Microbial Community Dynamics in the Hydraulic Fracturing Water Cycle from Two Newly Fractured Shale Gas Wells in the Duvernay Formation, AlbertaDownload
The microbial ecology of the hydraulic fracturing water cycle may influence the efficiency of shale gas production and strategies for water reuse and treatment. In this study, microbial community dynamics were tracked by sequencing of 16S rRNA genes coupled with enumeration of live/dead cells in...
Isotope Geochemistry of Natural Gas from the Horn River Basin: Understanding Gas Origin, Storage and Transport in an Unconventional Shale PlayDownload
Devonian shales of the Horn River Basin, northeast British Columbia are recognized key targets for unconventional shale gas production in Canada. Recent studies show gas isotope geochemistry in several unconventional shale plays worldwide differ from conventional hydrocarbon reservoirs and carbon...
Analysis of Water Flowback and Gas Production Data for Fracture Characterization in the Horn River BasinDownload
Shale gas is one of the most promising energy resources due to its wide distribution, abundant reserves, and low pollutant emissions to the environment. Although shale gas plays usually have very low permeability and porosity, the use of horizontal drilling and hydraulic fracturing technologies...
Analytical and Experimental Study of Gas Flow Regime in the Matrix and Fractures of Shale Gas ReservoirsDownload
One of the most significant differences between conventional and unconventional gas resources is the ultra-low matrix permeability of unconventional gas reservoirs such as shale, coal and tight gas. Matrix permeability of shales is an elusive but important parameter in characterizing shale gas...
