A Generic Fracture Conductivity Model for Partially Propped Fracture Networks with Proppant Embedment and Proppant Pack Deformation

open access: yes
Hydraulic fracturing involving proppant injection is currently the most effective technology to stimulate tight, unconventional reservoirs. The conductivity offered by the created propped and unpropped fracture segments is directly linked to the well ...

Practical Well Test Analysis of a Hydraulically Fractured Low Permeability Gas Reservoir: A Case History

open access: yesJournal of King Saud University: Engineering Sciences, 2008
The primary objective of hydraulic fracturing is to create a propped fracture with sufficient conductivity and length to amplify or at least optimize well performance of low permeability tight gas reservoir.

Design Internal Forces of Non‐Dissipative Members in CBFs With Regular and Irregular Brace Configurations

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 14, Page 3443-3465, November 2026.
ABSTRACT Steel Concentrically Braced Frames (CBFs) are widely used in seismic regions, with chevron and split‐X configurations commonly adopted for their structural efficiency and architectural flexibility. Although extensive research has been carried out on these systems, the effectiveness of the formulations available in the literature for estimating

Covalent Organic Frameworks in Smart Food Packaging: Advances, Challenges, and Future Prospects

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT Food preservation challenges have positioned packaging as a rapidly evolving, innovation‐driven field, with smart packaging offering transformative solutions. Among advanced materials, covalent organic frameworks (COFs) have attracted growing attention due to their permanent porosity, structural tunability, high surface area, and chemical ...

A semi-analytical fracture high-conductivity location diagnostic method for vertically fractured wells in multilayered reservoirs: field case study

open access: yesFrontiers in Energy Research
Deep multilayered reservoirs are usually developed using multilayered fracturing techniques; however, the non-uniform placement of proppant causes uneven distribution of fracture conductivity.

Reflections on the Application of Aboriginal Community Controlled Health Organisations' Research Principles in a Photovoice Food Security Study

open access: yesHealth Promotion Journal of Australia, Volume 37, Issue 4, October 2026.
ABSTRACT Issue Addressed The conduct of ethical research: the application of ethical practice as guided by Aboriginal Community Controlled Health Organisations' (ACCHOs) research principles. Methods A synthesis of two ACCHOs' research principles was conducted, followed by a reflection on the practical application of these principles in a photovoice ...

Reaction‐Driven Crack Propagation Controlled by Vein Extension in a Dilute Fracture System

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Permanent mineral trapping of CO2 ${\text{CO}}_{2}$ in ultramafic rocks can be accelerated if carbonate precipitation wedges open microcracks and sustains crack growth, thereby increasing permeability and reactive surface area. We develop a vein‐extension controlled model for carbonation reaction‐driven cracking in a dilute fracture system ...

On the Destruction and Humanitarianisation of the Health System in Gaza and the Need for a Biopolitical Bioethics

open access: yesBioethics, Volume 40, Issue 8, Page 793-807, October 2026.
ABSTRACT This paper examines Israel's destruction and ‘humanitarianisation’ of Palestinian health systems, arguing that this should be understood as an instance of ‘necropolitics,’ as conceived by Achille Mbembe. We review the extensive, long‐term destruction of health systems in Palestine before 7 October 2023 and the catastrophic acceleration of that
