ABSTRACT

During March 2000, the Consortium for Research in Elastic Wave Exploration Seismology (CREWES) at the University of Calgary, with financial assistance from the Alberta Oil Sands Technology and Research Authority (AOSTRA) and Husky Energy Inc., acquired a high-resolution multicomponent seismic survey at the Pikes Peak heavy oil field located east of Lloydminster, Alberta/Saskatchewan. The 3.8 km 3C-2D survey consisted of recording vibroseis sources into conventional vertical component geophone arrays, single microphones and single 3C geophones.

Source gathers of both vertical and radial components show good reflection data with a high signal-to-noise (S/N) ratio. The microphone source gathers are dominated by the strong air wave generated by the vibroseis source. Structural and migrated P-P and P-S stacks of both the conventional vertical geophone arrays and single 3C geophones also possess a high S/N ratio. A cursory examination of these sections show that they adequately image the target area. The analyses of the data from the different portions of the survey remains as future work.
