Abstract
A method can include receiving seismic data from a three-dimensional seismic survey of a subsurface region that includes multiple horizons; determining an order of a set of points according to data quality metric values of the seismic data, where each point in the set of points is associated with one of the multiple horizons; tracking the multiple horizons serially, where one or more switching criteria cause the tracking to switch from one of the multiple horizons to another one of the multiple horizons according to the order of the set of points; and, based on the tracking, outputting a three-dimensional model of the multiple horizons in the subsurface region.

A method comprising:
- receiving seismic data from a three-dimensional seismic survey of a subsurface region that includes multiple horizons;
- determining an order of a set of points according to data quality metric values of the seismic data, wherein each point in the set of points is associated with one of the multiple horizons, and wherein the data quality metric values comprise uncertainty metric values;
- tracking the multiple horizons serially, wherein one or more switching criteria cause the tracking to switch from one of the multiple horizons to another one of the multiple horizons according to the order of the set of points;
- and
- based on the tracking, outputting a three-dimensional model of the multiple horizons in the subsurface region.
