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.
Claims7
1:
- A seismic survey design 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 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 resolution.
2 more elements
2:
- The method as in claim 1 further comprising the step of filtering combined weighted ranking values into two or more categories and applying different survey geometries to each category.
3:
- The method as in claim 2 wherein survey geometries are applied to correlate larger combined weighted ranking values to a survey geometry having less disturbance as compared to smaller combined weighted ranking values to a survey geometry having more disturbance.
4:
- The method as in claim 3 wherein the survey geometries are applied to correlate larger combined weighted ranking values to a survey geometry having fewer sources and receivers as compared to smaller combined weighted ranking values to a survey geometry having more sources and receivers.
5:
- The method as in claim 2 wherein the survey geometries are selected from survey geometries including:
- a) orthogonal and separate source and receiver lines having intersecting lines between the source and receiver lines;
- b) non-linear source and receiver lines having non-intersecting lines between adjacent non-linear lines;
- and
- wherein the survey geometries are ordered from least sensitive to most sensitive.
2 more elements
6:
- The method as in claim 2 further comprising the step of creating a survey design for the defined area, the survey design having a plurality of survey geometries applied to different sub-zones of the defined area.
7:
- The method as in claim 1 further comprising the step of filtering the survey design to reduce complexity of transitions from one survey geometry to another.
