Land Seismic Data: Why you should keep everything you paid for!
Seismic surveying is a method of creating pictures of the earth’s subsurface with recorded sound waves. Seismic can be used to help characterize any subsurface resource, including oil & gas, geothermal reservoirs, CO2 storage (CCS), ore bodies for mining of critical minerals, valuable brines (lithium), and more. Acquiring new seismic data on location (i.e., a […]
EcoSeis™: A Novel Acquisition Method for Optimizing Seismic Resolution While Minimizing Environmental Footprint
All exploration and production projects, whether for oil-and-gas, mining, or clean-technology applications, begin with an accurate image of the subsurface. Many technologies have been developed to enable the acquisition of cost-effective seismic data, with high-density land seismic programs becoming commonplace…
Use of Miniaturised Seismic Sources for Reduced Environmental Impact
OptiSeis™ has a featured article in this special Land Seismic Issue of First Break. Andrea Crook, Mostafa Naghizadeh, Peter Vermeulen, Devin Gagnier, and Carl Reine present results from a 2D Field Trial conducted in the Canadian Oil Sands that compared a small, near-surface explosive source with a conventional explosive source.

Turn your seismic program into a lean, green, resolution machine
By Peter Vermeulen, Mostafa Naghizadeh, Andrea Crook, P.Geoph., and Stephanie Ross Summary Diligent seismic acquisition planning always involves careful modelling of field parameters that maximize subsurface resolution and minimize program costs. Traditionally, finding the balance between these two outcomes has been challenging but progressively achievable with skilled field management/crews, simultaneous source techniques (Crook et. al., […]
Fresnel zone binning analysis for determining optimal seismic infill stations
By Mostafa Naghizadeh, Andrea Crook, P.Geoph., and Shane Bossaer Summary The horizontal resolution of seismic surveys is determined by the Fresnel zone analysis (Sheriff, 1980). The concept of the Fresnel zone can also be utilized at the design stage of the seismic surveys for optimal positioning of shots and receivers based on the importance of […]
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 […]
