A method for tracking seismic events such as boundaries of formation layers of earth formations is disclosed.

The method tracks such event through the grid of data by sequentially establishing areas or "tiles" of data about the starting point. The tiles are defined by data points (1-8) of the grid.

Why it's free to use
- Filed June 10, 1991 and granted June 3, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 10, 2011.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
