Microseismic imaging of hydrocarbon reservoirs treated with hydraulic fracturing

Hydraulic fracturing, also known as fracking, has become a widely used technique to extract shale gas, tight gas, tight oil, and coal seam gas from low-permeability hydrocarbon reservoirs by injecting fluid and chemicals into wellbores to create small fractures. It has significantly increase the yield of nature gas in recent years. This proposed project takes on the challenge of microseismic imaging for hydrocarbon reservoirs that are treated by hydraulic fracturing.

Effect of Mineralogy on the Application of Sensor-based Sorting Techniques

Comminution, the process of crushing and grinding ore to liberate minerals, is the most energy intensive part of the processing flowsheet and accounts for upwards of 75% of the overall energy consumption of the processing plant. Ideally we would only crush and grind those rocks that contain economically extractable amounts of minerals. MineSense has developed sensors that can detect the level of minerals in rocks and, in particular, can detect very low levels with high accuracy. This proposal is to use MineSense’s sensing technology to pre-concentrate low grade copper ores.

Carbonate Alteration Footprints of Hydrothermal Ore Deposits Year Two

Carbonate hosted hydrothermal ore deposits commonly develop narrow mineral alteration (i.e. visible) haloes, complicating exploration targeting. In contrast, hydrothermal modification of the country rock’s stable isotope composition usually extends far beyond visible alteration. Hence, stable isotope “mapping” is an effective tool to aid exploration for carbonate?hosted deposits. However, widespread utilization of stable isotope data has been hampered by its high cost and long turn-around times.

Embedding cultures of sustainability in the natural resources sector in BC

This postdoctoral study seeks to help Teck understand the practices that support and advance the company's sustainability, its employees' safety, Its collaboration with communities and Its protection of the environment. Through a series of case studies, the researcher will explore how Teck has managed the tension between regulatory compliance and sustainable innovation. The researcher will work with Teck to write case studies that highlight how individuals in the company have contributed to its sustainability, even when they were not required or incentivlzed to do so.

Development of lead-free solder alloys for electronic assembly

The objective of this project is to develop lead free solder alloys with superior mechanical and physical properties. For various reasons (some mentioned above), Sn-based multicomponent alloys with alloying elements, Ag, Cu and/or Bi are likely to be the most promising [2] [8]. For further improvement of Sn-based solder joints, in this work the effects of alloying and/or micro-alloying elements (e.g., Bi, Ag, Cu, Zn, Al, Sb, Ge, Se…) on microstructure, mechanical properties, interfacial reactions, wettability, reliability and melting behavior of Sn-based solders are investigated.

Optimizing the performance of the railway at AMIC by using data mining and advancedartificial intelligence techniques

This research project tackles a condition-based maintenance optimization problem in the railway equipment at ArcelorMittal Infrastructure Canada (AMIC). Logical Analysis of Data (LAD), a data mining technique, will be applied to exploit thousands of data records in order to identify and predict failure causes and degradation behavior of the equipment under study. New knowledge discovery approaches will be developed in order to deal with AMIC’s large scale databases. Mathematical programming and artificial intelligence techniques will be employed to develop these approaches.

Unlocking big opportunities in small packages: Application of novel nano-scale studies toenhancing mineral exploration and mining efficiency

Recent advancements in TEM sample preparation techniques using the latest generation of dual focused ion and electron beam (FIB-SEM) instrumentation allows for high-resolution examination of textures, elemental composition and structures of minerals at unprecedented resolution. These instruments enable the extraction of FIB-prepared TEM foils at any desired location of the sample (Wirth, 2004, 2009).

Large-scale Inversion of geophysical data

When using geophysical methods to gain insight into the structure of earth, large geophysical data sets are collected. Since the earth is a 3D structure, the data must be interpreted and processed in 3D to be of the most value in the exploration process. This research will develop the capability to invert large gravity, magnetics, and airborne EM datasets accurately and in a reasonable timeframe. This requires the research and development of inversion software, data visualization and QC software, and inversion setup scripts.
