Advancing Waveform Tomography of Crosswell Data with Applications in the Sulphide Environment

Crosswell seismic tomography is a geophysical survey method in which the propagation of sound waves through the Earth’s crust is used to infer geological structure. An array of acoustic sources and receivers are placed into two separate boreholes, and full waveform recordings are made of the response to each source, measured at each of the receivers, the objective being a ―cross-section‖ of the geology between the two boreholes. Two attributes are extracted from this survey: i) the measured arrival times, and ii) the frequency domain components of the waveforms.

Local Buckling Response of Pipe

Onshore and offshore pipe systems may be subject to loading events that result in mechanical responde exceeding the material strength. There are technical and economic incentives for developing non-conventional, higher strength materials for use in long distance, large diameter and high pressure transmission pipeline systems. There exists uncertainty on the key factors influencing the mechanical response of these materials in pipe systems subject to large deformation loading events. This study will develop an analytical tool that can be used to assess the pipe mechanical integrity.

Evaluation of fiber-reinforced polymer composite tubulars for high-temperature environment operation

Fiber-reinforced polymer composites (FRPC) have long been recognized for their high strength-to-mass and stiffness-to-mass ratios and excellent corrosion resistance. Certain emerging technologies in the oil and gas industry do not permit the use of metallic structures, and FRPC are therefore considered as an alternative. Conventional polymer materials are usually not capable of sustaining the environmental conditions that exist for the considered applications, which includes temperatures in excess of the boiling point of water, and exposure to hydrocarbons and water.

Particle attrition at high temperature in an industrial fluidized bed at pilot plant, measurements and modeling

Syncrude Canada is one of the largest producer of synthetic crude oil for oilsands in the world, and the largest producer in Canada. Syncrude Canada uses the fluid coking process to upgrade bitumen. During the fluid coking process, coke is continuously transferred to the burner where air is used to burn some of the coke and raise the temperature of the particles, which are then returned to the reactor to supply the heat of reaction. To achieve optimum reactor performance, the particle size distribution of the coke must be maintained in a specific range.
