Abstract

"The 3C-2D multicomponent seismic survey was acquired in the Blackfoot Field, which is located 15 km southeast of Strathmore, Alberta. The 2 Hz vertical component data were reprocessed to better image the target reservoir, the Glauconitic sand formation at approximately 1150 ms. The zone of the major reflector at about 1550 ms was also taken into consideration to determine the better seismic section for further processing. The main characteristics of the converted wave processing, such as common conversion point (CCP), asymptotic binning, gamma ratios, receiver statics, rotation of the data, positive/negative offsets, and anisotropy, were also summarized in this study.

The processing chart was determined by testing a number of parameters and methods. Different types of deconvolution, static corrections, and migrations were applied to the seismic data to better image the target zone. The noise attenuation steps reduced the ground roll noise and increased the signal-to-noise ratio. Two-dimensional Kirchhoff prestack and poststack time migration were utilized to image the subsurface. Since the lithology discrimination between the target reservoir and the neighboring shales is the main issue in the study area, the spectral whitening was applied to the migrated sections to increase the resolution and the appearance of the reservoir. In this context, the obtained results suggest that the prestack time migration offered stronger amplitudes in the target zone, and the channel cuts were observed clearer than the poststack migration"--Abstract, page iii.
