An understanding of the soil load and restraint on pipelines due to relative pipeline/soil movement is required to assess the pipeline mechanical response that may affect pipeline serviceability or integrity. Current engineering practice for pipeline/soil interaction is based on idealized structural-based numerical models that evaluate pipeline mechanical response using beam elements and soil behavior using discrete spring system. The soil spring are characterized by independent load- displacement relationships for only principal directions (i.e.
In preparation for the 2011 UNESCO World Heritage Site Designation bid, Lambton County’s Oil Museum of Canada is undertaking a new project. The Oil Springs Social History Project will explain what the community of Oil Springs looked like when its population exploded as a result of the discovery of ‘Black Gold’. Described as a site of great national and international significance, the oil fields continue to flow today using much of the technology which made this sleepy town a bustling community in the 1850s and 60s.
The intern will work closely with the PPIC Sahara system design engineers to develop a new security control system to protect both the software and hardware of the Sahara system. The tasks will 1) propose a true random number generator based on the dsp controller 2) implement a cryptographic algorithm based on the random number generated 3) develop the hardware and software for the proposed security system. This security system will provide an effective protection to the Sahara equipment from unauthorized use and protect the economic interests of the company.
Coke drums are major petroleum refinery and oil sands upgrading facilities associated with the processing of oil sands bitumen. The service lives of current coke drums are limited and frequent repairing is required due to severe cyclic thermal-mechanical load experienced. The objective of this project is to find root causes causing the damage/failure through more accurate global and local elastoplastic analyses on the coke drums by using new developed material constitutive model.
The objective of this project is to develop a computational simulation model designed to determine how the resource-extraction industries of oil, gas and forestry influence woodland caribou (Rangifer tarandus) habitat selection and use in west central Alberta. Specifically, an agent-based model will simulate caribou as individual agents that 1) are capable of making trade-off decisions to maximize their reproductive success and survival, 2) are spatially aware of their surrounding environment, and 3) can learn where to forage, while concurrently avoiding predators and habitat disturbance.
The internship objective is to establish a reliability based design framework for high strength linepipe subject to internal pressure, axial force and end moment for monotonic loading conditions. Linepipe grade material with specified minimum yield strength (SMYS) equal to or greater than Grade 550 (X80) is defined as high strength linepipe. The mechanical performance design criteria will be established through the development, calibration and validation of numerical modeling procedures such as finite element.
Oil and gas resources are hidden deep within the earth in geological structures which form reservoirs for these fluids. Finding these reservoirs, and monitoring the flow of fluids within these structures requires advanced imaging technologies and algorithms for the successful recovery of these valuable resources. This project will develop a newly proposed mathematical approach to imaging these structures, known as full wavefield tomography (Brenders and Pratt, 2007).
In this project, a comprehensive review of relevant literature and case studies regarding landfarming of oily sludge will be conducted, and the optimal landfarming operation strategies will be proposed. A number of field experiments will be implemented to examine the impacts of different environmental factors on microbial activity. Specifically, the impacts of bulking agents and nutrients on bioremediation efficiency will be investigated through sludge landfarming at various experimental plots, while the method of factorial design will be used to design such experiments.
The test characterization of the stress-strain relationship and the fatigue/failure behaviour under combined mechanical-thermal cyclic loadings for pressure vessels in the petrochemical industry is quite expensive and time consuming. An alternative approach is the finite element numerical analysis which requires an accurate and reliable mathematical constitutive model for the metallic materials. In this project, a temperature-dependent elastoplastic material model will be developed.
Geo-X Processing, Divestco Inc., a Canadian seismic processing contractor, is seeking to enter a new segment of the market, the so-called “depth imaging” market, by Q3 2007. The company is currently developing a comprehensive suite of depth imaging algorithms aimed at competing in the above market, but currently lacks a certain sophisticated tool. Such a tool has been recently developed at the University of Calgary, called the “FOCI algorithm”.
