Abstract

A system and method may, based on a 3D seismic data set seed point, execute a seed picking algorithm, using the first point for picking a set of second points from the data set, setting each of the points in the set of second points as the first point and repeating the algorithm. An iteration number or other attribute may be assigned to the points, the iteration number corresponding to the number of times the algorithm repeated to process the point. The attribute or a number of attributes may be displayed as a visual characteristic for each point. An iterative process may be applied to a set of seismic data points, starting at a seed data point and finding a set of next iteration seed points from among the set of points neighboring the seed point, continuing only with next iteration seed points, and recording for each of a set of data points the number of points that are found by the process when the point is used as a seed data point. Attributes may include, for example, the total number of descendants of a seed point, the direction, for example, the azimuth, of propagation of the horizon picking process, or information that relates to the order in which points are picked such as an iteration number.

Claims

1. A method for displaying 3D seismic data comprising:

accepting an indication of a first point in a 3D seismic data set;

executing using a computer processor a seed picking algorithm, using the first point for picking a set of second points from the data set;

setting using a computer processor each of the points in the set of second points as the first point and repeating the algorithm;

assigning using a computer processor an iteration number to each of the second picked points, the iteration number corresponding to the number of algorithm executions needed to generate the picked point from the first point; and

displaying information that represents the iteration number for each picked point.

2. The method of claim 1, comprising:

assigning a first value range associated with a first color and a second value range associated with a second color; and

displaying information that represents the iteration number by displaying a point as the first color when the iteration number falls within the first value range and as the second color when the iteration number falls within the second value range.

3. The method of claim 1 comprising for each of a set of points displaying a visual representation relating to the number of points that are found by executing the algorithm when the point is used as the first point.

4. The method of claim 1 comprising displaying information that relates to the direction of propagation with which the algorithm picks points.
