Integrated Reservoir Engineering-Geological Evaluation of Fracability and Optimization of Hydraulic Fracture Propagation

Cejing jishu
To optimize the complexity of the fracture network during hydraulic fracturing in reservoirs for enhanced oil and gas recovery, it is essential to integrate geological heterogeneity and engineering parameters, and establish a fracability evaluation model

Flow channelling in a single fracture induced by shear displacement [PDF]

, 2006
The effect on the transport properties of fractures of a relative shear displacement $\vec u$ of rough walls with complementary self-affine surfaces has been studied experimentally and numerically. The shear displacement $\vec u$ induces an anisotropy of

Intercompartmental communication in senescence

FEBS Open Bio, EarlyView.
Senescent cells experience structural changes in the plasma membrane, endoplasmic reticulum, mitochondria, lysosomes, nucleus, and cytoskeleton. These alterations disrupt crosstalk among cellular compartments, impairing vesicular trafficking, contact sites, and molecular flow.

From invasion percolation to flow in rock fracture networks

, 2011
The main purpose of this work is to simulate two-phase flow in the form of immiscible displacement through anisotropic, three-dimensional (3D) discrete fracture networks (DFN).

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control

Advanced Engineering Materials, EarlyView.
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

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

Reactivation of natural fractures network by hydraulic fracturing [PDF]

E3S Web of Conferences, 2020
Modelling the process of induced fracture initiation, propagation and interaction with natural fractures is a very challenged task. Significant progress has been made in recent years in the development of complex fracture models to address the needs for more suitable design tools than the conventional planar fracture models.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

Advanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

The Effect of Hydraulic Fracture Geometry on Well Productivity in Shale Oil Plays with High Pore Pressure

Energies, 2021
We propose three idealized hydraulic fracture geometries (“fracture scenarios”) likely to occur in shale oil reservoirs characterized by high pore pressure and low differential in situ stresses.
