Water Insecurity, Social Perspectives, and Health Impacts in Private Drinking Water Sources in Pennsylvania: Two Systematic Literature Reviews

open access: yesWIREs Water, Volume 13, Issue 1, January/February 2026.
The two systematic reviews identified that social perspectives and health impacts associated with water insecurity among private water sources users relate to a range of water safety risks, organoleptic properties, health effects, and coping strategies.

Stochastic Risk and Uncertainty Analysis for Shale Gas Extraction in the Karoo Basin of South Africa

open access: yesAbstract and Applied Analysis, 2014
We made use of groundwater flow and mass transport equations to investigate the crucial potential risk of water pollution from hydraulic fracturing especially in the case of the Karoo system in South Africa.

Anisotropy in Fracking: A Percolation Model for Observed Microseismicity

open access: yes, 2014
Hydraulic fracturing (fracking) using high pressures and a low viscosity fluid allow the extraction of large quantiles of oil and gas from very low permeability shale formations.

The “Fracking” technique: a novel approach to crack deep calcified plaque in the common femoral artery with hydraulic pressure

open access: yesCVIR Endovascular, 2021
Background The patency achieved by conventional peripheral interventions for atherosclerotic lesions in the common femoral artery (CFA), called the “no stenting zone”, is not superior to that achieved by surgical endarterectomy due to calcified plaque ...

Public Perceptions of High-Volume Hydraulic Fracking and Deep Shale Gas Development [PDF]

open access: yes, 2013
This document is one of the seven technical reports completed for the Hydraulic Fracturing in Michigan Integrated Assessment conducted by the University of Michigan. During the initial phase of the project, seven faculty-led and student-staffed teams focused on the following topics: Technology, Geology/Hydrogeology, Environment/Ecology, Human Health ...

Hardening and Hollowing Out Private Property: Rentiership, Dispossession, and Planetary Extraction in the Marcellus Shale

open access: yesAntipode, Volume 58, Issue 1, January 2026.
Abstract Southwestern Pennsylvania (SWPA) has long been an energy extractive periphery, continuously remade through cycles of dispossession and accumulation. Here we examine the changing dynamics of private property in these cycles and its central role in the latest phase of extraction—unconventional oil and gas development (UOGD).

Study on Fault Activation Evaluation Mechanism and Sensitivity Analysis in Shale Gas Hydraulic Fracturing

open access: yesGeofluids, 2023
Shale gas hydraulic fracturing usually activates nearby faults and makes them slip. In horizontal wells, fault slip can result in serious casing deformation.

US Foreign Policy and the Gulf States: Changing Dynamics in a Multipolar World

open access: yesWorld Affairs, Volume 188, Issue 4, Winter 2025.
ABSTRACT This article focuses on US foreign policy toward the Gulf from Obama's Pivot to Asia to the initial period of the second Trump administration. It situates the role of the US within the broader context of the global energy transition and the Gulf states as geopolitical actors in a multipolar world order.

Investigation of Hydraulic Fracturing Behavior in Heterogeneous Laminated Rock Using a Micromechanics-Based Numerical Approach

open access: yesEnergies, 2019
Understanding hydraulic fracturing mechanisms in heterogeneous laminated rocks is important for designing and optimizing well production, as well as for predicting shale gas production. In this study, a micromechanics-based numerical approach was used to
