Synthesis of mixed methane-ethylene hydrate with ice powder

Unconventional Resources, 2023
The study of gas hydrate researched by the ice powder method is helpful for us to understand the storage, separation, transportation and transformation of gas on the solid surface.

Black shale deposition during the Early Jurassic: Geochemistry of Pliensbachian and Toarcian sedimentary rocks of the Hunzen Well, Hils Syncline, Northwest German Basin

The Depositional Record, EarlyView.
Our research uses a multidisciplinary approach, including organic and inorganic geochemistry, biostratigraphy, carbon isotope geochemistry and organic petrography to reconstruct depositional conditions and organic matter accumulation during the Pliensbachian and Toarcian.

Research and application of 3D attribute fusion technology based on lithology probability analysis

Scientific Reports
To address the challenges of seismic attribute selection and the low accuracy of characterizing single-phase river channels with a single seismic attribute, a 3D seismic attribute fusion technology based on lithology probability curve analysis has been ...

Transformation Mechanism of a Fault and Its Associated Microstructures in Low-Porosity Rocks: A Case Study of the Tanan Depression in the Hailar-Tamtsag Basin

Journal of Marine Science and Engineering, 2019
Faults have complex internal structures, which can be divided into the fault core and the damaged zone. During the fault formation process, the damaged zone will develop a large number of fractures cross cutting the adjacent host rocks, where the size ...

Deciphering depositional controls and evolution of a lacustrine supradetachment basin through facies analysis: Gördes Basin, Western Türkiye

The Depositional Record, EarlyView.
The lacustrine Gördes Supradetachment Basin was developed along the Simav detachment fault during postorogenic extension in the north of the Menderes Massif in western Anatolia. The basin‐fill succession is represented by alluvial fan, Gilbert‐type delta, shoal‐water delta, foreshore, shoreface, offshore‐transition and peat‐forming mire deposits.

Slip versus dilation tendency parameter space as a tool for prospecting structurally controlled geothermal systems in greenfield: insights from the greater Ruhr region

Deep Underground Science and Engineering, EarlyView.
This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Prediction of Total Organic Carbon Content in Shale Based on PCA-PSO-XGBoost

Applied Sciences
Total organic carbon (TOC) content is an important parameter for evaluating the abundance of organic matter in, and the hydrocarbon production capacity, of shale. Currently, no prediction method is applicable to all geological conditions, so exploring an

Numerical Simulation of Hydraulic Fracturing and Penetration Law in Continental Shale Reservoirs

Processes, 2022
The vertical heterogeneity of continental shale reservoirs is strong, the difference between lithology and stress between layers is large, the weak interface between layers develops, and the hydraulic fracture penetration and expansion are difficult, resulting in poor fracturing transformation effect.
