Abstract
A method is provided of designing seismic surveys for a geographical area using controlled randomization. The method comprises the steps of selecting the geographical area to be surveyed; determining placement for one or more control areas, wherein each control area comprises a plurality of stations, within the geographical area; applying a randomization algorithm to each of the one or more control areas; creating a Fresnel fold map of the geographical area; and applying a relative standard deviation algorithm to the Fresnel fold map to confirm if the randomization algorithm has created an even distribution of data.
Claims17
A method of designing seismic surveys for a geographical area using controlled randomization, said method comprising the steps of:
- a) selecting the geographical area to be surveyed;
- b) determining placement for one or more control areas, wherein each control area comprises a plurality of stations, within the geographical area;
- c) applying a randomization algorithm to each of the one or more control areas to decimate one or more stations of the plurality of stations in each control area;
- d) creating a Fresnel fold map of the geographical area;
- e) applying a relative standard deviation algorithm to the Fresnel fold map to confirm if the randomization algorithm has created an even distribution of data;
- and
- f) generating a seismic survey design having an arrangement of the plurality of stations within the one or more control areas determined by the said application of the randomization algorithm to each of the one or more control areas.
