Analysis of Water Flowback and Gas Production Data for Fracture Characterization in the Horn River Basin
DownloadSpring 2019
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 Reservoirs
DownloadFall 2016
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...

Experimental Tight Rock Characterization and Surfactant Screening for Hydraulic Fracturing Operations
DownloadSpring 2023
Recently, unconventional resources, especially tight and shale reservoirs, have developed rapidly because of advances in horizontal drilling technologies and hydraulic fracturing technique. Based on the annual energy outlook of the Energy Information Administration, tight oil production in the US...

Isotope Geochemistry of Natural Gas from the Horn River Basin: Understanding Gas Origin, Storage and Transport in an Unconventional Shale Play
DownloadFall 2014
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...

Microbial Community Dynamics in the Hydraulic Fracturing Water Cycle from Two Newly Fractured Shale Gas Wells in the Duvernay Formation, Alberta
DownloadFall 2017
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...

Spring 2022
Hydraulically fractured horizontal wells are widely adopted for the development of tight or shale gas reservoirs. The presence of highly heterogeneous, multi-scale, fracture systems often renders any detailed characterization of the fracture properties challenging. The discrete fracture network...

Numerical Simulation of Shale Gas Production and Fracturing Fluid Distribution: Integration of Apparent Permeability and Secondary Fracture Network Modeling
DownloadFall 2019
Complex flow mechanisms are encountered in shale matrix due to the presence of nanopores. Numerous apparent permeability models have been proposed to capture the ensuing non-Darcy flow behavior. However, these models are not readily available in most commercial reservoir simulators, and ignoring...

Quantifying Matrix and Fracturing Water Contributions to the Total Produced Water Based on the Water-flowback Responses
DownloadFall 2023
The main goal of this thesis is to evaluate the possibility of quantifying matrix and fracturing water contributions to the total produced water based on the water-flowback responses without analyzing water chemical data. We analyze flowback production data of 380 multi-fractured horizontal oil...

The sorption characteristics of inorganic and organic compounds found in hydraulic fracturing flowback and produced water: Implications for fate and transport
DownloadFall 2019
In recent years, due to increasing energy demands, hydraulic fracturing operations for recovering unconventional hydrocarbon resources has increased. Wastewater recovered is referred to as flowback and produced water (FPW), and is often saline, contains numerous organic and inorganic...

Spring 2015
Hydraulic fracturing treatment has been increasingly applied to stimulate shale gas reservoirs. During hydraulic fracturing, a large amount of fracturing water is injected into the target formation. However, only a small fraction of injected fluid, typically 10 to 20 %, can be recovered during...
