The local economic impact of shale gas extraction [PDF]

Regional Studies, 2017
Advocates of UK shale gas expansion have focused upon predicted national economic benefits, but local and/or regional impact has been largely neglected. This paper seeks to address this deficit by creating a unique dataset, combining industry data with consumer and supply chain surveys, thereby overcoming the current absence of suitable secondary data.

Investigation of Large-Diameter Borehole for Enhancing Permeability and Gas Extraction in Soft Coal Seam

Geofluids, 2020
The efficiency of gas extraction from the soft coal seam with ultralow permeability is low. Gas extraction with large-diameter borehole is proposed to deplete gas content for preventing gas outburst disaster in this study.
