Transitioning to High Density Vibroseis Seismic Acquisition: A Case Study

Andrea Crook OptiSeis Solutions Ltd. Rob McGrory, Nathan Baker, & Adam Westlake, Crescent Point Energy Summary In general, seismic acquisition in the Western Canadian Sedimentary Basin (WCSB) has been conducted using primarily explosive sources, whereas vibroseis acquisition has been limited to areas with relatively flat topography. With the recent advances in seismic acquisition and processing […]

Simultaneous Source vs. Regular Vibroseis Acquisition – A Direct Comparison

By Andrea Crook, P.Geoph. Summary Simultaneous source acquisition has proven to be effective at increasing trace density without incurring significant increases in seismic acquisition cost. As a result, most simultaneous source datasets have significantly higher trace density than previous datasets requiring decimation of the simultaneous source dataset or interpolation of the regular dataset to effectively […]

Optimal Restriction Modeling: A New Approach to Station Positioning

By Keith Millis, Cameron Crook Summary Surface restrictions to seismic acquisition increasingly limit the ability to place stations at their theoretical locations. Consequently, the acquisition design process is faced with increased pressure to model programs with surface perturbations in mind (Cooper, 2004). An optimal restriction modeling method requires reshaping the surface design process to one […]

The Benefits of Receiver Infill Stations: A Technical and Operational Case Study

By Keith Millis Summary Surface restrictions to seismic acquisition pose an increasingly complex challenge to imaging desired targets. Some surface restrictions are time variant and require the acquisition team to be highly adaptable and responsive to changing conditions. There are aspects to nodal systems that can enhance this adaptability. Discussions on the benefits of nodal […]
