White Sands
I’ve constructed a narrative thread that connects experiences, events, and artworks made during my time in graduate school. This narrative, which has the perspective of time, betrays the firsthand experience of wayfaring through the projects and places I describe. The narrative loosens as it …

Daytona sands
<p>Layered with elements of tension, high-risk suspense, and an unlikely romance, “Daytona Sand” is a work of long-form fiction that introduces readers to August Peterson, an adolescent girl growing up in the throws of the ever-growing opioid epidemic on the coast of Daytona Beach, Florida. After …

The Alberta Oil Sands
<p>The Alberta oil sands near Ft. McMurray, Alberta, have been estimated by many to contain at least 300,000,000,000 bbls of oil, and would therefore be classed as the largest potential oil field in the world. The oil sand deposit is considered to be non-marine in origin and consists mainly of very …

Electrokinetic Dewatering of Oil Sands Tailings
Oil sands tailings are the final product of oil sands processing and in the form of slurry with very low solid content. After sedimentation, due to a low hydraulic conductivity of the tailings, both dewatering and consolidating the tailings are difficult. Since electrokinetic (EK) is an effective …

Force Chain Detection in Unconsolidated Sands
Understanding the geomechanical properties of rocks is vital in petroleum engineering. The compressibility of a formation often correlates directly with the productivity of that reservoir. It is a common practice to extract core samples from reservoirs for the purposes of obtaining the reservoir …

Energy Recovery from Oil Sands Reservoirs
Alberta's oil sands are the third largest proven crude oil reserve in the world, after Saudi Arabia and Venezuela. The proven reserve is ~165.4 billion barrels. At original reservoir conditions, for in-situ methods, the bitumen is too viscous to extract directly with viscosities of the order of …

Seismic Response and Liquefaction of Saturated Sands
… potential and seismic response of saturated sands. Method treats the saturated granular soil system as a two-phase nonlinear medium with constituent materials being the granular solid skeleton and the pore water. An elasto-plastic stress-strain rule is developed to simulate the behavior of …

A study of the sands of Virginia
… of Virginia. The chief stress is laid on those sands coming from points west of the Blue Ridge Mountains. The reasons for stressing the western and southwestern Virginia sands, as they will be called throughout this paper, will be brought out in the pages that follow. The study and investigation …

Tar sands or scar sands: the oil sands are a huge benefit to the Canadian economy but is this at the expense of the environment that is left behind for future generations?
… makes unconventional sources of oil like the tar sands seem more economically appealing. Canada’s tar sands are in an advantageous and unique position. As the biggest deposit of unconventional oil and gas in the world and sitting in a politically stable source country, there is vast international …

Shear behaviour and stiffness of naturally cemented sands
… and stiffness of two naturally cemented sands: a calcarenite with relatively low densities, weak particles and strong bonding and a silica sandstone with high densities, strong particles and weak bonding. Comparative studies were also undertaken on their corresponding reconstituted soils …

Treatment of Oil-Sands Produced Water by Electrocoagulation
In Alberta, the oil-sands industry plays an important role in the local economy. However, the industry consumes a large amount of water, which is not economical. Significant capital and operating costs have been invested by the oil industries in the treatment of this contaminated water every year. …

Modeling and Analysis of Cyclic Behavior of Sands
… of this study is to develop a material model for sands based on the concepts of the theory of plasticity. The model could be used in finite element analysis of transient behavior of soil structure under dynamic loading. The model, to qualify as an acceptable constitutive law for cyclic behavior of …

An Experimental Study on the Aging of Sands
… of time-dependent changes in the proper-ties of sands, or aging effects. Most of these aging effects are of increases in the cone penetration resistance. Time-dependent increases in penetration resistance have been measured in hydraulically placed fills and freshly densified deposits, with the …

Mapping Groundwater Discharges to Rivers near Oil Sands Projects
… discharges in the western Canadian oil sands region impact river water quality. Mapping groundwater discharges into rivers in the oil sands region is important to ensure wastewater and steam injections remain sequestered, rather than eventually resurfacing. Saline springs comprised of …

The influence of cementation on liquefaction resistance of sands
Cohesionless sands are known to be susceptible to failure by liquefaction when they are saturated and subjected to earthquake shaking. Considerable study has been directed towards this subject over the past 20 years in recognition of the possibility of large-scale property damage or loss of life …
