Quantitative Identification and Distribution Pattern of Macrolithotype of Coal in Deep Coal Seams of the Daji Block

Energy Science &Engineering, Volume 13, Issue 10, Page 4839-4852, October 2025.
ABSTRACT The construction of a logging response model for macrolithotypes in coal has been successfully completed. This model has enabled delineation of vertical and planar distribution patterns of coal macrolithotypes within the #5 and #8 coal seams of the Daji block, as well as to forecast the distribution of favorable reservoir conditions.

Distribution Simulation of SC‐CO2 Carrying Proppants in Multicluster of Fractures Under Different Perforations

Energy Science &Engineering, Volume 13, Issue 10, Page 4853-4867, October 2025.
A physical model of multicluster fractures in horizontal well with perforation segments. ABSTRACT Supercritical carbon dioxide (SC‐CO2) fracturing is a new type of waterless staged multicluster fracturing. Different from one single fracture, the slurry almost simultaneously flows to multiple fractures in staged multicluster fracturing, resulting in a ...

Pore Structure of Tight Sandstones With Different Sedimentary Microfacies in the Chang 6–Chang 9 Layers, Triassic Yanchang Formation, Wuqi Area, Ordos Basin

Energy Science &Engineering, Volume 13, Issue 10, Page 4900-4916, October 2025.
Taking the Chang 6–Chang 9 layers in the Wuqi area of the Ordos Basin as a case study, this study investigates the pore characteristics of tight sandstones formed under different sedimentary microfacies. The results indicate that tight sandstones associated with distinct sedimentary microfacies exhibit significant variations in pore types, pore size ...

A Rapid Method for the Determination of Coal Seam Gas Pressure Based on Raw Coal Adsorption

Energy Science &Engineering, Volume 13, Issue 10, Page 4660-4673, October 2025.
The method flow of coal seam gas pressure measurement based on raw coal gas adsorption is introduced. ABSTRACT The residual gas pressure of pre‐pumped coal seams is one of the key indices to check the effect of regional outburst prevention. The success rate in direct measurement is low, and it is generally obtained indirectly by use of the Langmuir ...
