Quantitative Evaluation of Sand Body Connectivity Based on the Support Vector Machine Algorithm: A Case Study of the Putaohua Oil Reservoir in the Daqing Oil Field, Songliao Basin, China

Energy Science &Engineering, EarlyView.
A support vector machine (SVM) algorithm was applied to quantitatively predict the connectivity of the sand bodies. Verification using dynamic and static data demonstrated that the prediction accuracy of the algorithm reached 88%. The quantitative sand body connectivity results were used to establish a single sand body model.

Effect of Perforation Methods on Fracture Propagation in Gelatin‐Based Matrices

Energy Science &Engineering, EarlyView.
ABSTRACT The development of unconventional hydrocarbon resources has positioned hydraulic fracturing as a pivotal technology in shale oil extraction, where understanding fracture propagation mechanisms is critical for reservoir stimulation optimization. This study employs gelatin‐based visualized experiments to systematically investigate the effects of

Porosity Optimization Model to Characterize Gas Seepage Behavior in Longwall Mining Gobs: An Application Case and Simulation Analysis

Energy Science &Engineering, EarlyView.
ABSTRACT The degree of fragmentation of coal rock determines the porosity distribution of goaf porous media, which can be expressed using empirical formulas. However, this method fails in regions with nonuniform caving, dynamic disturbances, or deep high‐stress conditions. Therefore, this study developed a porosity optimization model comprising A and B

Stress Relief Effects of Roof‐Cutting at the Junction Zone Between Gob‐Side Entry and Stope Within Extra‐Thick Coal Seams

Energy Science &Engineering, EarlyView.
The analytical model of severe ground pressure in JZGS: (a) Overlying rock strata structure above the stope and gob‐side entry; (b) in situ monitoring of advanced and lateral abutment pressures. Many studies have demonstrated that the overlying strata above the stope and gob‐side entry fracture and collapse at specific angles [28‐30], forming broken ...
