Processing and interpretation of multicomponent seismic data from the Jackfish Heavy Oil Field, Alberta

A 2D seismic test line, acquired by Devon Canada Corporation was assessed to evaluate whether multicomponent data is worth acquiring at the Jackfish Heavy Oil Field. Both the radial and vertical component datasets were processed and interpreted. Vp/Vs was found to be a strong predictor of lithology, where it varied from 2.02-2.57 from time-thickness analysis and 2.06-2.29 from inversion results. The inversion results were more consistent than time-thickness Vp/Vs. Although the fine scale of the reservoir cannot be imaged using this seismic data, acquisition of multicomponent data would be worth the expense for the future development of this reservoir. Particularly, in the integration of time-lapse seismic, which can be used to map steam fronts and identify changes in the reservoir as a result of production. Recommendations include acquisition of offset VSPs before placement of the SAGD injectors and producers, to resolve the shale plugs, which are significant barriers to permeability in this reservoir.
