Fully three-dimensional propagation model of horizontal borehole hydraulic fractures in strata under the effect of bedding planes

Energy Exploration & Exploitation, 2018
The bedding plane effect will occur when hydraulic fractures propagate to the bedding plane in sedimentary strata, resulting in the “≠,” “工,” or “/” shaped fracture morphology.

Experimental investigation on hydraulic fracture propagation of coal shale reservoirs under multi-gas co-production

Yantu gongcheng xuebao, 2022
The gas-bearing formations, including shale, coal and limestone rock, are alternately and vertically developed in coal shale reservoirs. Multiple unconventional natural gases can be exploited together through the hydraulic fracture longitudinally ...

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

Advanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Fracture propagation model accounting for intersection among hydraulic fractures and natural fractures in three-dimensional space

Meitan xuebao
Due to development of a large number of natural fractures in unconventional gas and oil reservoirs, the fracture expansion patterns during hydraulic fracturing are complicated. It is crucial to clarify the intersecting and expanding mechanical mechanisms

Hydraulic Fracturing Growth in Fracture Reservoirs Using Analytical and Numerical Simulation: T-Type Intersections

Journal of Chemical and Petroleum Engineering, 2013
Hydraulic fracture diagnostics have highlighted the potentially complex natural of hydraulic fracture geometry and propagation. This has been particularly true in the cases of hydraulic fracture growth in naturally fractured reservoirs, where the induced

MAPPING HYDRAULIC FRACTURE USING SHEAR WAVE [PDF]

, 2018
It has become critical to understand the location of hydraulic fracture and the extent to which it stimulates a reservoir to plan future drilling and completions. Various methods have been used to map the fracture propagation.
