Delayed coking is an integral process in upgrading heavy, unusable crude oil to lighter, usable products such as gasoline. Coke drums are insulated, vertically oriented cylindrical pressure vessels that facilitate such a process. Due to the process of delayed coking, these drums are subjected to cyclic thermal-mechanical loading and episodes of thermal shock. One of the potential areas of failure is the shell-to-skirt junction. A skirt assembly is used to support the vessel while allowing for the drum to transition from cylindrical to conical in geometry at the bottom of the coke drum.
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).
This project will use computer modelling to aid in building a geological model of the earth’s subsurface. The model is assumed to be accurate when seismic data from the model reasonably matches seismic data recorded on the surface of the earth. The movement of wave energy within the model will then be used to aid in identifying hydrocarbon signatures in the real seismic data.
