In any geological sequestration projects, monitoring and verification are essential components in ensuring storage integrity. Seismic methods are regarded as a feasible way to monitor the subsurface CO2 because of their sensitivity to a rock’s pore space content. Therefore understanding the...
The Kennetcook-Windsor basin is a part of the large composite Maritimes Basin in Atlantic Canada. Subsurface seismic data indicate a very complex basinal history in terms of syn-depositional deformation and superimposition of numerous episodes of fault reactivation in the basin. Faults mapped...
Seismic velocity dispersion in crystalline rock is investigated through experimental measurements on two natural quartzite specimens. The quartzites are thermally damaged to induce low aspect ratio cracks and the shear and Young’s moduli are measured across a range of effective pressures, from...
Exploration seismology utilizes the seismic wavefield for prospecting oil and gas. The seismic reflection experiment consists on deploying sources and receivers in the surface of an area of interest. When the sources are activated, the receivers measure the wavefield that is reflected from...
Logistic and economic constraints often dictate the spatial sampling of a seismic survey. The process of acquisition records a finite number of spatial samples of the continuous wave field. The latter leads to a regular or irregular distribution of seismograms. Seismic reconstruction methods are...
A nonlinear finite element model was developed to study the behaviour of unstiffened steel plate shear walls. The model was validated using the results from quasi-static and dynamic experimental programs. With the validated finite element model, the performance of 4-storey and 8-storey Type D...
Abstract: Impressive progress has been made in the last 25 years in recognizing liquefaction hazards, understanding liquefaction phenomena, and analyzing and evaluating the potential for liquefaction at a site. Recent findings related to the application of the seismic cone penetration test (SCPT)...
Local time-frequency analysis, also known as spectral decomposition, allows for a more detailed interpretation of time-series by providing the evolution of the frequency spectrum through time and has proven to be a useful seismic attribute for exercises such as reservoir characterization. This...
Vector interpolation and regularized elastic imaging of multicomponent seismic data
Historically seismic data processing has relied on the acoustic approximation to process single component data under the simplifying assumption that the recorded wavefield consists mainly of compressional wave modes. With the advancement of multicomponent seismic technology there is an increased...
Wave Speed Measurements of Grosmont Formation Carbonates: Implications for Time-Lapse Seismic MonitoringDownload
The Grosmont Formation is a Devonian-aged carbonate platform complex that is estimated to hold over 64.5 billion m3 (406 billion bbl) of bitumen in place, accounting for a significant portion of Canada’s total hydrocarbon reserves. Despite this, the Grosmont formation has largely been undeveloped...
