... of multiple fractures in horizontal wells. Eight artificial rocks, each with dimensions of 400 mm ×400 mm × 400 mm and equipped with two horizontal wells, are sequentially fractured. The effects of the horizontal stress difference, the fracturing sequence, and the arrangement of perforations were discussed...

... of blasting-induced damage. Adjustments and optimizations are applied to the blasting sequence, blasthole layout and explosive charge weight. The findings indicate that the scope of rock damage is reduced with the increasing of in-situ stress, there exists a transition of rock failure mode from tensile-shear...

... of managing the yielding of the merge zone and minimizing worker exposure to the yielding stress front. A stope-scale example would be in the typical primary-secondary stope mining sequence, where secondary stopes are intentionally left behind to support an ever-increasing stress-load. As the leading primary...

... ABSTRACT Stimulated Reservoir Volume (SRV) fracturing of horizontal wells significantly increases oil and gas production by generating a large amount of high-permeability main and branch fractures. This study attempts to explores the effect of fracturing sequences on smaller-scale fractures...

... perturbation of the seismically active fault. In this paper, three case studies are described demonstrating that seismicity follows an Omori decay, consistent with earthquake aftershock sequences. The Omori decay characteristics thereby provides an important framework to distinguish between fault ‘relaxation...

... ABSTRACT: The fracturing sequence could affect the stress disturbance, which is main factor of the formation of a complex fracture network. The characteristics of inter-fracture interference under different fracturing sequences needs to be studied. We carried out the hydraulic fracturing...

To this end, we propose to construct an efficient and robust Vs prediction model using Gated Recurrent Unit (GRU) network, which could deeply mine and connect the information in Vs sequence and other logging sequences (e.g., gamma ray, resistivity, neutron...

... prediction model is proposed. The results show that when stick-slip occurs, the amplitude of triaxial acceleration vibration is larger, the power spectrum density is smaller than normal drilling, and there are apparent peaks. The triaxial acceleration is a stationary non-white noise sequence. The stick-slip...
