Emission scenarios of a potential shale gas industry in Germany and the United Kingdom

The shale gas debate has taken center stage over the past decade in many European countries due to its purported climate advantages over coal and the implications for domestic energy security. Nevertheless, shale gas production generates greenhouse gas and air pollutant emissions including carbon dioxide, methane, carbon monoxide, nitrogen...

Future European shale gas life-cycle GHG emissions for electric power generation in comparison to other fossil fuels

The carbon footprint of shale gas combusted in Europe was estimated from nine European shale gas plays as potential production regions. Greenhouse gas emission sources during shale gas production, such as fugitives from hydraulic fracturing or combustion emissions from horizontal drilling, were added to emissions occurring for conventional gas...

Natural-Fracture Reactivation in Shale Gas Reservoir and Resulting Microseismicity

A geomechanical and fluid-flow coupled model was developed to simulate natural-fracture-network reactivation during hydraulicfracturing treatments in shale gas reservoirs. The fractures were modelled using the continuum approach in a commercial finitedifference code, labeled the "softening ubiquitous joints" model, with randomly distributed...

Addressing uncertainties in estimates of recoverable gas for underexplored Shale gas Basins

Uncertainties in upfront predictions of hydraulic fracturing and gas production of underexplored shale gas targets are important as often large potential resources are deduced based on limited available data. In this paper, uncertainties are quantified by using normal distributions of different input parameters in wellbased models for hydraulic...

Sweet spot identification and smart development -An integrated reservoir characterization study of a posidonia shale of a posidonia shale outcrop analogue

Shale gas reservoir stimulation procedures (e.g. hydraulic fracturing) require upfront prediction and planning that should be supported by a comprehensive reservoir characterization. Therefore, understanding shale depositional processes and associated vertical and lateral sedimentological variability is key in predicting the character and...

Integrated reservoir characterization of a Posidonia Shale outcrop analogue: From serendipity to understanding

Shale gas reservoir stimulation procedures (e.g. hydraulic fracturing) require upfront prediction and planning that should be supported by a comprehensive reservoir characterization. Therefore, understanding shale depositional processes and associated vertical and lateral sedimentological variability is key in predicting the character and...

The Geopolitics of Shale Gas: The Implications of the US' Shale Gas Revolution on Intrastate Stability within Traditional Oil- and Natural Gas-Exporting Countries in the EU Neighborhood

The US’ shale gas revolution could in the long term destabilize traditional oil- and gas exporters in the European Union (EU) neighborhood: A combination of substitution effects and greater energy efficiency, could put pressure on the price of oil, leading to fiscal difficulties in traditional hydrocarbon exporting countries.

Upfront predictions of hydraulic fracturing and gas production in underexplored shale gas basins: Example of the posidonia shale formation in the Netherlands

Upfront predictions of hydraulic fracturing and gas production of potential shale gas targets in Europe are important as often large potential resources are deduced without detailed knowledge on the potential for successful stimulation. Such predictions are challenging as they need to be based on limited available data, i.e. without well tests...

New insights from jurassic shale characterization: Strengthen subsurface data with outcrop analogues

This study shows the first results of an ongoing project on the characterization of variations in lithological- and geomechanical properties of targetted gas shale formations. The aim of this study is to get an increased insight into both the fraccability and productivity of a shale formations. Ultimately, this can lead to better localization of...

3D numerical modeling of shale gas stimulation and seisimicity

The economic production from shale gas reservoir depends on the success of hydraulic stimulation, which is aimed at the creation of a permeable complex fracture network. This is achieved by the reactivation of a natural fracture network; however, the reactivation may be accompanied by unwanted seismicity. Coupled modelling is required to...
