Abstract
The invention relates to systems and methods for designing seismic surveys to enable seismic data acquisition with a reduced environmental impact and lower survey costs. The methods include incorporating surface and subsurface data and associated parameters for a proposed survey area and assigning weighting values to the relative ranking of the parameters for a particular area and thereafter designing a source/receiver plan based on combined and weighted parameters.
Claims19
A seismic survey method comprising the steps of:
- for a defined land and/or marine area:
- a) obtaining two or more data sets for the defined land and/or marine area wherein each data set includes relative ranking values for sub-zones within the defined area;
- b) over-layering the two or more data sets;
- c) for a defined resolution of the over-layered data sets, applying a weighting factor to each relative ranking value for each data layer and summing weighted ranking values across all over-layered data sets to determine a combined weighted ranking value for the defined resolution;
- and
- d) generating a seismic survey design having a plurality of survey geometries for the defined area, wherein a survey geometry selected from the plurality of survey geometries is applied to each sub-zone within the defined area according to the combined weighted ranking value determined for each sub-zone at the defined resolution.
