Numerical simulation and engineering application of comb-shaped directional long borehole hydraulic fracturing under different arrangement of holes

open access: yesMeikuang Anquan, 2021
In order to avoid the blindness of the hydraulic fracturing of the directional long borehole in coal mine 2130 of Xinjiang Coking Coal Group, and to accurately grasp the extension and expansion of hydraulic fracturing under different hole layout methods,

Hydraulic Fracturing

open access: yes, 2019
Hydraulic fracturing or also know as fracking, the removal of natural gas and oil from shale rock, took off in the 1990s, but the anti-fracking movement didn't start taking notice until 2005. Fracking began to take place in the the south and the middle of the United States, because those areas are not known for have environmental activists.

Recent comprehensive review for extended finite element method (XFEM) based on hydraulic fracturing models for unconventional hydrocarbon reservoirs

open access: yesJournal of Petroleum Exploration and Production Technology, 2020
Hydraulic fracturing has been around for several decades since 1860s. It is one of the methods used to recover unconventional gas reservoirs. Hydraulic fracturing design is a challenging task due to the reservoir heterogeneity, complicated geological ...

Hydraulic fracturing proppants [PDF]

open access: yesCerâmica, 2018
Abstract Hydrocarbon reservoirs can be classified as unconventional or conventional depending on the oil and gas extraction difficulty, such as the need for high-cost technology and techniques. The hydrocarbon extraction from bituminous shale, commonly known as shale gas/oil, is performed by using the hydraulic fracturing technique in unconventional ...

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

open access: yesAdvanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Study on variation law of coal disturbance stress in hydraulic fracturing test

open access: yesMeikuang Anquan, 2023
In order to explore the variation of disturbance stress in the coal seam around the fracturing borehole in the process of hydraulic fracturing, taking the 1703 coal face of Junlian Jinzhong Coal Mine Company as the test site, on the basis of determining

Rheocasting versus Die Casting: An Insight into the Low‐Cycle Fatigue Behavior of AlSi7Mg0.6

open access: yesAdvanced Engineering Materials, EarlyView.
The study compares rheocast lightweight components with high‐pressure die cast materials regarding microstructure and fatigue behavior. Rheocast process offers higher efficiency due to lower casting temperatures. Despite some microstructural differences, both processes show similar strengths (yield strength 125 MPa, tensile strength 240 MPa).
