Investigation on the mechanism of hydraulic fracture propagation and fracture geometry control in tight heterogeneous glutenites

open access: yesEnergy Exploration & Exploitation, 2022
The tight heterogeneous glutenites are typically characterized by highly variable lithology, low/ultra-low permeability, significant heterogeneity, and a less-developed natural fracture system.

PyFrac: A planar 3D hydraulic fracture simulator [PDF]

open access: yesComputer Physics Communications, 2019
Fluid driven fractures propagate in the upper earth crust either naturally or in response to engineered fluid injections. The quantitative prediction of their evolution is critical in order to better understand their dynamics as well as to optimize their

A new chart of hydraulic fracture height prediction based on fluid–solid coupling equations and rock fracture mechanics [PDF]

open access: yesRoyal Society Open Science, 2018
The conventional method to predict hydraulic fracture height depends on linear elastic mechanics, and the typical Gulrajani–Nolte chart fails to reflect fracture height when the net pressure in the fracture is too high.

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

open access: yesAdvanced 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.

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

open access: yesMeitan 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
