Miniaturized Source for Reduced Environmental Impact
by Andrea Crook, Shane Bossaer, Cameron Crook, Alyson Birce, Stephanie Ross – OptiSeis Solutions Ltd. Sean Contenti – Imperial Megan Boutin, Frank Sun, and Kennedy Nwafor – Suncor Energy Inc. Summary In order to reduce the environmental impact of acquiring seismic surveys in the Canadian boreal forest, a reduction in line clearing is required. This […]
Innovations in Seismic Acquisition, CSPG GUSSOW Session 3 and 4
Andrea J. Crook – OptiSeis Solutions Ltd. Abstract Acquiring seismic data in the oil sands can be challenging due to the shallow target depths, surface infrastructure, and sensitive environment. In the past 10 years, numerous seismic acquisition innovations have been developed with some providing significant benefit in acquiring high density oil sands seismic data. Areas […]
Seismic Acquisition Innovation, CSEG Virtual Learning Series (VLS)
By Andrea Crook, P.Geoph. Abstract Seismic acquisition has changed significantly in the past ten years. Recording systems have switched from cabled to cable-less/nodal systems, vibroseis is beginning to replace explosives even in areas with rugged terrain, new seismic sources are being developed, and high trace density surveys are changing the way seismic data is acquired, […]

What size should my seismic survey be? An examination of Surface vs. Subsurface area
By Andrea Crook, P.Geoph. Summary When planning a seismic survey, the total cost of the survey is dependent on the surface area. However, the optimal surface area may be significantly larger than the subsurface imaging area. This is due to the need for a survey taper which must be added to the subsurface area in […]

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 […]
Seismic Acquisition Innovations
By Andrea Crook, P.Geoph. Over the past 10 years, land seismic acquisition has changed significantly. Nodal/cable-less systems have broadly replaced cabled systems, vibroseis sources have replaced explosive sources even in areas with difficult terrain, and high-density seismic programs are becoming commonplace. This article, based on the Chief Geophysicists Forum presentation “Top 5 Innovations in Geophysical […]
Cost-Effective Seismic Exclusion Zone Mitigation Using Optimal Station Prediction (OSP) Method
By Andrea Crook, P.Geoph. For large seismic exclusion zones affecting numerous source and/or receiver stations, should all the stations within the exclusion be skidded or offset around the edges of the exclusion, or should select stations that provide the most geophysical and economic value be used instead? How do we quantify station value? Is it […]
