During periods of rapid drilling or when multiple special analyses are run, an additional logger or sample catcher is often added to each tour.

During periods of rapid drilling or when multiple special analyses are run, an additional logger or sample catcher is often added to each tour.

In some mature exploitation areas, companies will hire one mudlogging contractor to monitor several wells at a time. In such cases, rig crews are required to catch cuttings samples for later analysis by the logger. These samples are often caught as time allows and are not as useful as cuttings that have been systematically caught and lagged (see chapter on [[Wellsite math]]).
