Abstract

"The broadband 3C-2D seismic survey was acquired in the Blackfoot Field in southern Alberta. The single-component 10 Hz geophone data were reprocessed to increase vertical resolution and provide a better seismic image of the incised valley channel fill deposits in the Glauconitic Formation. The amplitude-preserved seismic processing of the data was followed by the Kirchhoff prestack time migration. The processing parameters and algorithms used were based on parameter optimization approach. Elevation statics and surface consistent residual statics were utilized to remove near surface delays in the data. Seismic noise, such as ground roll and air blast, were attenuated effectively by various algorithms. Amplitude and phase distortions due to near surface conditions were corrected by processing of the surface consistent deconvolution and amplitude balancing. The Kirchhoff prestack time migration was applied to the data to obtain a migrated section that adequately characterizes the subsurface structure. The final stacked seismic section shows a better image of the incised valley of the Glauconitic Formation than the legacy seismic section. Log data from Well 14-09 were utilized to generate synthetic seismogram, establish seismic-to-well tying, and interpret key seismic horizons"--Abstract, page iii.
