Sometimes it is useful to know whether you could still perform a particular job if the well is subsequently drilled deeper, or if it turns out that the well is already deeper than you had been led to believe. The Extended Reach calculation projects the well further out on the same trajectory (inclination and azimuth), and determines how much further it could go and still be able to get to TD with the same configuration of cable/pipe and tools.

The result is presented as a message, as in the following example.

Even if there are no plans to extend the well, this can still be an interesting result because it gives some sense of how marginal the job is. If you could in fact go much further, it gives you more confidence that you can reach the actual TD without difficulty. If, on the other hand, it turns out that the limit is reached just a few hundred feet (or meters) beyond the current TD, you should look carefully (using the Sensitivity Wizard) to see if the job feasibility is more marginal than you had realized.

Note: CTES has plans to add more features to this calculation in a future release, allowing more subtle variations in the projected well path.
