Transient Temperature Impact on Deep Reservoir Fracturing

Geofluids, 2021
Hydraulic fracturing enables the commercial development of unconventional resources in shales and tight formations. The conductivity and complexity of created fractures are critically dependent on the rheology of fracking fluid and the mechanics ...

Partisan Cities: How State‐Local Political Alignment Shapes Credit Risk and Information Processing in the Municipal Bond Market

Journal of Accounting Research, EarlyView.
ABSTRACT This paper studies how partisan alignment between city leaders and state governors shapes information processing and bond pricing in the municipal bond market. Using a novel data set on 1,045 U.S. cities from 2005 to 2019, we show that cities with the same political affiliation as the state governor face 9 basis points lower borrowing costs ...

Prospects of "Slate Revolution" and Problem of Power Industry of China

Vestnik MGIMO-Universiteta, 2013
The remarkable results of “shale gas revolution” in the USA have provoked a huge interest in Chinese energy circles. Beijing seriously considers the prospects of developing its abandoned domestic shale gas resources, which might result in a second “shale

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.

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 ...

Study on catastrophe mechanism of hydraulic fracturing fracks initiation in radial boreholes

Geomechanics and Geophysics for Geo-Energy and Geo-Resources, 2020
Radial drilling hydraulic fracturing has become a new stimulation method. The hydraulic fracturing effect of radial drilling on site is not ideal, and the stimulation effect of some wells is not obvious. The hydraulic fracturing effect of radial drilling is closely related to the crack initiation position after radial drilling fracturing.

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

Abstract 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.

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

CVIR 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 ...
