3D Survey Evaluation and Design Services

With design experience from subtropical swamps to the Arctic, Polaris Explorer Ltd. can provide a wide range of 3D Seismic Design solutions, optimizing subsurface imagery while controlling costs and environmental footprints.

Theoretical Design

By closely analyzing client provided:

	Target range of depths
	Previous 2D stack sections
	Existing velocity-depth models and filter panels

Polaris can supply a number of effective theoretical design options accompanied with and supported by:

	Calculated optimal bin size to maximize available high frequencies
	Multiple offset-range and unique coverage plots to ensure target fold
	Offset and azimuth plots, as well as rose diagrams showing the distribution of fold, to demonstrate required even coverage
	Migration aperture options based on dip and client requirements
	Complete receiver and source point statistics i.e. line lengths, EOL-BOL, point density, total points

Offset Design

Once the design that best meets the client's objectives is chosen, a detailed offset plan is generated using, where available:

	Digital elevation models (DEM)
	Culture spatial data (pipelines, roads, etc.)
	Geo-referenced and ortho-rectified digital aerial and/or satellite, photography
	Geographical information systems (GIS)
	Permit restrictions
	Safety and environmental concerns

Offset Design is performed to maximize geophysical integrity of the Theoretical Design while producing a safe, operationally efficient and environmentally sound program.
