Effect of single straight, intersecting and T-shaped natural fractures on horizontal wellbore stability in shale reservoirs

Journal of Petroleum Exploration and Production Technology
The development of natural fractures can easily lead to horizontal wellbore instability caused by stress concentration after drilling in shale reservoirs, which is not conducive to the safe development of shale gas, but how different natural fractures ...

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Frontal Sinus Fractures: Current Strategy of Diagnostics and Treatment

, 2013
Introduction. Frontal sinus fracture, despite rather low frequency of their occurrence, is one of the most complex problems of modern cranio-maxillofacial surgery, and strategies for their treatment are controversial.

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing

Advanced Materials, EarlyView.
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

Impact of Inter‐Well Stress Interference on Multifracture Propagation in Tight Reservoirs

Energy Science & Engineering
Fracture interference is commonly observed during hydraulic fracturing operations in tight reservoirs. While such interference can contribute to the development of complex fracture networks, it can also impede fracture initiation and propagation ...

Hydraulic Fracturing in Formations with Permeable Natural Fractures

, 2013
The recently developed Unconventional Fracture Model (UFM*) simulates complex hydraulic fracture network propagation in a formation with pre-existing closed natural fractures, and explicitly models hydraulic injection into a fracture network with multiple propagating branches [1].
