elsevier, 2021-09-23)

The hydrate saturation is a critical parameter in the evaluation of gas hydrate reservoirs. The complex characteristics of hydrate-bearing sediments pose challenges to the reliability of conventional geophysical techniques ...
Numerical study on complex conductivity characteristics of hydrate-bearing porous media

Xing, Lanchang; Qi, Shuying; Xu, Yuan; Wang, Bin; Lao, Liyun; Wei, Wei; Han, Weifeng; Wei, Zhoutuo; Ge, Xinmin; Aliyu, Aliyu M. (Elsevier, 2021-07-13)

The complex conductivity method is frequently used in hydro-/petro-/environmental geophysics, and considered to be a promising tool for characterizing and quantifying the properties of subsurface rocks, sediments and soils. ...
A permittivity-conductivity joint model for hydrate saturation quantification in clayey sediments based on measurements of time domain reflectometry

Xing, Lanchang; Gao, Liang; Ma, Zisheng; Lao, Liyun; Wei, Wei; Han, Weifeng; Wang, Bin; Gao, Muzhi; Xing, Donghui; Ge, Xinmin (Elsevier, 2024-04-03)

Hydrate saturation (Sh) is one of the key parameters for resource assessment of hydrate reservoirs and production optimization of natural gas. There are still significant challenges in determining the Sh in clayey formations. ...
Pore-scale modelling on complex-conductivity responses of hydrate-bearing clayey sediments: implications for evaluating hydrate saturation and clay content

Xing, Lanchang; Zhang, Huanhuan; Wang, Shuo; Wang, Bin; Lao, Liyun; Wei, Wei; Han, Weifeng; Wei, Zhoutuo; Ge, Xinmin; Deng, Shaogui (Elsevier, 2022-12-30)

A majority of the accumulated gas hydrates exist in fine-grained unconsolidated sediments with clays, which pose challenges to reservoir evaluation with resistivity-based techniques. Characteristic electrical parameters ...
Saturation estimation with complex electrical conductivity for hydrate-bearing clayey sediments: an experimental study

Xing, Lanchang; Zhang, Shuli; Zhang, Huanhuan; Wu, Chenyutong; Wang, Bin; Lao, Liyun; Wei, Wei; Han, Weifeng; Wei, Zhoutuo; Ge, Xinmin; Deng, Shaogui (Springer, 2023-04-04)

Clays have considerable influence on the electrical properties of hydrate-bearing sediments. It is desirable to understand the electrical properties of hydrate-bearing clayey sediments and to build hydrate saturation (Sh) ...
