Transfer Learning and Benchmarking for Induced Seismic Event Detection: Insights From Oklahoma

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Machine learning models for microseismicity detection are often limited by the scarcity of large and high‐quality labeled data sets in many regions. To address this need, we introduce the Oklahoma Labeled AI Dataset (OKLAD), a manually curated data set compiled by the Oklahoma Geological Survey (OGS).

Experimental Study on the Initiation and Propagation of Multi-Cluster Hydraulic Fractures within One Stage in Horizontal Wells

Energies, 2021
Competitive propagation of fractures initiated from multiple perforation clusters is universal in hydraulic fracturing of unconventional reservoirs, which largely influences stimulation.

The price responsiveness of shale producers: Evidence from micro data

Quantitative Economics, Volume 17, Issue 2, Page 394-430, May 2026.
We show that U.S. shale oil producers exhibit a high degree of short‐run price responsiveness, primarily through the timing of well completions and refracturing. Using a novel monthly well‐level panel covering over 120,000 shale wells across ten states from 2005 to 2019, we document significant supply adjustments to price signals.

Tourism and fracking in the northern Drakensberg area: emerging challenges for tourism sustainability

Discover Sustainability
The South African government has granted licenses to numerous companies to explore the possibility of the extraction of shale gas through hydraulic fracturing of rock (commonly referred to as fracking) in various potentially gas-rich regions in South ...

Methane and Ethane Emission Rates, Intensities, and Trends: Aircraft Mass Balance Insights Over the Denver‐Julesburg Basin, Fall 2021

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Despite a 2.1‐fold increase in oil and gas (O&G) production from 2012 to 2021 in the Wattenberg Field (WF) area of the Denver‐Julesburg Basin (DJB), total methane (CH4) emissions have remained unchanged within measurement uncertainties (26.0 ± 6.8 t/hr in 2012, 24.0 ± 5 t/hr in 2015, and 21.4 ± 5.7 t/hr in 2021), while ethane (C2H6) emissions ...

Benefits of hydraulic fracking [PDF]

, 2013
If an average American heard the word ‘fracking’ ten years ago, chances are he or she would have worried about the manners of the speaker. Today, however, opinions about fracking are solidifying, and battle lines are being drawn, even if understanding ...

Experimental Study on the Effect of Supercritical CO2 on Mechanical Properties and Fracture Characteristics of Longmaxi Shale

Advances in Materials Science and Engineering, 2023
Conventional hydraulic fracturing techniques typically consume large amounts of water when producing shale gas. Fracking fluids may cause environmental pollution. In contrast, supercritical carbon dioxide (scCO2) (above 31.8°C, 7.29 MPa) can displace CH4

A Three‐Stage Model of the Maturation of Nascent Policy Subsystems Toward Stable Advocacy Coalitions, With Evidence From the UK's Response to COVID‐19

Policy Studies Journal, Volume 54, Issue 1, February 2026.
ABSTRACT Policy subsystems are comprised of competing advocacy coalitions, in which public and private political actors with shared belief systems learn from each other and coordinate their strategies in the pursuit of influencing policy making in their favor.
